吉林省西部资源环境和人口经济发展的耦合性分析

以吉林省西部为研究对象,利用耦合协调模型对其资源环境和人口经济发展的耦合性进行了研究.结果表明,1995-2004年吉林省西部资源环境系统随着降水资源多寡波动性较强.由于内在的脆弱性和人为不合理的开发,资源环境系统发展停滞不前,甚至有降低的趋势.10 a问吉林省西部经济发展迅速,但仍然处于较低水平,并且对农业依赖性较强.由于人口负担较重,人口福利水平没有实质性的改善,人口子系统发展缓慢.总体来看,虽然吉林省西部资源环境和人口经济协调性呈改善趋势,但多数年份属于人口经济滞后的失调类型或人口经济滞后临界失调类型,未来人口经济的发展将会受到资源环境系统较强的限制作用.

Analysis of the Coupling Between Resource-environment and Population-economy in West Jilin Province

By taking the west part of Jilin Province for an example,the coupling coordinate model was employed to analyze coupling interaction between resource-environment and population-economy systems from 1995 to 2004.Analyses indicated that resource-environment system was fluctuated obviously with rainfall and there was a stagnation of resource-environment system owing to the intrinsic frangibility and irrational exploitation.Economy subsystem in West Jilin developed fast in the past 10 years compared with population subsystem.However,economy,with heavy reliance on agriculture,was still lower than other developed regions and human welfare was essentially improved little for undeveloped economy and high human pressure.In general,the coupling coordinate degrees were increased from 1995 to 2004,but most of them belonged to the non-coordinate type or critical non-coordinate type and population-economy lagged behind resource-environment.Resource-environment system may lead to severe restriction to population-economy.
