摘　　要：为使新安江模型对岩溶地区尤其是对枯水期退水段的模拟更为精确,对新安江模型自由水蓄水库的地下水部分进行了改进,在原有的一个地下水库基础上再增加一个线性水库以模拟深层地下水的出流过程。实例应用结果表明,改进后的新安江模型对岩溶地区全年日径流的模拟精度略有提高,但对枯水季节退水段的模拟精度提高较大,可供类似地区径流分析借鉴。In order to improve the modeling accuracy in Xin＇Ardiang Model in modeling the recession flow in karst area during dry season, the Xin＇ aniiang model is improved by adding one more linear reservoir in the part of groundwater of the free-water sluice reservoir to simulate the outflow of deep groundwater. Thus there are four more parameters that is f.α1 ,α2 and Akarst for the new groundwater reseroir of the free-water sluice reserior in the improved Xin＇ anjiang model compared with the original Xin＇anjiang model. The new improved Xin＇anjiang model accuracy is increased in simulating the recession flow in karst area during dry season although the model accuracy in simulating the whole year daily runoff in karst area is appreciably increased.
