摘　　要：国土空间开发适宜性评价是国土空间规划编制和国土开发战略选择的重要基础。以河南省新蔡县为例,对《资源环境承载能力和国土空间开发适宜性评价指南(试行)》进行改进,构建符合当地特点的评价指标体系,并利用ArcGIS空间分析法、多因素综合评价法进行国土空间开发适宜性评价研究。结果表明:全县生态保护重要性总体不高,没有极重要区,重要区面积仅占3.93%,主要分布在新阳高速、大广高速两侧以及汝河、洪河等地;农业生产适宜性总体较高,适宜面积占80.67%,呈现"西部、北部、东部高,中部、西南部、东南部低"的分布特征;城镇建设适宜性总体较高,适宜面积占77.24%,呈现"中西部和镇区高,东西部边缘低"的分布特征。今后应按照"五带四片、一区多点"的国土开发战略布局,合理安排生态空间、农业空间和城镇空间,促进经济社会高质量发展。Adaptability evaluation of land space development is an important basis for planning land space and selecting development strategy.This paper establishes a localized evaluation index system based on“Guide to adaptability evaluation of resources environmental carrying capacity and land spatial development(trial)”,and evaluates land spatial development adaptability via ArcGIS spatial and multiple factors analysis in Xincai county,Henan province.There is no very important ecological protection area in Xincai county,and the important ecological protection area is 3.93%,which mainly distributes in both sides of Xinyang highway,Daguang highway,Ruhe and Honghe.Agricultural production adaptability is generally high with about 80.67%of the land area,high in the west,north and east,low in the centre,southeast and southwest.Urban construction adaptability is relatively high with about 77.24%of the area,showing high in central-western and urban areas,and low in eastern and western marginal areas.This paper presents suggestions on appropriately planning ecological,agricultural and urban land for a better development of economy and society,based on the land development strategy of“five belts-four zones-one district-multiple points”.
