| 摘 要： | 选取黄土高原典型流域罗玉沟流域为研究区,以2006年和1986年两个时段的TM影像为原始数据,通过SEBAL模型估算蒸散量,采用地面实测资料对估算结果进行验证,表明SEBAL模型在该流域较为适用.同时,得到该流域蒸散发的空间变化规律,并结合该流域相应时段的土地利用变化进行对比分析.结果表明:(1)遥感反演日蒸散量平均为...

| Abstract: | the Luoyugou valley was selected as a typical Loess Plateau watershed for this study.The TM image data from 1986 to 2006 was used for calibration and the record from 1954 to 2008 for validation.Through SEBAL model estimating ET;it demonstrates SEBAL model in the basin is more applicable.At the same time,ET spatial variation distribution was gotten over the past 20 years,combined with the corresponding periods of the land-use changes for analysis.The results show as follows:(1) The daily average evapotranspi... |
