摘　　要：以射电望远镜(FAST)项目周边的平塘县、罗甸县为研究区域,利用遥感数据和“3S”技术手段,结合相关统计资料,从土地利用结构系统、土地利用程度系统、土地利用效益系统、土地利用可持续系统4个方面,选取18个指标构建土地利用结构合理度评价指标体系,运用ITOPSIS模型对研究区土地利用结构合理度进行定量评价。结果表明:研究区土地利用结构合理度较低,且存在时空变化差异。2000年、2005年、2013年平均土地利用结构合理度分别为27.45%、29.84%、17.76%,呈先增大后减小波动变化趋势;2000、2005年平塘县土地利用结构合理度均高于罗甸县,2013年略低于罗甸县。Taking Pingtang County and Luodian County around the radio telescope(FAST)as the study area 18 evaluation indexes were screened out by using remote sensing data and“3S”technology,and the data from land use structure system,land use degree system,land use benefit system,and land use sustainable system.The reasonable degree of land use structure was quantitatively evaluated by ITOPSIS model.The results showed the reasonable degree of the land use structure in radio telescope(FAST)surrounding area was very low.There was difference in the spatial-temporal variation.The average land use structure reasonable degree were 27.45%,29.84%and 17.76%,in 2000,2005 and 2013,respectively,showing a trend of increasing at first decreasing later.The land use structure reasonable degree of Pingtang County was higher than that of Luoding County in 2000 and 2005,but was slightly lower than that of Luodian County in 2013.
