摘　　要：分析评价土地利用程度及区域差异,为合理开发利用土地资源、调整土地利用方式、实现区域可持续发展提供科学依据。基于2000年ETM+卫星遥感数据和野外实地调查,采用GIS技术和土地利用程度的综合分析方法,对河北省怀来县的土地利用程度及区域差异进行研究。研究结果表明:怀来县土地利用程度整体处于一个中等偏上水平,全县土地利用程度指数平均为244.75。土地利用程度依地形地貌特征不同,表现出不同的分异特征。土地利用程度高的区域集中于平川区,而南北两山区域土地利用程度较低。土地利用程度最高的乡镇是沙城镇,其次为大黄庄乡,土地利用程度最低的是白龙潭林场和水口山林场。狼山和土木是土地利用程度内部相差最大的两个乡镇,土地利用程度内部差异最小的是水口山林场和白龙潭林场。The purpose of the research is to provide a scientific foundation for rationally developing and using land resources,coordinated land use ways,and realizing regional sustainable development.The land use degrees and regional differences in Huailai county of Heibei Province were researched based on landsat ETM＋ data and on-the-spot investigation by using GIS analysis and synthetic analyzing methods.The result of researches showed that Huailai county is at superior median level in land use degree.The average land use degree in the county is 244.75.It presents different characters according as the topography changes.Regions with Higher land use degrees are mostly in basin and lower regions in maintain regions which are in south and north.The town with the highest land use degrees in the county is Shacheng town and the second is Daihuang town.The region with the lowest land use degrees in the county is Bailongtan forestry station and Shuikoushan forestry station.The region with the biggest difference of land use degrees in the towns occurs in Langshan town and Tumu town,and the region with the lowest differenc of land use degrees in the towns are in Bailongtan forestry station and Shuikoushan forestry station.
