摘　　要：基于1996年、2006年和2016年的Landsat遥感影像,在RS和GIS技术支持下,选取滇中星云湖地区具有坝区、半山区、山区典型性的江城镇、九溪镇、安化乡三个集镇中心地为研究区,遥感解译获得三个时段土地利用状况,分析1996—2016年期间的集镇聚落用地变化特性及其驱动机制.结果表明:研究区聚落用地面积随时间推移在不断增大,聚落规模空间扩张明显;尽管三个典型集镇聚落用地规模大小次序为江城镇>九溪镇>安化乡,即坝区>半山区>山区,但各聚落用地的年平均扩张变化特性则表现为山区>坝区;各典型集镇聚落建设用地时空变化主要受其具体地形自然条件和交通人文社会因素的影响驱动;综合遥感与GIS技术在滇中星云湖流域典型城镇用地变化监测及分析应用,对于深化探讨滇中高原山区人地关系问题具有实际指导作用与科学意义.Based on the Landsat remote sensing images in 1996,2006 and 2016,with the support of RS and GIS technologies,the central areas of three towns—Jiangcheng,Jiuxi and Anhua,which are the typical representatives of dam area,semi-mountain area and mountain area in the Xingyun Lake watershed of central Yunnan Province,were chosen as the research areas. The land use status of three periods was obtained by remote sensing interpretation,and the change characteristics and driving mechanism of the towns＇ settlement land between 1996 and 2016 were analyzed. The results show that： the size of settlement land in the study areas has increased with the passage of time and the spatial expansion of settlement size is obvious. Although the order of settlement size of the three typical towns is Jiangcheng Jiuxi Anhua,that is,dam area semi-mountain area mountain area,the average annual expansion characteristic is mountain area dam area. The spatial and temporal changes for construction land of the settlements in each typical town are mainly driven by the natural conditions of specific topography and the humanities and social factors of transportation. The comprehensive remote sensing and GIS technology for the typical town land use change detection and analysis application in the Xingyun Lake watershed of central Yunnan Province will have practical guidance and scientific significance for deepening the discussion on the human-land relationship in the mountainous area of the Central Yunnan Plateau.
