不同类型控水性建筑物在生态拦截技术中的应用浅析

Application of different water-related engineering in the ecological interception

针对灌区范围内农田径流,排水沟沟体内N、P残留比较严重、天然塘堰湿地受到污染的现象,生态拦截技术作为农业生态补偿手段,对农业非点源污染的控制有着非常重要的意义.本文针对生态拦截型沟渠系统构建中的工程技术部分,介绍了不同级别排水沟渠的生态拦截性控水建筑物的应用类型.

The pollution of natural wetland has been developed for many years, and the ditch water has also been enriched by nitrogen and phosphorus, largely attributing to the farmland runoff within the irrigation area. The approach of ecological interception is considered as a kind of agricultural ecological compensation, which has a remarkably important role in con- trolling the non - point source pollution in agriculture. This study focused on the engineering and technology of the ditch system with regards to ecological interception, and introduced the type of water - related engineering in the different levels of drainage.
