采用截断面内缩尺单元建模的地下水渗透分析

Analysis of Groundwater Infiltration Based on Cut Surface Reduced Scale Modeling

地下水是支撑人类正常生活所需水资源的最重要途径,对地下水资源建模分析的难点在于无法对地下水模型进行精确建模,传统的地下水模型分析方法采用一个年度内的统计测量结果,但地下水受地理因素、季节和月份影响较大,传统方法的分析结果不具有典型代表性。采用基于截断面内设置缩尺单元建模分析的方法,在对地下水的补给、径流、排泄进行分析的基础上,以内蒙古典型地带特征为研究对象,分析了不同月份下,漫滩、平地、山地、洼地等不同地形特征的地下水渗透特性,给出统计结果下的地下水分布,对研究内蒙古地下水具有一定的指导意义。

Groundwater was the most important way for supporting normal human life, the difficulty of the groundwater re-source modeling analysis was building accurate modeling for the groundwater, a statistical model to analyze groundwater measurement result within a year was used in the traditional method, but the groundwater was affected by geographical fac-tors, season and month, so the result of the analysis for the traditional method did not have a typical representative. An groundwater infiltration analysis method based on reduced scale modeling setting in the cut surface was proposed, on the basis of analysis for groundwater recharge, runoff, drainage, the characteristics of a typical zone in Inner Mongolia was tak-en for study, under different months, floodplains, ground, mountain groundwater infiltration characteristics, depression and other different terrain features, the groundwater characteristic was analyzed, the distribution of groundwater under the statis-tical result is given, it has good guidance for the study of groundwater in Inner Mongolia.
