摘要
山丘区地下水资源量计算,目前由于观测手段的限制还没有有效的直接计算方法。文中以山丘区流域为例,利用实测水文断面资料,以水文分割法和加里宁试算法为基础,对实例流域的地下水资源量从河川基流量的角度进行了分析计算,求出了测站控制断面的多年平均及不同设计频率下的河川基流量,采用河川基流模数得到全流域的基流量。最后对推求河川基流量的不同计算方法的应用条件和精度差异进行了对比分析,提出了具体使用建议。
The calculation of groundwater amount in the mountainous area has no effective and direct method limited by the existing investigating measures. By using the observed data of hydrological cross section, based on hydrological segmentation method and Kalinin test algorithm, the base flow amount of groundwater resources is calculated in the mountainous area of the watershed, and the base flow amount of the long-term annual average and different design frequencies is calculated, and the whole watershed base flow amount is obtained by the base flow module. Finally the application conditions and accuracy of various calculation methods for the base flow is discussed and some suggestions are put forward.
