综合运用Landsat数据、Quickbird数据、Modis数据、适时气象数据等资料，通过有效的数据筛选；在ERDAS中建立单窗算法模型提取地表温度；分别以盘龙江、翠湖-圆通山区域为中心，研究昆明市主城区主要休憩区对热环境的抑制特征。结果表明：2000年，城郊各地类对城区地表高温抑制作用比较明显；到2008年，市内休憩区对城区地表高温抑制作用比较明显；居住小区内部景观规划对高温抑制起到了积极作用；主城区的水体、绿地对高温抑制作用明显，盘龙江对LST高温抑制半径约为240 m，翠湖-圆通山对LST高温抑制半径约为420 m。

This paper used Quickbird data , Landsat TM/ETM+data, Modis data and the timely meteorological data to built Single-Window Algorithm for extracting the land surface temperature ( LST) in ERDAS.The thermal environment resistance characters of recreation area in Kunming was analyzed by taking the Panlong River and the Green Lake -Yuantong Mountain as the center .The re-sults showed that all kinds of suburban land classes had obvious effect for land surface high temperature resistance in 2000, but rec-reation area played an important role in higher land surface temperature resistance in 2008.The detailed landscape planning within residential area played an active role in resisting higher land surface temperature .The resistance radius of the Panlong River to high-er temperature was about 240m and the Green Lake-Yuantong Mountain was about 420m.
