内官—香泉盆地是引洮供水工程的主要灌区,在计算得出该地区水文地质参数的基础上,将该地区分为香泉盆地、卧龙川盆地、内官盆地,计算了引洮供水工程实施前后的地下水资源量,并进行了地下水均衡分析。结果表明:工程实施前,3个盆地地下水的排泄量均大于补给量,均呈负均衡状态;工程实施后,地下水处于正均衡状态,香泉、卧龙川、内官盆地的地下水资源量分别为426.15万、134.67万、699.76万m3/a,近期6 a内官盆地和香泉盆地不会出现土壤次生盐渍化问题,卧龙川盆地出口陆家庄—中庄剖面以南约1.8 km的区域出现不同程度的土壤次生盐渍化问题,分布面积。
內官—香泉盆地是引洮供水工程的主要灌區,在計算得齣該地區水文地質參數的基礎上,將該地區分為香泉盆地、臥龍川盆地、內官盆地,計算瞭引洮供水工程實施前後的地下水資源量,併進行瞭地下水均衡分析。結果錶明:工程實施前,3箇盆地地下水的排洩量均大于補給量,均呈負均衡狀態;工程實施後,地下水處于正均衡狀態,香泉、臥龍川、內官盆地的地下水資源量分彆為426.15萬、134.67萬、699.76萬m3/a,近期6 a內官盆地和香泉盆地不會齣現土壤次生鹽漬化問題,臥龍川盆地齣口陸傢莊—中莊剖麵以南約1.8 km的區域齣現不同程度的土壤次生鹽漬化問題,分佈麵積。

The Neiguan-Xiangquan basin is the main irrigation area of the Taohe River water diversion project. Based on the calculation of hydrogeological parameters,it divided the basin into Xiangquan basin,Wolongchuan basin and Neiguan basin to calculate before and after the Taohe River water diversion project of groundwater resources and analyzed the groundwater balance. The results show that the output of the three basin groundwater area is greater than recharge before the implementation of project,showing negative equilibrium. After implemen-ting the project,the groundwater is in the statement of positive equilibrium. The groundwater resources of Xiangquan,Wolongchuan and Neiguan basins are 4. 2615 million,1. 3467 million and 6. 9976 million m3/a respectively. Neiguan and Xiangquan basin will not have soil secondary salinization problems within recent 6 a. In the south about 1. 8 km area of Lujiazhuang to Zhongzhuang profile of Wolongchuan ba-sin appears different degrees of secondary soil salinization. The distribution area is about 2. 07 km2 .
