Abstract

The ecological environment of China is facing much more pressure with the continuous growth of population and energy usage. China pays more attention to improving the ecological environment quality with the ecological civilization development in the situation. The key problem is to construct a scientific and reasonable comprehensive evaluation index system guiding the ecological environment quality improvement. This paper creates a comprehensive evaluation index system of ecological environment quality based on the Pressure-State-Response (PSR) framework and uses a hybrid model with the entropy weight method and matter-element extension to evaluate China’s ecological environment quality from 2016 to 2020. The results show the overall ecological environment quality evaluation level in China is continuously improved. The results also show that China should pay much attention to the four main factors, which are population density, carbon emissions, per capita energy consumption, and per capita arable land, it should take some policies to improve the four factors. The case study has proven the effectiveness and practicality of the hybrid method and the comprehensive evaluation index system.
基于熵和物元可拓模型的生态环境质量综合评价方法
随着人口和能源使用量的不断增长,中国的生态环境面临着更大的压力。中国更加注重改善生态环境质量与生态文明发展相适应的形势。关键是要构建科学合理的生态环境质量综合评价指标体系。基于压力状态响应(PSR)框架,建立了生态环境质量综合评价指标体系,并采用熵权法和物元扩展的混合模型对2016年至2020年中国生态环境质量进行了评价。结果表明,我国生态环境质量综合评价水平不断提高。研究结果还表明,中国应该重视人口密度、碳排放、人均能源消耗和人均耕地这四个主要因素,并采取一些政策来改善这四个因素。案例研究证明了混合方法和综合评价指标体系的有效性和实用性。
