In high-performance computing (HPC) systems, energy and power considerations play an increasingly important role. This work aims to ensure the implementation of China’s green and ecological concepts, respond to China’s strategy of building an environment-friendly and resource-saving society, and actively promote the construction of sustainable development campuses. First, the theoretical basis of sustainable energy campus architecture is described. Next, the teaching feedback model under HPC is constructed. Finally, with the evaluation results of students’ task completion processes and students’ task works as measurement indexes, the corresponding data is collected and comprehensively evaluated and analyzed to verify the effectiveness of the model. The analysis results indicate that most students are able to complete tasks within two hours; however, their proficiency with multimedia technology is inadequate, and they lack initiative in the learning process. There is a correlation between the overall evaluation of task performance and the students’ level of understanding of the tasks. By implementing a teaching feedback model, students’ learning enthusiasm and the quality of their work improved, providing effective educational support for promoting sustainable development on campus. Overall, the awareness of using computers and other multimedia technologies among students is not strong, and their learning process is relatively closed, with insufficient enthusiasm and initiative. This model can achieve the acquisition, integration, and statistical analysis of teacher feedback information. The model can realize the acquisition, integration, and statistical analysis of teachers’ feedback information. This work hopes to use this learning and feedback mode in practical teaching to address specific problems in computer multimedia courses.

Research on the Resource Treatment and Comprehensive Utilization of Carbon Containing Wastes Using Pyrolysis–Gasification Two-Stage Recycling

Carbon containing waste has a certain calorific value and utilization value due to the presence of carbon elements. However, the current treatment methods are mostly traditional landfill disposal, incineration, or expensive physical and chemical reaction methods, which clearly do not comply with the rules of the current clean and resource-saving society. In this paper, a new technology and system for carbon containing wastes is proposed, which comprehensively treats and recycles carbon containing wastes, including solid waste, wastewater, waste gas, etc., using pyrolysis–gasification two-stage-cycle technology. The calculation results indicate that the technical scheme proposed in this article is feasible and can achieve the recycling of intermediate and final products, the efficient and clean utilization of carbon containing waste, and the graded utilization of energy. The clean utilization rate of carbon containing waste can be effectively improved, the energy consumption and cost of separate treatments can be reduced, and zero waste emissions can be completely achieved by the comprehensive pyrolysis–gasification two-stage-cycle treatment and resource utilization technology, which is one of the preferred solutions for future resource-saving societies.

CH3COONa·3H2O/flaky modified vermiculite composite phase change materials enhanced phase change behavior and thermal storage through curing lotus root starch modification

With the establishment of the basic policy of environmentally-friendly and resource-saving society, the energy storage technology using phase change materials (PCMs) as the medium has developed unprecedentedly. Hydrated salt PCMs plays a vital role due to its large latent heat density, wide range of phase transition temperature, and high thermal conductivity. However, the problems of low enthalpy, poor thermal stability and phase separation are critical drawbacks of composite phase change materials (CPCMs), which limited the extensive use in fields of energy storage. In this work, the flaky vermiculite (MEVM) was fabricated by the acid treatment and alkali leaching, and the cured lotus root starch (CLRS) was embedded and used to enhance the water holding capability of hydrated salts. A series of sodium acetate trihydrate (SAT)-CLRS/MEVM was prepared, and the form-stable composite phase change materials (SAT fs-CPCMs) were obtained. Results showed that the encapsulation capacity of SAT fs-CPCM with 2 wt% CLRS was 71.3 %, and the thermal enthalpy reached 180.1 J/g, which was 43.7 % higher than that of SAT/MEVM. The contact angle of the sample with H2O was 22.24°, which represented hydrophilicity. SAT fs-CPCM also had good thermal stability and thermal reliability. After 200 thermal cycles, the enthalpy loss of the SAT fs-CPCM was only 5.2 %, and the 200th enthalpy value was 173.72 J/g. In addition, Calculations indicated that there were hydrogen bonds and van der Waals weak interaction between SAT and CLRS. This work provides a new perspective for the improvement of the thermal properties of hydrated salt and offers a promising approach for the applications of PCMs in cost-effective energy storage.

An empirical approach for enhancing farmers' concentrated residence strategies: A case study in Jiangsu Province, China

The concentrated living of farmers is an important engine for rural revitalization and a new type of urbanization, thus is of great significance for the construction of a resource-saving society. Due to rapid economic development in China, some farmers have successfully urbanized through rural–urban migration, but still more than 500 million farmers, have not migrated yet. Concentrated residence has long been recognized as the best strategy to help Chinese farmers to achieve local urbanization, and has been paid much attention in the local, regional, national and global scientific community. Although robust models and policies are still lagging behind because of insufficient datasets and models. In this study, empirical model has been used in which concentrated residence cases of farmers in Yancheng City, Jiangsu Province of China taken as a case study, and strength (S), weakness (W), opportunities (O) and threats (T) as the criterion layer to identify 16 influencing factors as the index layer. For this study, data was collected during 2021 & 2022 by questioner-based survey from 6 different settlements, and AHP analytic hierarchy model integrated with SWOT was used to built farmers' concentrated residence strategies. The positioning coordinates of this study show the following weightage like S (0.480, 0), W (-0.098, 0), O (0, 0.306), and T (0, −0.116) which clearly mentions that S and O as positive influences, W and T as negative influences, and locates the respective total weights. Therefore, empirical results indicate that SO (growth-oriented) strategy should be emphasized to build robust strategies for concentrated residence of farmers. The findings of this study can provide a benign model for centralized residence for local governments, village collectives, and farmers withdrawing from homestead, and help to promote the sustainable development of society.

The side effects of local government debt: Evidence from urban investment bonds and corporate pollution in China

Local government debt plays a vital role in achieving financial financialization and regional economic growth. However, the environmental side effects of the debt-financed infrastructure development model have received little attention. Using a large panel data of Chinese enterprises from 2007 to 2016, we explored the relationship between local government debt in terms of urban investment bonds and corporate pollution emission. We observe that the increase in local government debt exaggerates the intensity of COD emission, equal to 26% of the average. This pollution-promoting effect remains after a series of robust checks. In heterogeneous analysis, local government debt is more likely to affect enterprises located in coastal areas, from pollution intensive industry, operating in regions with weak fiscal strength and operating in regions with low governance quality. The mechanistic exploration from government environmental governance and financial constraint reveals that the local government debt increases corporate pollution when the local fiscal finance emphasizes economy over environmental governance, which has been alleviated after the central government advocates the construction of an environmentally friendly and resource-saving society; An increase of corporate pollution is also possible when local government debt increases the financing constraints of enterprises. We also unveil the source of corporate pollution, and find that if enterprises do not actively adopt environmental strategies either in terms of “end-of-pipe” or “source prevention”, they choose to emit more to face with the onslaught of local debt. This study uncovers the environmental impacts of government debt, and explores the potential mechanisms, which can help reduce pollution from local government debt and achieve global climate governance.

The Coordination of Environmental Protection and Female Discrimination Based on the Concept of Affirmative Action.

With the development of society, the chemical industry is expanding, and the hazy weather everywhere is becoming increasingly frequent, already affecting people's lives and causing them to pay more attention to environmental issues. Therefore, this paper highlights the role of women in environmental protection by studying the coordination of environmental protection and female discrimination based on the concept of affirmative action. Through this study and a survey, we found that China has not yet realized that women's participation in environmental protection plays a key role in improving the quality of our environment and the development of ecological civilization. However, we should clearly understand that environmental issues are not only personal, they are related to the survival and development of a country, and as a member of that country, both women and men should have the right and obligation to protect the environment. Therefore, this article discusses the concept and meaning of affirmative action and gender discrimination in the context of research on these concepts, discussing the problems and phenomena that women encounter in environmental protection. These include the system of women's environmental protection, gender issues for women in society, and the unequal treatment from the Government based on some studies. Through the study and analysis of the system of women's environmental protection, the role and position of women in this regard is summarized. Finally, it is suggested that, for the construction and development of ecological civilization in China, it is necessary to fully integrate ecological civilization into all aspects of society and pay attention to environmental protection issues. Therefore, we should pay attention to the role of women in environmental protection, provide corresponding policies, and actively encourage women to partake in environmental protection in order to build an environmentally friendly and resource-saving society together.

Research on parametric design method of solar photovoltaic utilization potential of nearly zero-energy high-rise residential building based on genetic algorithm

Building a resource-saving society and achieving energy conservation and emission reduction is a strategic decision for China's current social development. Zero-energy buildings realized by the synergy of low-energy energy-saving technologies and renewable energy utilization technologies have become the ultimate quantitative index of sustainable buildings. Therefore, from the perspective of the development trend of residential buildings, near-zero-energy residential buildings oriented to zero energy consumption will become one of the goals of residential building development in China in the future. Recently, building performance simulation technology has been widely used for energy-efficient design. This study focuses on zero energy oriented residential building design, taking the integration of complex systems in terms of building design, energy technology, and economics as the guide, establishing the coupling relationship between the parameters of each system, and adopting a multi-objective optimization approach to find the optimal energy-saving design solution. Based on the parametric design tool of the Grasshopper platform and the Non-Dominated Sorting Genetic Algorithm II, the study explores a multi-objective optimization design approach for zero energy oriented residential buildings to achieve the lowest total air-conditioning and heating load, the highest photovoltaic power generation, and the lowest investment cost. Nine control variables that affect these three objective functions are quantitatively evaluated and analyzed. The design process and analysis model for the multi-objective optimization of zero energy buildings are established, and the feasibility and technical routes for achieving zero energy for typical building types in different climate zones are compared and analyzed, providing a theoretical basis and parametric design method for the practice of zero energy residential building design across different climate zones in China.

Application status and development trend of geothermal energy heating technology

With the rapid development of economy, people have higher and higher requirements for the quality of life. The traditional heating mode has serious pollution, uneven temperature, inconvenient installation, poor comfort, large energy consumption and low social benefits. It has been unable to meet people's pursuit of modern quality of life and the construction needs of environment-friendly and resource-saving society. The northern part of China is cold in winter, so it needs indoor heating. As the traditional heating mode has the problems of high energy consumption and environmental pollution, it needs to be updated and optimized. Based on the classification of geothermal energy heating technology, this paper expounds in detail the basic concepts, development and application status of shallow ground source heat pump technology, hydrothermal heating technology and middle-deep buried pipe heating technology. The emergence of geothermal energy heating technology has effectively solved a series of problems existing in traditional heating and has been widely used. In order to explore the heating potential of geothermal resources and its value in the "dual carbon" goal, the endowment and distribution characteristics of geothermal resources in China are briefly described, and the applicable geothermal energy supply models in different regions are given. By summarizing the existing reported research directions and related achievements of geothermal energy heating technology, from the perspective of operation mechanism and application practice, the technology development in this field is prospected.

Impact Analysis of Environmental Regulation and Improvement of Agricultural Economic Efficiency on Living Environment Based on Systematic GMM Model.

The living environment is of vital importance to human beings and is also the basis for their survival and development. Along with the accumulation of people's production and living experience, people are seeking their own development while studying the living environment more deeply. In recent years, various regions and departments have conscientiously implemented the relevant decisions and deployments. They have promoted the construction of rural infrastructure and the equalisation of basic public services between urban and rural areas, so that the rural living environment can be gradually improved. The rapid development of urban-rural integration has brought great opportunities and challenges for rural development, making rural development issues increasingly complex and affecting the effectiveness of the construction of a new rural habitat. At the same time, the agricultural economy is the basis of national economic development, and the ecological environment provides a certain amount of material environment for the development of the agricultural economy. Therefore, research on the harmonious development of the agricultural economy and the ecological environment has always been a hot issue for the authorities concerned. After all, China's agricultural economic development mode is characterized by a rough-and-ready approach, and the agroecological environment continues to deteriorate, leaving the issue of sustainable agricultural development to be resolved. What is worse, in the practice of agricultural production, the related agricultural activities have brought serious pollution to the environment. Specifically, the carrying capacity of the agricultural ecological environment is declining, leading to an increasingly serious conflict between sustainable agricultural economic development and the construction of an environmentally friendly and resource-saving society. In China, although the industrialization process is accelerating, the agricultural population still accounts for a large proportion of the population. As people's living standards continue to improve, a favorable living environment has become an urgent need for farmers. As a result, strengthening the construction of rural infrastructure, improving rural living conditions, and improving rural environmental sanitation are important issues that need to be addressed urgently. Therefore, to further investigate the impact of environmental regulation and agricultural economic efficiency on the habitat, this study constructs a systematic GMM model using panel data for 30 provinces and regions in China from 2011 to 2021.

Research on the Whole Process Control of Cold Chain Transportation under the Background of Resource Saving

With the continuous improvement of people’s requirements for food safety and quality, cold chain logistics has become the focus of much attention in the logistics industry. my country’s Cold chain logistics is developing rapidly in China, but the overall level is low, and the cold chain loss rate of fresh agricultural products is high, causing huge waste. Road transportation is an important part of cold chain logistics. 90% of the freight volume in the cold chain logistics is completed by road transportation, but the proportion of broken links in the transportation process reaches 60%, which seriously affects service quality of cold chain logistics. Cold chain logistics is directly related to people’s life safety and physical health, and it is also an important way for my country to build a resource-saving society. However, one of the problems with the inadequacy of the cold chain is the incomplete management system, extensive management methods, and imperfect management systems and standards of the cold chain transportation enterprises, refrigerated and heat-preserving vehicles and other basic elements by the industry management department. Therefore, it is necessary to establish a closed-loop management and control system for the entire process of “market access-process monitoring-service evaluation-joint rewards and punishments” centering on road cold chain transportation. The high-quality development of logistics creates a good market environment, improves the service quality and management level of cold chain transportation, and reduces the loss of agricultural products in the cold chain logistics process.

Unfolding the synergy and interaction of water-land-food nexus for sustainable resource management: A supernetwork analysis

Given the large amounts of water, land, and food embodied in the trade of goods and services, a key step in decoupling extensive resource consumption from the economic system is to understand the full impact of socioeconomic development on the water-land-food nexus. This study integrates input–output analysis, ecological network analysis, and Dempster–Shafer evidence theory into a supernetwork model to detect the water-land-food nexus among economic sectors with an aim to explore effective strategic paths for resource management and to facilitate the construction of a resource-saving society. Results show that most sectors of China are resource inefficient and that all resource systems are unsustainable as reflected in the low performance of their Finn's cycling index and system robustness. Meanwhile, results of flow networks analysis show an extremely uneven land resource allocation where more than 94% of the land used in China is classified as direct agricultural land. The water-land-food nexus can gain resource saving bonus via enhancing the robustness of economy. However, the co-benefits from the nexus are negligibly small for the resource utilization efficiency. The results also indicate that the relevant resource-saving policies on food and water are highly likely to gain resource co-benefits due to their similarities in sectoral importance. Correspondingly, a set of strategic measures, including adopting a tiered resource price, deepening industrial convergence of agriculture, enhancing agriculture-food nexus, and managing water or land use from the food consumer side, are designed to build a resource-saving society. The findings of this study can provide additional insights into the impacts of the economy on the water-land-food nexus, which is beneficial for achieving an efficient and coordinated management of resources.

RETRACTED ARTICLE: Smart city information acquisition system based on internet of things

In order to develop an information acquisition system and apply to smart city, the information acquisition system using four-meter centralized reading is designed. At present, all provinces and municipalities in the country are vigorously promoting the construction of household electricity, water, gas and heat, and remote meter reading technology of electricity, water, gas and heat is also becoming more mature. In particular, the electricity information acquisition system pioneered by the State Grid Corporation of China (SGCC) has already realized the full coverage of the remote meter reading network of residents, and laid the foundation for the integrated acquisition of electricity, water, gas and heat by family. However, from the present point of view, the management of electricity, water, gas and heat is self-organized. Though there are many similarities in the problem of meter reading, due to the reasons of industry management, resource sharing cannot be formed. The basic structure of the current electric information acquisition system, the remote and local communication technology, and the benefit produced by the meter are introduced. A technical scheme for collecting four kinds of meter meters by using the existing power information collection network is put forward. The use of four-meter centralized reading shows that the technical plan about four-meter centralized reading is in line with the direction and requirements of sharing and building the resource-saving society. Compared with the other system, it is in the leading position. In conclusion, this new smart technology has achieved certain effect in the practical application and the application prospect is very wide.

Research on Polyurethane Elastomer Abrasion Protection for Impeller of Water Pump

The pumps used in the Guhai Pumping Irrigation Project were suffered from sediment abrasion in the long term and their flow passage components, including impellers and pump shells, were also seriously abraded, which led to common problems of poor reliability, low operation efficiency and high energy consumption in almost all the pump stations. Therefore, these problems had made these pumps unable to satisfy the requirements for construction of resource-saving society and development of hydraulic engineering modernization. The steel plate welded impeller technology was a new technique specially developed to solve the serious abrasion of pump impellers. However, the results of long-term application of this technology had demonstrated that the composite resin mortar coating had a limited capability to resist cavitation and thus the parts which are fragile to cavitation on the impellers will fall off easily, which further aggravated the impeller abrasion. After one irrigation season, there were multiple penetrated holes occurring on the impellers, which significantly affects the operation efficiency of the pumps. In order to solve the cavitation resistance issue of composite resin mortar. The polyurethane elastomer technology was developed for the first time, which the polyurethane material with the currently best performance in cavitation resistance was adopted, and the appropriate promoters were added into the polyurethane to improve its properties. In addition, high-strength binder and mechanical connection mode were developed in this technology, which greatly enhanced the binding strength between the polyurethane coating and the pump impellers. Besides, vacuum casting technique was adopted to obtain the pump impeller coating which had excellent performance in abrasion and cavitation resistance. This technology was firstly tested in the Guhai Dazhanchang Pump Station in March 2015. After one and half years operation, it is found that the coating had been improved obviously, and the pumps had long-term stable operation efficiency, which had reached the anticipated testing goal. It is provided reference for the pump stations in Yellow River Diversion Project and pump manufacturers to solve the pump impeller cavitation problem.
