中文摘要：
从控制排水、灌溉-排水-湿地系统、排水再利用、农田非点源污染控制四个方面总结了国内外在减缓农田水环境污染方面的农田排水研究新进展,介绍了控制排水等各项研究的技术方法、减轻化学物质流失的效果及影响因素,提出控制水位对农田化学物质流失的影响及对提高农田水分利用效率的作用、适应于农田排水的人工湿地系统、排水再利用的灌溉模式及相应的控制结构形式、农田非点源污染的综合调控措施等应成为今后减少农田排水对水环境产生负面影响的主要研究内容。
英文摘要：
The advancement of study on farmland drainage technology from the view point of water environment protection is summarized from four aspects,including the control of drainage,establishment of irrigation-drainage-wetland system,reuse of drainage water and control of agricultural non-point source pollution.The new technology of drainage control is presented and the factors affecting the effect of alleviating chemical material pollution are analyzed.It is suggested that the method for controlling the water level in farm land to reduce the nutrient losses,elevating the efficiency of water utilization,effect of artificial wetland,new irrigation pattern and relevant engineering structure mode for drainage reuse and comprehensive measures for controlling the agricultural non-point source are the main topics for research at present.
