摘　　要：我国对国土空间进行主体功能分区,识别适宜开发和需要保护的区域单元,对协调人与自然的关系、实现可持续发展意义重大。位于中国西部的甘肃省地域跨度大,地理要素在空间上的组合复杂多样,经济发展与生态保护的矛盾突出。利用反映资源环境承载能力、已有开发密度和区域发展潜力的9项综合性指标,以省内83个县级行政区为评价单元,应用因子分析方法,可分为开发类、中间类和保护类三种主体功能类型,分别对应重点开发区、限制开发区和禁止开发区。空间分析显示,甘肃地域分异特征明显,评价单元之间存在着空间自相关性和异质性,功能组团在空间上呈现梯级变化的圈层结构。这为甘肃形成有特色的区域发展格局提供了科学依据。It is essential to divide the Main Functional Regions of territory space and identify the region units suitable for development or in need of protection in China for coordinating the relationship between human and nature and achieving sustainable development.Gansu province,located in the northwest of China,has large geospatial span,complicated and diverse spatial combination of geographical elements,and obvious contradictions between economic development and ecological protection.Employing nine aggregate indices that can reflect the carrying capacity of resource and environment,development density and potential of a region,we evaluate 83 county-level administrative districts in Gansu province with factor analysis method,and divide them into three main functional types： the development type,the middle type and the protection type,corresponding to key development region,restricted development region and prohibited region respectively.Spatial analysis shows that regional differentiation characteristics are obvious in Gansu,there are spatial autocorrelation and heterogeneity among the 83 evaluation units,and functional groups present the spheres structure of ladder changes spatially.This research provides a scientific basis for forming a distinctive pattern of regional development of Gansu province.
