| 摘 要： | 以位于半干旱地区的冀蒙接壤带为研究对象,利用SEBAL模型和邻近研究区10个气象站点的气象数据,反演得到研究区内各种土地覆被/利用类型的日蒸散规律,并与来自张家口市的蒸散数据作了比较,反演得到的蒸散发精度较高.研究结果表明:1)水体、林地蒸散呈现双峰结构,其他土地覆被/利用类型呈现单峰结构;2)研究区域内日蒸散发量的排序是:林地、水体、草地、居民点、未利用地、耕地、沙地.

| Abstract: | Contiguous area in Hebei-Inner Mongolia was selected for this study.SEBAL model combined with Landsat TM5 image and meteorological data from 10 stations near the contiguous area were used to induce daily LUCC evapotranspiration.Compared with evapotranspiration data from Zhangjiakou water bureau,the accuracy of induction was high.These data revealed that evapotranspiration of water and woodland showed double peaks.Daily evapotranspiration was in descending order: woodland,water,grassland,residential point,un... |
