摘要:

综合运用P-S-R模型、熵权TOPSIS模型与障碍度模型等方法,以吉林省限制开发区域为研究对象,分析了2008—2016年吉林省限制开发区域资源环境承载力时空格局特征及其影响因素。结果表明:(1)研究期内吉林省限制开发区域资源环境承载力呈不断下降态势,资源环境承载力状况不尽理想;相反,吉林省限制开发区域资源环境承载力变异系数却逐步提升,区域差异逐渐扩大。(2)吉林省限制开发区域资源环境承载力空间上总体呈现出自西向东不断升高的特点。其中,压力指数空间上呈现中部高、东西两翼低的格局;状态指数则呈现中部低、东西两端高的空间格局;而响应指数东西空间分异特征显著,东部明显高于中、西部地区。(3)农村居民人均纯收入、人均粮食产量、人口密度、工业废水中COD去除率、森林覆盖率、城镇化率是阻碍吉林省限制开发区域资源环境承载力水平提升的关键因素。

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.
