生态脆弱区社会经济与资源环境耦合协调度研究:以云南省昭通市为例

Coupling coordination degree of socio-economic development with resource and environment in Zhaotong City of Yunan Province as a fragile region

对于生态脆弱地区,探寻其社会经济发展与资源环境的协调发展模式对于实现地区的可持续发展具有重要意义。构建相对资源承载力模型和耦合协调度模型,测算云南省昭通市相对资源人口承载力和经济承载力,并对"经济-资源环境-社会"系统协调发展度进行时空分析。结果表明:1)昭通市相对资源人口承载力超载严重,社会资源承载力低且显著超载;2)相对资源经济承载力处于富余状态,资源的经济价值尚未充分开发;3)昭通市社会经济发展受资源环境制约显著,系统不协调度有拉大趋势。提高第二产业发展水平,优化产业结构是促进昭通市"经济-资源环境-社会"系统协调发展的主要措施。

Exploring a coordinated development pattern between soico-economic development and natural environment has important significance for realizing the regional sustainable development,especially in ecologically fragile regions. In this work,the relative resource carrying capacity model and the coordinated development model were used to analyze the coordinated development level in Zhaotong City of Yunnan Province. The results indicated that economic-resource environmentalsocial system（ E-RE-S） in Zhaotong City was not harmonious. The contradiction resulted mainly from the relatively low carrying capacity in social resources. The economic value of resources has not been fully developed yet. The reason of E-RE-S disorder was the unreasonable structure,especially the low development level of secondary industry.
