基于“两山”理论的南疆脆弱区生态与经济系统互动效应分析

Analysis on Interactive Effect of Ecological and Economic System in Fragile Areas of Southern Xinjiang Based on Theory of “Two Mountains”

以南疆生态脆弱区和田地区为例,选取2004—2016年的相关数据,运用"两山"理论及环境与发展互动关系理论揭示了生态与经济系统影响机理。基于生态承载力、生态弹性力、经济开发强度与经济开发速度4个指标构建动态演化模型,分析了各要素间的互动关系。研究发现:①2004—2012年和田地区生态承载力与弹性力均呈上升趋势,具有较强的趋同性,经济开发强度与开发速度上升趋势明显。②生态与经济系统各要素间相互影响和制约,以大量的要素投入为代价带来的经济增长对生态环境产生的抑制作用较强,致使生态系统脆弱性和敏感性日益加剧。依据"两山"理论制定保护和发展规划,推进"绿水青山与金山银山"的协调共生和可持续发展,对有效促进南疆地区的经济发展和生态文明建设具有重要意义。

Taking the Hetian Area of ecologically fragile areas in southern Xinjiang as an examples,this paper selected the relevant data from 2004 to 2016,used the theory of'two mountains' and the theory of interaction between environment and development to reveal the mechanism of ecological and economic system. Based on the four indicators of ecological carrying capacity,ecological elasticity,economic development intensity and economic development speed,a dynamic evolution model was constructed to analyze the interactive relationship between each factor. The results showed that: ①The ecological carrying capacity and elasticity of Hetian Area were on the rise in 2004 to 2012,and with strong convergence,the economic development intensity and speed were on the rise obviously. ②The interaction and restriction between the elements of the ecological and economic system,and the economic growth at the cost of a large number of factors had a strong inhibition on the ecological environment,increasing ecosystem vulnerability and sensitivity. It was of great significance to formulate the protection and development plans based on the theory of'two mountains' and to promote the coordinated symbiosis and sustainable development of'green water and green mountains and Jinshan and Yinshan' in order to effectively promote the economic development and ecological civilization construction in southern Xinjiang.
