摘要
蒸散发量是水量平衡计算中最为重要的因子之一。利用实地调查、勘察及定位观测等手段,获得典型流域的基础资料,采用CROPWAT模型计算流域实际蒸散发量,以研究流域的水量平衡情况。采用该方法计算好水川流域不同土地利用类型的作物需水量及实际蒸散发量,结果表明:好水川流域全年总缺水量为60.17 mm;5类土地利用类型的缺水量,水域>林地>草地>耕地>居民地;基于CROPWAT模型的水量平衡研究结果可以较好反映当地的实际耗水状况及水量平衡状况。
Evapotranspiration was the most important part in water balance calculation.Through investigation,survey and positioning observation,and other means,basic material of typical watershed was obtained,basin actual evapotranspiration was calculated using CROPWAT model to study the basin water balance situation.The crop water requirement and the actual evapotranspiration of different land types were calculated in Haoshuichuan watershed.The results show that the water total annual water deficit is 60.17 mm in Haoshuichuan watershed;five types of land types of water deficit from big to small are waters,forest land,grassland,cultivated land and residents.The water balance research results based on the CROPWAT model can well reflect the actual water consumption and water balance.
