A Hybrid Evaluation Method of Ecological Environment Quality Based on Entropy and Matter-Element Extension Model

The ecological environment of China is facing much more pressure with the continuous growth population and energy usage. pays attention to improving quality civilization development in situation. key problem construct a scientific reasonable comprehensive evaluation index system guiding improvement. This paper creates based on Pressure-State-Response (PSR) framework uses hybrid model entropy weight method matter-element extension evaluate China’s from 2016 2020. results show overall level continuously improved. also that should pay four main factors, which are density, carbon emissions, per capita consumption, arable land, it take some policies improve factors. case study has proven effectiveness practicality system.
