- Abstract:
-
In order to measure the pressure of ecological system, the dynamic variation of ecological footprint, capacity, deficit(surplus)was calculated by using ecological footprint method, and then the indicators of ecological footprint diversity and ecosystem development capacity were introduced to consummate the calculation results. Above all, the equation about ecological deficit and per capita ecological deficit was built by using gray system model GM(1,1)and then the sustainable development of Yancheng City in Jiangsu Province from 2019 to 2028 was predicted. The results showed that water body and arable land account for 64%~72% of ecological footprint between 2005 and 2018 compared with different land types; the ecological carrying capacity only increased 25% in 14 years, far below the ecological footprint; the ecological footprint of Yancheng City was 7.8 times of the ecological carrying capacity in 2018; the ecological footprint diversity kept stable in 14 years, it meant there was no obvious changes in different land types, the ecological economic system kept relatively stable. If the pattern of consumption continues, the ecological deficit of Yancheng City is expected to increase 44.6% in 2028. It is suggested that the realization of regional sustainable development should start from three aspects: reducing ecological footprint, improving ecological carrying capacity and ecological footprint diversity index, so as to improve the utilization rate of resources and develop circular economy.
