摘要： 为了拓展城市用地发展空间，解决城市用地紧张问题，逐步提高低丘缓坡土地为各类建设的供地能力，通过采用级差正规化法和熵值法，研究白银市三县两区低丘缓坡土地开发成建设用地的适宜性程度。结果表明，景泰县和靖远县的低丘缓坡土地建设开发适宜性为高度适宜，平川区和白银区为中度适宜，会宁县为低度适宜。通过研究最终得出景泰县、靖远县、白银区和平川区的低丘缓坡土地开发成建设用地的整体条件较好，适宜性程度较高，在当前条件下适宜开发成建设用地；会宁县低丘缓坡土地现有条件较差，不适宜开发成建设用地，但通过一定的生物措施和工程措施后，可改善区域条件，在未来条件下可进行开发。

Abstract: The purpose of this research is to Provide the basis for solving the problems of shortage of urban land use and improving availability of low hill gentle slope land according to analysis the suitability to converting the mild slop of low mountains and hills to construction land in the tree counties and two districts of Baiyin Area with methods of differential regularization method and entropy method. It showed that, Jingtai County and Jingyuan County were highly suitable to convert the mild slop of low mountains and hills to construction land, and Pingchuan District Baiyin district were the medium suitable and Huining County was the lowest. Therefore, we could draw a conclusion that Jingtai County, Jingyuan County, Baiyin District and Pingchuan District had high suitability and comprehensive conditions to convert the mild slop of low mountains and hills to construction land under current circumstances. Huining County was not suitable to the development, but by taking some biological and engineering measures, Huining County could improved in regional conditions to conduct the converting program.
