Green city and regional environmental economic evaluation based on entropy method and GIS

Abstract

In today’s society, the environment is a frontier topic, and the topic of environmental sustainability has attracted attention. There are also many sustainable development ideas in the economic field. The main topic is circular economy, which is mainly to cultivate a harmonious coexistence environment for the development of man and nature by strengthening the construction of the ecological environment and ecological industries. Therefore, when solving environmental problems, we must adapt measures to local conditions and develop a circular economy to fundamentally solve the problems that have always existed between resources, environment and development. For regional economies, we must create new ideas on the road to industrialization and make full use of Resources provide a foundation for the realization of the overall construction goals of a well-off society in the near future, and contribute to the realization of grand goals. In this study, we will take the environmental problems in a certain area as an example, aiming at the environmental problems in the area and the goals of national policies for ecological environment construction, summarizing the content of existing research, and conducting a preliminary analysis of this content. A framework of thinking based on ecological environment quality evaluation is proposed. Technically, remote sensing and geographic information systems are used, and the survey results and research results summarized with sufficient reasons are used to conduct a single-factor analysis of the ecological environment in the area, and establish a relevant database of the ecological environment in the area. The focus of this article is to establish a complete set of evaluation system compared with the current situation and development of circular economy, and compared with foreign circular economy development models. The main contents include the evaluation of the reduction of resource input, the evaluation of the effect of resource recovery and reuse, the evaluation of the reduction of pollution emissions, the evaluation of the improvement of ecological environment quality, and the evaluation of the comprehensive development level of the socio-economic development of the area. On the basis of some evaluations, it is necessary to use the entropy method to make a comprehensive analysis and evaluation of regional economic development. The evaluation system of this article is relatively complete and comprehensive, integrating resources, environment and economic benefits. • Adapt measures to local conditions and develop a circular economy. • Aiming at the environmental problems in the area and the goals of national policies for ecological environment construction. • Summarizing the content of existing research, and conducting a preliminary analysis of this content. • Use the entropy method to make a comprehensive analysis and evaluation of regional economic development.
