Eco-industrial park (EIP), as a significant practice of industrial ecology, has become one of the important carriers in China's construction of circular economy and sustainable development. However, the traditional development chain of eco-industrial parks is so single that less attention is paid on agriculture, industry and services to seek a more extensive cooperation mechanisms, leading to the problems of a unclear and indistinct regional feature in current development tendency of eco-industrial parks. Therefore, the construction framework of agri-industrial ecological park (agri-industrial EIP) are proposed in this paper,including conception,development model, construction significance and principles of design. The conception of agri-industrial EIPs is defined as follows: agri-industrial EIPs are regional industrial symbiosis which are based on the core of industrial parks and composed of "social-economic-nature" complex involving the various types of agriculture-related enterprises, cooperative organizations,farmers, villages and farmland around the park. Then,according to the enterprise scale and scope of radiation area, it can be divided into three levels: (1) small level involving enterprise combined with farmers, (2) meso-level involving core parks combined with hinterland, (3) regional level involving. Meanwhile, the construction of agri-industrial EIPs can benefit in comprehensive utilization of resources in the surroundings and the logistics cost savings, competitive advantage of industrial symbiosis network will also be improved, the goal of "industry promotes agriculture, production promotes environmental protection" will be achieved. In the view of system optimization method, the paper has put forward five principles for designing agri-industrial EIPs: transverse coupling, longitudinal closing, regional combination, functional orientation and employment increasing. Based on these conceptions and design principles, we take national economic-technological development area (NETDA) in Zhengzhou as a case study, which is the only state-level industrial parks in Henan province which is famous for the largest production of agricultural and sideline products in central regions, convenient transportation network and rich land resources. Combined with regional characteristics and resource advantages, NETDA was constructed as agri-industrial symbiotic industrial ecosystem by three product lines and a service chain,which are as follows:1) the first product chain, which focuses on the products of small or medium-sized and low-emission vehicles provided for farmers on back-land of the agri-industrial EIPs,2) the second product chain, in order to meet the demand of agricultural mechanization, which focuses on agricultural machinery provided by enterprises of equipment manufacturing in the park for the need of rural production in the surrounding hinterland, 3) the third product chain, which focuses on agricultural products produced in hinterland to strengthen the connection between food processing enterprises in the park with the rural in hinterland through the way of "order agriculture",4) service chain, with the purpose of meeting technology and information demand for the rapid development of agriculture, which focus on technical guidance and information services provided for agricultural development in hinterland, rural residential environment construction, rural employment by the agricultural headquarters in agri-industrial EIPs.In conclusion, the construction of agri-industrial EIPs is not only the specific implementation of theory in the industrial symbiosis at the regional level, but also is an innovative application of compound ecosystem theory in the level of industrial parks. 参考文献 相似文献 引证文献

The Crack Control of Reinforced Concrete Structures

Difficulties and prospects of fishways in China: An overview of the construction status and operation practice since 2000

Fish passage facilities are an effective means for mitigating the effect of barriers (e.g., dams, weirs, and road crossings) on migrating fishes. Fishways in China were first recorded in 1958. The efficiency of fishways is one of the evaluation indicators of a river ecosystem's health. This paper summarises and analyses China's construction of fishways since 2000. Three typical cases (Changzhou water control project, Laolongkou water control project and Cao’e river gate project) are presented to illustrate the current situation of fishways in China. A discussion is also provided regarding ideological guidance, theoretical systems, technical means (monitoring), research content, legal systems and other aspects to elaborate the deficiencies and challenges of China's fishways. Thus, a number of prospects, such as proposing the design criterion of fish passages, performing basin ecological protection planning, and implementing adaptive management are urgent and necessary for further development of fishways in China.

The Last Planner System in China's construction industry — A SWOT analysis on implementation

The Last Planner System™ (LPS) is well-documented in the literature, and has sometimes been used to represent lean construction or lean project management. LPS aims to achieve reliable workflow by encouraging foremen to have a sense of ownership of the project programme and to build-in their commitment into it. This study reports on the perceptions of Chinese building professionals of the application of LPS in Chinese construction projects. It reveals that several components of LPS have already taken place in large Chinese construction firms. Further, this study employs a SWOT analysis to examine the possible strength, weakness, opportunity, and threat factors that might have an impact on implementation of LPS in construction projects in China.

However, compared with developed countries, the progress of BIM development in adoption and identify key barriers which strongly impact the BIM adoption so as to propose corresponding measures to remove the key barriers. A survey about barriers impact was carried out among Chinese construction practitioners. By using AHP(Analytic Hierarchy Process),41 barriers of BIM in Building Industry of china were identified. In the last part of the thesis, a roadmap of BIM adoption and application in china was developed based upon the measures and characteristics of barriers of the BIM adoption in China.

Exploring the challenges to industrialized residential building in China

Industrialised building (IB) is considered by many to have an important role to play in China's residential construction industry due to its potential for improved quality, productivity, efficiency, safety and sustainability. It is surprising, therefore, that although a large number of construction programmes have been completed in the country in recent years, very few have been built in this manner. Quite why this situation exists is unknown. The well-known problems with IB, such as the constraints placed on designer freedom, may be the cause. It is equally possible that, as is typical with developing countries such as China, cost or government issues dominate. On the other hand, in comparison with other countries, the construction industry in China has been widely criticised for its lack of modernity. Either way, there is an urgent need to assess and understand the hindrances to the adoption of IB in residential construction in order to identify what corrective measures, if any, need to be taken.Towards this end, we first identify a set of critical factors (CFs) for assessing the hindrances to IB adoption in China. This involves the analysis of research data collected by a questionnaire survey of experienced housing developers and professionals working in China's construction industry sector. Fuzzy set theory is used in the selection of the CFs. These CFs comprise, in rank order: higher initial cost; lack of skilled labour in IB; manufacturing capability and involvement issues and product quality problems; lack of supply chain; lack of codes and standards; and lack of government incentives, directives and promotion. The establishment of the CFs provides a basis for local construction sectors to better equip themselves for future implementation of IB. The findings also indicate a current need for formulating improved policies and strategies to encourage the further development of IB in China at present.

Detection and Control of Building Materials Quality
