安徽省“三生”功能空间特征及分区调控

Spatial characteristics and zoning regulation of"production-living-ecological"functions in Anhui

本文基于“三生”功能评价体系,借助空间自相关、耦合度、障碍诊断模型分析安徽省“三生”功能的空间特征和划分空间类型,识别不同空间区域的障碍功能并提出相应调控对策。结果表明:(1)安徽省“三生”功能数量结构分别呈现纺锤体等级分布、金字塔等级分布和锥形瓶等级分布;生产功能空间分布呈北高南低,生活功能空间分布较为分散,生态功能空间分布呈北低南高。(2)生产功能冷点区到热点区在空间上呈现出由南到北过渡式的分布格局;生活功能在空间上呈现出中间高、四周低的凸字形分布格局;生态功能冷点区到热点区在空间上呈现出由北到南过渡式的分布格局。(3)将安徽省分为优先改善区、重点改善区、潜在改善区、协同提升区、潜在提升区和适度优化区等6种区域。

On the basis of"production-living-ecological"functions evaluation system,this paper analyzes the spatial characteristics and classifies the spatial types of"production-living-ecological"functions in Anhui with the help of spatial autocorrelation,coordination degree and obstacle diagnosis model.It identifies the obstacle functions of different spatial areas and proposes corresponding control measures.The results are as follows:(1)The quantitative structures of the"production-living-ecological"functions in Anhui has three types-spindle-shape grade,pyramid-shape grade and conical bottle-shape grade.The spatial distribution of production function is high in the north and low in the south,the spatial distribution of living function is scattered,and the spatial distribution of ecological function is low in the north and high in the south.(2)The spatial distribution of production function from cold spots to hot spots shows a transitional pattern from south to north;the spatial distribution of living function shows a convex pattern of high in the middle and low around;the spatial distribution of ecological function from cold spots to hot spots shows a transitional pattern from north to south.(3)Anhui can be divided into six zones:including priority improvement zone,key improvement zone,potential improvement zone,synergistic improvement zone,potential improvement zone and moderate optimization zone.
