基于国土功能导向的鹤壁市资源环境承载力评价及其空间分异研究

Research on evaluation and spatial differentiation of resource environment carrying capacity in Hebi city based on land function orientation

开展市县级资源环境承载力空间格局分析,可以指导区域国土空间布局。在分析国土空间功能、资源流动特点的基础上构建市县级资源环境承载力评价指标体系,通过GIS空间分析法研究鹤壁市3种视角下的资源环境承载力空间格局分异特征。结果表明:鹤壁市3种视角下的资源环境承载力空间分异特征明显,生态视角下的资源环境高承载力区域主要分布在鹤壁市西部,农耕视角下的资源环境高承载力区域主要分布在鹤壁市中部和东部,城建视角下的资源环境较高承载力区域主要分布在鹤壁市东北部、中部等;农耕视角下的资源环境高承载力区域全域占比最大,达到56.02%,面积达到1199.11 km^(2);鹤壁市3种视角下的资源环境承载力存在显著的空间正相关性,3种视角下的资源环境承载力空间聚类特征和热点分布差异明显。

The analysis of the spatial pattern of resource environmental carrying capacity(RECC)at city and county level can guide the optimization of regional land space layout.Based on the analysis of land spatial function and the characteristics of resource flow,the evaluation index system of resource environmental carrying capacity at city and county level was constructed,and the spatial pattern differentiation characteristics of resources and environment carrying capacity in Hebi city from three perspectives were studied by GIS spatial analysis method.The results showed that the spatial differentiation characteristics of resource environmental carrying capacity in Hebi city were obvious.The areas with high level of RECC from the perspective of ecology were mainly distributed in the western part of Hebi.The areas with high level of RECC from the perspective of agriculture were mainly distributed in central and eastern part of Hebi.The areas with high level of RECC from the perspective of the city construction were mainly distributed in central and northeast part of Hebi.The regional proportion with high level of RECC from the perspective of agriculture was the largest,accounted for 56.02%,with an area of 1199.11 km^(2).There was a significant spatial positive correlation among the three perspectives of resource environmental carrying capacity in Hebi,and the spatial clustering characteristics and hot spots distribution of the three perspectives were significantly different.
