第二松花江流域平原区浅层地下水脆弱性时变特征分析
Time-varying Characteristics of Shallow Groundwater Vulnerability in the Plain Area of the Second Songhua River Watershed
摘要
Abstract
With the plain area of the second Songhua River watershed as study area,we selected seven indicators including depth of water-table,net recharge,aquifer media,soil media,topography,impact of vadose zone and hydraulic conductivity of the aquifer to evaluate the shallow groundwater vulnerability using DRASTIC index method and to further analyze the influential factors of assessment results.Results suggest that groundwater vulnerability distribution in the study area can be partitioned in space and is in good consistency with landform division,among which river valley plain is of high groundwater vulnerability and high risk of contamination due to shallow groundwater.Moreover,influenced by groundwater table variation and net recharge,the level of groundwater vulnerability in particular area has obvious annual and inter-annual change characteristics;whereas in the whole area,the relative level of groundwater vulnerability is still controlled by landforms pattern.In the assessment of regional groundwater vulnerability,more attention should be paid to the selection of representative time data.关键词
