| 英文摘要: |
| Taking Hefei city as the research object, the evaluation index system of ecological carrying capacity was con⁃
structed based on the model of ecological elasticity, ecological support and ecological pressure to determine 27 specific in⁃
dexes. The weight was determined by the entropy weight method, and the evolution characteristics and influencing factors of
urban ecological carrying capacity were explored by the comprehensive index evaluation model, correlation model and ob⁃
stacle degree model. The results show that from 2006 to 2017, the ecological carrying capacity level of Hefei changed from
medium bearing capacity to weak bearing capacity, then increased to high bearing capacity and remained relatively stable.
After 2011, the ecological system tended to develop in a positive direction, the level of ecological elasticity decreased from
low to weak stability, then increased to medium stability, the level of ecological support decreased from medium to weak,
then increased to strong. The ecological pressure level raised from medium to high and then falls to low pressure. The per
capita cultivated land area, SO2 content in the air and GDP growth rate were closely related to the ecological carrying capac⁃
ity. The per capita water resources, the proportion of the second industry in GDP and other seven factors were the barrier
factors of the key indicators of the ecological carrying capacity, and the social progress, environmental pollution and re⁃
source supply were the barrier factors of the ecological carrying capacity. |
