Abstract:

Based on the PSR model, the entropy weight TOPSIS model and the obstacle degree model, taking the restricted development zone of Jilin province as the research area, this paper analyzes the spatial-temporal pattern characteristics and the influencing factors of resources and environment carrying capacity in this province from 2008 to 2016. The results indicate that: (1) During the study period, resources and environment carrying capacity in restricted development zone of Jilin showed a gradual downward trend, and the resources and environment carrying capacity was not high. On the contrary, the variation coefficient of resources and environment carrying capacity in the study area continued to increase, and the difference of resources and environment carrying capacity of each county (city, district) gradually expanded. (2) The spatial differentiation of resources and environment carrying capacity in the restricted development zone is generally widening from west to east. In addition, the pressure index is high in the middle and low in the east and west, and the state index is low in the middle and high on both sides, and the response index east-west spatial differentiation is remarkable, and the difference in the east part is obviously higher than that of the central and western parts. (3) The per capita net income of rural residents, per capita food production, population density, removal rate of COD in industrial wastewater, forest coverage and urbanization rate are the key influencing factors that hinder the improvement of resources and environment carrying capacity in the study area.

Key words: resources and environment carrying capacity, spatial-temporal pattern, restricted development zone, Jilin province
