基于地表-地下水文过程模拟的农业灌溉开采量估算
Estimation of groundwater withdrawal for agricultural irrigation based on surface-groundwater hydrological simulation
摘要
Abstract
In this st udy, we developed a"Xinanjing"model in balancing water storage of both unsat urated and saturated zones, then quantif ied precipitation recharge, groundwater evaportranspiration, and exchange between river flowand groundwater flow. The model was used to calibrate irrigation amount in terms of both observed flowdischarge and depth to groundwat er ta-ble, and estimated irrigation demand of crops. The established method was further applied in the irrigated area of Shaying River Basin, one of plain areas in Huhai River. The results indicated that our method not only well simulate river flowdischarge and depth to groundwater table, but also reliably estimate variation of groundwater withdrawal and its influence on changes of groundwater table. Estimation of groundwater withdrawal and variation of groundwater level is very valuable for management of groundwater resources.关键词
