湖北省农业面源污染防治措施探讨

Discussion on prevention and control Measures of agricultural non-point source pollution in Hubei Province

本文基于湖北省农业面源污染的现状,从“源头控制、过程阻断、末端强化”三个方面阐述面源污染的防治措施。以武汉市江夏区某湖泊为例,定量计算面源污染负荷,通过种植制度优化、化肥减量化等源头控制、设置生态沟渠进行过程阻断、将湖汊改为塘堰湿地等末端强化措施,以达到农业面源污染整治目标。

Based on the current situation of agricultural non-point source pollution in Hubei Province, this paper elaborates the prevention and control measures of non-point source pollution from three aspects: source control, process block and end strengthening. Taking a lake in Jiangxia District of Wuhan as an example, quantitatively calculate the non-point source pollution load, through source control such as optimization of planting system, reduction of fertilizer, setting up ecological ditches to block the process, and transforming lakes into ponds and wetlands. In order to achieve the goal of agricultural non-point source pollution remediation.
