摘　　要：以2015年春季、夏季、秋季共3期莫莫格湿地的Landsat 8遥感影像为基础,利用大气校正法反演研究区的地表温度;在地表温度反演结果和土地利用数据的基础上,利用ArcGIS软件的空间分析工具进行缓冲区分析、叠加分析和地统计分析,从而完成莫莫格湿地的冷岛效应分析。结果表明,湿地对周边不同土地利用类型的冷岛效应(降温作用)随着离湿地距离的增加而逐渐减弱。湿地对不同土地利用类型的降温作用并不相同,对居住地类型的影响范围在240~540 m,对旱地类型的影响范围在480~660 m;湿地对盐碱地的降温作用比较显著,影响范围在600~660 m。湿地在不同季节对其他土地利用类型降温作用并不相同,在春夏秋3个季节中降温作用由强到弱依次为夏季、秋季、春季。Based on the Landsat 8 image of the Momoge Wetland in the spring,summer and autumn of 2015,land surface temperature was estimated by using atmospheric correction method.We used buffering analysis,overlay analysis and geostatistical analysis in spatial analysis tools of ArcGIS software to complete the cold island effect study of Momoge Wetland based on the remote sensing inversion results and land use data.The results showed the cold island effect of the wetland on different land use types was gradually weakened when the distance from the wetland increased.Wetland had different cooling effects on different land use types.The impact on residence,dryland and saline-alkali land was roughly 240-540 m,480-660 m and 600-660 m,respectively.Wetland has different cooling effects on other land use types in different seasons.In the three seasons of spring,summer and autumn,the cooling effect from strong to weak is summer,autumn and spring.
