沈阳市2017年地下水枯水期与丰水期水化学类型对比研究

Comparative study on water chemistry types of groundwater dry season and high water period in Shenyang City in 2017

沈阳市属于温带季风性气候,夏季多雨冬季干旱,枯水期和丰水期区别明显,对于地下水水化学类型有较大影响。本文使用阿列金分类法进行评价,得到CⅢCa全年都为绝对优势,丰水期占比较枯水期更大;枯水期与丰水期水化学类型差别较小,说明丰水期降水对于各县区的水化学类型影响较小,反而枯水期地下径流路径更长,溶出更加充分;从各县区看,康平县、法库县丰水期和枯水期水化学类型基本比重没有大的变化,新民市、沈北新区、于洪区、东陵区、辽中区、苏家屯区水化学类型均有一定差异;枯水期和丰水期各县区水化学类型都以Ⅲ型水为主。

Shenyang belongs to the temperate monsoon climate,the summer rainy winter drought,the difference between the dry season and the rainingseason obviously,has a great influence on the groundwater hydrochemical type.In this paper,the evaluation of alemin classification was used to obtain the absolute advantage of CⅢ^Ca throughout the whole year.The mutagenicity and the plentiful hydrochemistry type difference is small,shows the plentiful rainfall for chemical types affected counties districts shows that the mutagenicity of underground runoff path longer instead,stripping more adequately;Look from counties,KangpingandFaku altogether and mutagenicity hydrochemistry type basic proportion in no big change,Xinmin,Shenbei,Yuhong,Donglin,Liaozhongin the north new district,Sujiatunhydrochemical types all have certain difference,Water and chemical types of the counties and districts in the dry season and the raining season are mainly water-based.
