大气降水渗入系数l_t和有效渗入系数,是岩溶水天然资源评价中重要的水文地质参数。大气降水渗入量的计算是否可靠,一是取决于圈定的补给范围是否合理,二是所用的渗入系数或有效渗入系数是否正确。 所谓渗入系数T_i,是指大气降水渗入量与同期降水量之比值;而有效渗入系数l_e,是指降水渗入量直接转化为地下水的部分的量与同期降水量之比值。因
Atmospheric precipitation infiltration coefficient l_t and effective infiltration coefficient are important hydrogeological parameters in natural resources evaluation of karst water. Is the calculation of the infiltration of atmospheric precipitation reliable, first, depends on whether the delineated supply range is reasonable, and secondly, whether the infiltration coefficient or effective infiltration coefficient used is correct. The so-called infiltration coefficient T_i, refers to the ratio of atmospheric rainfall infiltration and precipitation over the same period; and effective infiltration coefficient l_e, refers to the amount of precipitation directly into groundwater infiltration into the proportion of the amount of precipitation over the same period. because
