测度区域人类活动对地下水的影响是十分必要的工作,尤其是在耗水量巨大的农耕地区,合理的评测对于未来的水资源开发有着重要的指导价值。本文以建三江分局为例,运用灰色关联分析、Pearson相关系数筛选数据,通过投影寻踪评价计算各个农场最近年份的投影值,最后使用G IS技术将各农场划分为四个等级。结果显示,七星、八五九农场人类活动对地下水影响最大,浓江、洪河、鸭绿河、前哨、二道河农场对地下水影响最小。研究结果揭示了建三江分局地下水分布特征,为当地水资源合理优化配置提供了科学依据。
測度區域人類活動對地下水的影響是十分必要的工作,尤其是在耗水量巨大的農耕地區,閤理的評測對于未來的水資源開髮有著重要的指導價值。本文以建三江分跼為例,運用灰色關聯分析、Pearson相關繫數篩選數據,通過投影尋蹤評價計算各箇農場最近年份的投影值,最後使用G IS技術將各農場劃分為四箇等級。結果顯示,七星、八五九農場人類活動對地下水影響最大,濃江、洪河、鴨綠河、前哨、二道河農場對地下水影響最小。研究結果揭示瞭建三江分跼地下水分佈特徵,為噹地水資源閤理優化配置提供瞭科學依據。

To measure the influence of human activities on groundwater is very necessary ,especially in the huge water consumption agricultural areas ,there will be important guidance value in the future development of water resources for a reasonable evaluation . Based on Jiansanjiang Branch Bureau as an example ,this paper uses grey correlation analysis ,SPSS correlation analysis filter data , through the projection pursuit evaluation to calculate projection values of all the farms in recent years ,the application of GIS technol‐ogy to the farms are divided into four levels .According to the results ,Qixing ,Bawujiu farms have the greatest influence of human activities on the groundwater ,Nongjiang ,Honghe ,Yalvhe ,Qianshao ,Erdaohe Farm have the minimum effects on groundwater . Research results reveal the features of groundwater distribution in Jiansanjiang Branch Bureau ,can provide a scientific basis for local optimization allocation of water resources .
