基于农户福祉的黄土高原土石山区退耕还林生态经济系统耦合效应——以宁武县为例

The coupling effect of converting farmland into forestland ecological economic system based on the farmers well-being in the earth-rock mountains areas of loess plateau——A case study of Ningwu County

以生态经济系统耦合理论为基础,根据宁武县生态环境特点和当地农户福祉水平,构建了宁武县退耕还林生态经济系统,并对其退耕前后的耦合协调状况进行了分析.结果表明,2001—2011年,宁武县退耕还林生态经济系统中的生态系统综合指数与社会经济系统综合指数均呈增长趋势,而且二者的增长速度几乎是同步的;2001—2006年,宁武县生态系统综合指数的增长率大于社会经济系统综合指数的增长率;而2006—2011年,二者正好相反,说明退耕还林工程对宁武县生态环境的改善具有明显的效果.从总体上看,宁武县生态环境和人类福祉均处于较低的水平.2001—2011年,宁武县退耕还林生态经济系统的耦合协调状况得到逐步改善,由退耕前的勉强协调发展类福祉和生态同步型过渡到基本协调发展类福祉和生态同步型.

According to the local geographical conditions , the characteristics of the natural ecological environment and social‐economic development level ,this paper chose Ningwu County in northwest Shanxi Province as the research object and constructed the coupled ecological economic systems of converting farmland into forests by the coupling coordinative degree systems , and analyzed the process and mechanism of the influence of converting farmland into forests on farmers well‐being . The results suggested that , from 2001 to 2011 , the ecological environment comprehensive index and farmers well‐being comprehensive index both gradually increase with almost same grow th rate . From 2001 to 2006 , the ecological environment comprehensive index is bigger than the latter , and on the contrary , from 2006 to 2011 ,the latter is bigger than the former .On the whole ,ecological environment and farmers well‐being＆nbsp;in Ningwu County are in a lower level . The coupling coordination of the compound ecological economic system is gradually improved ,which gradually transforms from synchronous type of reluctant coordination development with well‐being and ecology to synchronous type of primary coordination development with w ell‐being and ecology .
