摘要
以派河流域气象资料和流域基础信息为基础数据,采用频率分析法和小流域经验公式法推算了派河降雨与径流量的相应关系;结合流域特征,应用产流理论探索了区域降水与派河径流之间的关系;根据湿地污染物拦截的最佳水力停留时间,计算达到各河段最佳污染物拦截效果所需增加的水力停留时间。建议派河流域加强岸边带湿地保护,提高污染物拦截效率。
Based on meteorological data and basic information of the Pai River Basin,frequency analysis method and small watershed empirical formula method were used to calculate the corresponding relationship between rainfall and runoff in the Pai River Basin.Combined with the characteristics of river basin,the relationship between regional precipitation and Pai River runoff was explored by applying the theory of runoff production.According to the optimal retention time of wetland pollutants,the increased hydraulic retention time needed to achieve the optimal pollutant retention effect in each river section was calculated.It was suggested that the protection of the riparian zone wetland should be strengthened to improve the efficiency of pollutant interception.
