【摘要】：【目的】探索湿热岩溶山区县级小尺度生态经济功能区划方法,为其生态经济建设提供理论支持和决策参考,也为湿热岩溶山区生态经济功能区划提供借鉴方法。【方法】以广西大新县为例,在实地调查研究基础上,对湿热岩溶山区县级生态经济功能区划尺度和背景因素的特殊性问题进行分析,把握区划的特殊性和具体要求,从而确定区划的思路与方法。【结果】岩溶山区县级生态经济功能区划等级体系以两个等级为宜,可取行政村级边界作为划分边界;划分指标筛选重点考虑湿热岩溶山区特殊的背景因素,遵照发生历史一致性原则,使用主导标志法,自上而下划分。广西大新县可划分为5个生态经济功能区,下含10个生态经济功能亚区。同时,基于地形起伏度,核算各区人口承载力,并结合各区特征,提出各区发展方向。【结论】研究建立的湿热岩溶山区县级小尺度生态经济功能区划方法具有较强的针对性和可操作性,对相应区域生态经济建设具有一定的指导意义和应用价值。
[Abstract]:[objective] to explore the method of ecoeconomic function regionalization at county level in humid and hot karst mountain area, and to provide theoretical support and decision reference for its ecological and economic construction. It also provides a reference method for ecologic and economic functional regionalization in humid and hot karst mountainous areas. [methods] taking Daxin County in Guangxi as an example, based on field investigation and research. This paper analyzes the particularity of the scale and background factors of the ecological-economic functional regionalization of the county level in the humid and hot karst mountainous areas, and grasps the particularity and specific requirements of the regionalization. [results] the grade system of ecological-economic functional regionalization at county level in karst mountainous areas is suitable for two grades, and the administrative village level boundary should be taken as the dividing boundary. According to the principle of historical consistency and the principle of historical consistency, Daxin County of Guangxi can be divided into 5 ecological and economic functional areas. At the same time, based on the topographic fluctuation, the population carrying capacity of each district is calculated and combined with the characteristics of each district. [conclusion] the method of small scale ecologic and economic functional regionalization at county level in humid and hot karst mountain area has strong pertinence and maneuverability. It has certain guiding significance and application value to the corresponding region ecological economy construction.
