摘要
文章依据三江平原挠力河流域的勘探和观测资料,通过调查分析,根据包气带、水位变动带、岩性、地貌单元、行政单元等,将研究区域划分为4个子区。在此基础上,给出了挠力河流域地下水的几个重要的水文地质参数,即渗透系数、给水度、释水系数、蒸发强度、降水入渗补给系数和灌溉回归入渗系数。这些参数为计算地下水含水量、补给量和水量均衡分析等奠定了基础。
By the exploration and observational data of the Sanjiang Plain Naoli River basin, this paper proposed that the study area should be divided into four subareas according with the investigation and research on the surround air region, water level variation region, lithology, topographic feature unit, and administration unit. On the basis of these data, it offered several important hydrologic parameters of Naoli River basin groundwater, such as permeability quotient, feed water degree, storage coefficient, evaporation intensity, rainfall infiltration coefficient and irrigation regression coefficient. This paper establishes the base for calculating the groundwater water capacity, potential recharge and water balance analysis.
