摘要
采用SEBAL模型,基于MODIS遥感数据,计算了石羊河流域2004年植被生长期的蒸散发量,并根据土地利用/覆被数据计算分析了主要生态类型的耗水状况。提出了以维持沿河天然植被为主的"民勤绿洲"发展方案。结果表明,耕地、林地和草地为石羊河流域主要生态类型,各类型的月蒸散发量呈规律性变化,且呈"双峰"分布。
This paper calculates the vegetation evapotranspiration of Shiyang River Basin in the growing season in 2004 by using the SEBAL model with MODIS remote sensing data. And it analyzes the water consumption status of major ecological types based on land use/cover data. Therefore, we propose Minqin Oasis development scheme for protecting natural vegetation along the river. The results show that the monthly evapotranspiration of main ecological types which include arable land, woodland and grassland has regular changes and it appears bimodal distribution.
