EVALUATION OF ECOLOGICAL CIVILIZATION IN MEGACITIES

General Secretary Xi Jinping clearly pointed out in the report of the Nineteenth Party Congress that speeding up the reform of ecological civilization system and building ecological civilization are the millennium plan for the sustainable development of the Chinese nation. The ecological problems of mega-cities are related to the sustainable development of economy and society. Because the radiation area of mega-cities is relatively wide, the geographical environment of various city regions is different, and so is the functional orientation, the selection of evaluation criteria and evaluation indicators is particularly important in the evaluation process. Based on the perspective of mega-city functional areas and combining it with the urban development planning of Beijing, this paper discusses the evaluation of ecological civilization in mega-cities, constructs the evaluation index system of ecological civilization index, and uses the coefficient of variation method of objective empowerment method to determine the index weight, and evaluates the ecological civilization of each functional area in Beijing from three aspects: growth quality, ecological protection and air quality. It can be concluded that the index of ecological civilization in Beijing shows an upward trend as a whole, each functional area presents different characteristics, and the implementation of policies has a significant impact on the construction and development of ecological civilization.
