利用水资源管理模拟模型研究乌鲁木齐河流域地表水与地下水的转换

STUDIES ON THE EXCHANGE FROM SURFACE WATER TO UNDERGROUND WAFER ON URUMQI RIVER BASIN BY USING ADMINISTRATIVE SIMULATION MODEL OF WATER RESOURCE

位于干旱区的乌鲁木齐河流域，在水资源开发利用中，地表水与地下水发生多次转换。水资源的重复利用率已高达１６７％。对于一个仅有６．３２×１０８ｍ３水资源总量的流域来说，研究地表水的开发调度方式对地下水转换补给的影响是一项非常有意义的工作。本文通过建立地表水与地下水联合利用的模拟模型，经过大量运算，随机地模拟了地表水开发利用过程中地下水资源的补给状况，针对扩大喷滴灌面积，提高渠系有效利用率等具体措施，分析了地表水资源量的增加以及地下水资源量的减少对可利用水资源总量的影响，这对于流域规划及水资源管理等方面有指导意义。

Urumqi river basin locates in the arid region. During the exploitation and use of water resource,the exchange from the surface water to underground water happens more than once. The repeated utilizing rate of .water resource has reached a high level of 167 percent. With regard to a basin which only has total water resource quantity of 632 million cubic meters. It is a very significant work to research the impact of exploitation and management of the surface water on the exchange of underground water supply. This paper has founded the simulation modal to integrate the surface water and underground water. By means of a great deal of calculations,this paper simulates random procedure of exploitation and use of the surface water impact on the situation of underground water supply. In the lght of such concrete measures as enlarging of overhead and drip irrigation areas,enhacing the effective utilization rate of ditch,This paper also analyzes the impact on the increase of surface water resource and the decrease of underground water and the change of the total usable water resource. This paper has a guiding meaning on basin programme and water resource administration.
