| 摘 要： | 洪泽湖是江苏省第一大淡水湖，对其周边农业和生态环境具重要意义.LST（地表温度）是区域农业生态环境过程的主要影响因素.本文选择Landsat TM6数据来分析洪泽湖地区地表温度空间差异及其对农业生态环境的影响.首先将TM6数据的DN值转换成亮度温度.在确定了比辐射率、大气透过率和大气平均作用温度之后，就可用单窗算法来计算像元尺度的LST.获得研究区地表温度图像后，接着进行地表温度空间差异分析.结果表明，洪泽湖区陆地与水体温度空间差异明显，而且水体及陆地内部差异同样明显.湿地在水体温度中较低，上游河流注入区水体温度较高.陆地表面温度差异源于地表覆盖类型的差异.

| Abstract: | Hongze Lake is the biggest fresh water body in Jiangsu Province.The Lake has great implication to the agriculture and environment in the surrounding region.LST(land surface temperature) is a key factor shaping impacts on agricultural ecosystem in the region.The purpose of this paper is to use Landsat TM6 data to examine the spatial variation of LST in the region of Hongze Lake.Retrieval of LST from TM6 data is mainly done through so-called mono-window algorithm with estimation of ground emissivity,atmospher... |
