我国生态压力与承载力重心动态演变分析
Analysis on dynamic evoluiion of ecological pressure and capacity gravity in China
摘要
Abstract
There is spatial deviation between human ecological pressure and capacity. It is helpful to understand and solve the increasing inter-regional contradiction to study their dynamic relationship. Based on estimating the ecological pressure and capacity each province in China, 1980-2005, this paper has analyzed their temporal-spatial evolution characteristics through calculating two gravity's coordinates, spatial overlapping and changing consistency index. The results show that: (1) the ecological pressure's gravity has fluctuated greatly during 25 years and is guided strongly by population and economic fluctuation; (2) the ecological eapacity's gravity is distributed in the inland areas and far away from ecological pressure's gravity; (3) the spatial deviation between ecological pressure and capacity is an important factor which causes the inequality of the ecological services and regional development.关键词
