摘要
为准确评价区域地下水资源,寻求一种切合实际的河川基流量分割方法,在对查甫沟、黑城沟、昂思多沟设计断面多年平均径流量进行计算的基础上,通过探讨分析河川基流经验斜割法、加里宁试算法两种方法的适用性后,采用直线斜割法进行了多年平均基流量计算和地下水资源评价分析,得出了查甫沟、黑城沟、昂思多沟设计断面多年平均地表径流量分别为387.5万、532.4万、781.2万m^3,多年平均地下水资源量分别为186.8万、256.6万、376.5万m^3,地下水可开采量分别为1 136、733、2 858 m^3/d。
For accurate evaluation of regional groundwater resources,seeking a kind of practical method of river base flow separation,based on the calculation of long?term average discharge of design sections of Chafu gully,Heicheng gully and Angsiduo gully and through the analy?sis on the applicability of the two methods of empirical oblique cutting and Garyning trial algorithms of river base flow,it calculated the nor?mal base flow and evaluated and analyzed the groundwater resources by using straight bevel cutting method.The results show that for the Cha?fu gully,Heicheng gully and Angsiduo gully design sections,the many years average surface water runoffs are 3.875 million m3,5.324 million m3 and 7.812 million m3 respectively;the groundwater resources volumes for many years’average are 1.868 million m^3,2.566 million m^3 and 3.765 million m3 respectively and the allowable exploitation volumes of groundwater resources are 1 136 m3/d,733 m^3/d and 2 858 m^3/d respectively.
