城市区域地下水环境变异的水化学因子分析

Water Chemical Elements Analysis of City Area Groundwater Environment Variation

调用SPSS程序,通过数学方法对城市区域地下水场变异起重要的组份进行提取,以起重要作用的组份最少组合来作为评价地下水变异的指标体系.针对南宁市3个分区中特征点进行初步分析,表明城市区域地下水年变异水平是城市的建设与发展作用的结果.从历史背景下研究城市区域地下水缓慢变异程度及趋势,对城市地下水演化规律的认识及城市区域的水土相互作用分析具有重要的指导意义.

With the development of city construction and the increase of population,the city area groundwater is changed slowly under the human activities. In this paper SPSS program was applied and some important factors was drawn with mathematics method. The combination effects of K,Na,Ca,Mg,Fe, Mn were used as evaluating system of water changes. By analyzing the character of area A（concentrateexp exp oiting groundwater city proper）, area B （scatter-exploiting groundwater city proper）, area C （scatter oiting groundwater suburban）in Nanning shows that the groundwater variation level is the remifica tion of city construction and development. Investigating the extent and the trend of ground alternation from history background has instruction significance to the understanding of groundwater movement discipline. Though different area has different groundwater environment alternation and value index system,the means and methods in this article can be helpful.
