大庆市区降水偏碱性成因探析

统计分析了2001至2005五年期间大庆市区降水pH值的特征及变化趋势.通过对大气环境质量现状、地表水、地下水和土壤的酸碱度等理化指标监测分析,结合本地区特定气象因素,从几方面论述了降水偏碱性的成因.从环境生态角度出发,运用环境化学中碱度、碱性及相关理论对主要影响大庆市区降水偏碱性的因素,进行分析论证并得出结论,揭示了降水的酸碱性受土壤、水、大气各环境要素的影响,为在干旱和半干旱地区应合理开发利用土壤、植被等自然资源,保护区域生态环境实现可持续发展提供技术服务.

The Analysis of Reason Why the Precipitation is Weak Alkaline in City Proper of Daqing

This paper statistically analyses the characteristics and tendency of PH value about precipitation in city proper of Daqing during the five years from 2001 to 2005. By monitoring and analyzing the acidity, alkalinity and other items about surface water, ground water, soil and atmosphere environment performance, combined with meteorological elements in Daqing areas, the article discusses the reason why the precipitation is weak alkaline from several aspects. From the viewpoint of environment ecology, by using the relavent theory, the treatise analyses the main elements making the precipitation weak alkaline and draw a conclusion that the acidity and alkalinity in precipitation are affected by soil, water and atmosphere, in order to provide technology during reasonably exploiting soil and vegetation in an arid area and a half - arid area, preserving regional ecological environment and realizing the sustainable development.
