摘要
通过连续的野外试验,对北京市重要水源地密云水库水源区曹家路流域的土壤理化特征、面源污染产汇污机制、污染物迁移转化特征等进行了初步分析和研究。研究内容包括:不同土壤类型的理化特征及养分含量随深度的变化规律;一场短时暴雨水文情形下,各面源污染特征指标的变化规律及产汇污机制;不同土地覆盖条件下,流域内各子河段面源污染的变化特征。最后,针对该研究区域面源污染特征,提出了污染物削减及控制的相关对策。
The paper preliminarily analyzes and studies the physical and chemical character of soil,the mechanism of non-point source pollution producing and collecting and the characteristics of transport and conversion of pollutants in Caojialu area which is the source area of Miyun reservoir and the important water source of Beijing through continuous field tests.The outcomes include the physical and chemical character of different types of soil and the law of nutrient content changed along with the depth;the variation law of each non-point pollution index and mechanism of pollution producing and collecting under the condition of a short duration storm and;the variation character of non-point pollution of each sub-river section within the basin under the condition of different land cover.Finally it puts forward related countermeasures for reduction and control of pollutants in accordance with the characteristic of non-point pollution of the studied area.
