| 摘 要： | 根据德阳市城市规划区的实际情况,选择含水层厚度、富水性、给水度、降水入渗系数、地下水资源可开采模数等能充分反应研究区地下水系统特征的5个指标,建立地下水水量脆弱性评价指标体系,利用专家评分法获取评价指标权重体系,并用计点系统模型及GIS技术进行研究区地下水水量脆弱性综合性评价。结果显示,地下水水量脆弱性较高和高的分布面积约占全区面积的29.7%,地下水水量保护管理形势较为严峻;发现地下水水量脆弱性在地下水补给区相对较低、在排泄区相对较高。 |

| Abstract: | According to the actual condition of Deyang city,5 indexes like aquifer thickness,water abundance,specific yield,precipitation infiltration coefficient,available groundwater exploitation modulus etc.,which can representative of the study area＇s groundwater system feature has been selected to construct the comprehensive indexes system,the weights of indexes are acquired by expert evaluation method,the point count system model and GIS technology are applied to assess the groundwater quantity comprehensive vulnerability in the study area. The results showed that the high or higher groundwater quantity vulnerability distribution area about 29. 7 % of the whole area,Groundwater quantity protection and management situation is more serious; groundwater quantity vulnerability found in groundwater recharge area is lower,in the discharge zone is higher. |
| Keywords: | Deyang city Groundwater vulnerability Vulnerability of groundwater quantity Point Count System Model GIS |
