A Distributed Model of Reference Crop Evapotranspiration Based on the DEM of Shiguanhe River Basin
摘要
Abstract
The spatial distribution of solar radiation is significantly impacted by topography (slope, aspect and terrain inter-shielding) and in turn makes large differences in spatial distribution of reference crop evapotranspiration .Parameters ( vapor pressure, temperature and solar ra-diation) strongly related to topography were adjusted based on the digital elevation model (DEM) of Shiguanhe River Basin, then a distributed model of reference evapotranspiration was established to calculate reference crop evapotranspiration. The results showed that spatial variation of reference crop evapotranspiration is obvious for the reference evapotranspiration and is strongly related to the topography .Solar radiation and reference evapotranspiration in southern slope is bigger than others and in northern slope is smallest.The model is helpful for improving the es-timation of regional reference evapotranspiration, water resources planning and utilization.关键词
