Abstract:
【Objective/Meaning】Through the evaluation of the ecological environment carrying capacity of Anhui Province and the coordinated analysis of the coupling degree of influencing factors, the characteristics of the ecological environment carrying capacity of Anhui Province were revealed, in order to provide some suggestions for the improvement of the ecological environment carrying capacity of Anhui Province, which was conducive to promoting the ecological civilization construction of Anhui Province. 【Methods/Procedures】According to the connotation and characteristics of ecological environment carrying capacity, by taking Anhui Province as the research object, and based on the DPSIR model, pressure, driving force, state, impact and response were selected to construct the evaluation index system of ecological environment carrying capacity in Anhui Province. Then, the weighted TOPSIS model and the coupling coordination degree model were used to study the temporal evolution of ecological environment carrying capacity and the coupling degree of influencing factors in Anhui Province. 【Results/Conclusions】The results showed that during 2008-2017, the overall
Tj of ecological environment carrying capacity in Anhui Province has increased from 0.2738 in 2008 to 0.6628 in 2017, showing a fluctuating trend, and the grade of comprehensive carrying capacity has realized a fundamental change from poor grade to good grade. From the perspective of subsystems, the close degreee of the five subsystems showed an upward trend of different ranges, among which the pressure subsystem increased from 0.3414 in 2008 to 0.6377 in 2014, and maintained a high and stable trend, with low pressure driving in ecological construction. During the sample period, the coordinated development of ecological environment and economy and society in Anhui Province showed an overall upward trend, especially after 2013, when the growth rate was obvious and the fundamental change from barely coordinated to well-coordinated was realized.
