EVALUATION AND ANALYSIS OF COORDINATED DEVELOPMENT OF ECOLOGICAL ENVIRONMENT AND ECONOMY

Using the coupling coordination model, 26 indexes of ecological environment system and economic system were selected to evaluate the ecological environment and economic coupling of Tianjin from 2003 to 2017. The results show that the overall ecological environment and economic coupling of Tianjin are relatively low, but overall goes to the good direction. We successfully developed a model that could be used for evaluating the carrying capacity of regional ecological environment to social economic development and that could be generalized to other regions. The model can simulate the relationship between socioeconomic and ecological environment, and made the results more intuitive, spatial, and visual. Taking Tianjin as the research area, the results of the evaluation were consistent with the analysis results of the original data characteristics, including the indexes: forest cover, per capita GDP and industrial wastewater discharged. It is consistent with the actual situation in the model.
