摘要
地下水脆弱性评价是地下水保护工作的核心内容之一,针对泰安市的特点和区域特色,利用DRASTIC方法,选取地下水位埋深、净补给量、含水层介质类型、土壤介质类型、地形坡度、包气带介质类型以及含水层渗透系数7个参数为评价指标,对该地区的地下水脆弱性进行了定量评价,将泰安市地下水的脆弱性分为脆弱性高、较高、中等和低4个等级,并绘制了地下水脆弱性分区图,对该地区今后制订地下水资源管理、土地利用、环境保护及城市规划等政策措施具有较重要的参考指导作用。
Groundwater vulnerability assessment is the key of groundwater protection.Pointing to characteristics and regional characteristics in Tai＇an city,by using DRASTIC method,selecting 7 parameters as the evaluation indicators,such as groundwater depth,net recharge,aquifer media,soil media types,terrain slope,media types of the vadose zone,and aquifer parameters of hydraulic conductivity,the quantitative evaluation of groundwater vulnerability in this region is carried out,the vulnerability of Tai＇an city is divided into high,relative high,medium and low grades.Division mapping of groundwater vulnerability zoning has been made.It will provide some references for making policies in groundwater resources management,land use,environmental protection and urban planning.
