中文摘要:湖北省水库环库库区多以阶梯式农地为主,农业面源污染已经成为水体污染的重要因素之一,控制农业面源污染成为当务之急。本文以宜昌市点军区王家坝水库为例,通过污染综合指数评价法评价水库水质,15个采样点的污染综合指数为2.95~4.16,平均污染综合指数值为3.55,水体总氮(TN)、总磷(TP)超标严重;同时在阐述农业面源污染的基础之上,论述生态拦截系统的原理及王家坝水库具体技术、措施,包括植物选种、生态壁、生态沟、生态塘等,为生态拦截研究提供一定参考。

Study on the construction technology of the ecological interception system of agricultural non-point source pollution

Abstract:Areas surrounding reservoirs in Hubei province are mainly terraced farmlands.In such areas water pollution has been,to some extent,attributed to agricultural non-point source pollution,the control of which thus turns to be our top priority.This paper takes the Wangjiaba reservoir in Dianjun district of Yichang city as a case study to evaluate its water quality by the comprehensive index of pollution.The results showed that the indexes from the 15 sampling points were 2.95-4.16 with an average of 3.55 and the total nitrogen(TN) and phosphorus(TP) exceed far beyond the current standards.Based on cause analysis of such pollution,we also discussed the principle of ecological interception system and proposed some specific technologies and measures such as planting and constructing ecological wall,ditch and pond for water pollution controlling.
