湖南省生态-经济系统耦合发展探析

从系统论视角出发,剖析了湖南省生态-经济系统内部诸要素及其结构特征,构建评价指标体系;运用定量评价模型,对区域系统的耦合状态进行了分析.结果表明:1996-2006年湖南省综合支撑能力呈对数型上升,而综合消耗水平呈指数型上升,二者演化速度具有非同步性,耦合度呈快速上升趋势,年均增长4.89度;从2008年起将进入过度开发时期,虽然湖南省资源较丰富,但远未具备过度开发型的物质条件;湖南省进入过度开发时期的原因是,在经济增长方式仍然非常落后和产业结构未得到有效调整的情况下,一味突出出口导向型经济,从而导致综合消耗水平发展快速增长.

An approach on the coupling development of regional ecological-economic systems in Hunan Province

From the perspective of system theory,all the elements and their structural characteristics in the regional ecological-economic systems of Hunan province were analyzed,and an evaluation index system was constructed.Quantitative evaluation model was used to analyze the coupling status of the regional systems.The results showed that in 1996-2006,the integrated supporting ability of Hunan Province raised logarithmically,while the integrated consumption level increased exponentially,indicating the non-synchronous development of them.However,the coupling degree increased rapidly,with an average annual increment of 4.89 degrees.From 2008,Hunan Province shall enter the period of over-exploitation.Though the Province has richer resources,it doesn't possess a strong material base of over-exploitation.Therefore,it's needed to modify the economic growth mode and adjust industrial structure,and to overcome the deficiencies in developing export-oriented economy.
