疏勒河流域水化学特征及其保护

在分析疏勒河流域水文特征的基础上,重点对其水化学特征进行了较全面的研究.疏勒河流域河水的化学组成虽不尽相同,但大部分河段阴离子中以HCO-3占优势,阳离子中以Ca2+为主.按照水文地质学的方法,根据水中主要阴、阳离子的浓度,将河水分为重碳酸盐类、硫酸盐类和氯化物类三种类型,但大部分河段属重碳酸盐类.根据取样测试,河水的总矿化度为256 12～413 74mg/L,总硬度为3 37～7 16me/L,河水总碱度为2 62～4 25me/L.同时对疏勒河流域河水中微量元素的含量进行了分析研究,对水质状况进行了评价,提出了水环境保护的意见和措施.

Hydrochemical characteristics in Shule River basin and environment protection

Based on analysis of hydrological characteristics of the Shule River basin, an overall study, focusing on the hydrochemical characteristics of the river basin, is performed. It is concluded that the greater part of the river is dominated with HCO~-_3in anions and Ca~+_2in cations. By use of the conventional hydro-geological method, and by taking the content of major anions and cations in the river water as criteria, the river water is classified into three types, i.e. bicarbonate, sulfate, and chloride, and the tests show that most samples belong to the bicarbonate type. According to the sampling tests, the total degree of mineralization of the river water varies from (256.12mg/L) to (413.74mg/L), the total hardness varies from (3.37me/L) to (7.16me/L), and the total alkalinity varies from (2.62me/L) to (4.25me/L). Besides, the contents of microelements in the river water are investigated, and the water quality is evaluated. Finally, some suggestions are made for protection of the water environment.
