农田排水沟渠的生态环境效应研究综述

农田排水沟渠是农业生态系统中的重要组成部分,随着研究的深入,农田排水沟渠的生态环境效应逐渐得到大家的关注。该文从水文效应、生物效应和去污效应等方面归纳了目前国内外农田排水沟渠的研究进展,重点阐述了农田排水沟渠与农田地下水位、生物多样性和去除氮磷等营养物质的机制,同时简要介绍了沟渠模型和管理方面的研究,结合目前研究状况,提出今后尚需进一步研究的问题,以期为农田排水沟渠生态环境效应的研究提供参考。

A Review on Ecological and Environmental Effects of Agricultural Land Drainage Ditches

Agricultural land drainage ditches is an important part of the agro-ecosystems, with the further research, ecological and environmental effects of agricultural land drainage ditches are gradually focused. This paper reviewed the research advances in the effect of agricultural land drainage ditches on hydrological and eco-environment at home and abroad, and explained explicitly the mechanism of between agricultural drainage ditches and agricultural groundwater level and biodiversity, and the removal of nutrients such as nitrogen and phosphorus;Additionally,it introduced the advance in ditch modeling and ditch management study, further researches needed in the future were put forward in the light of current research conditions, in order to provide the reference for the study of the ecological and environmental effects of agricuhnral land drainage ditches.
