摘　　要：农田土壤中硝态氮淋洗是氮肥损失的重要途径之一,也是地下水污染的主要来源,因此得到了全世界的广泛关注。分析了影响农田土壤硝态氮淋洗的人为因素和自然因素,并综述了包括氮肥管理、水分管理、填闲作物及轮作、作物品种培育等方面阻控对策研究进展,以期为作物优质高产和环境友好的氮肥综合管理研究提供信息。The nitrate leaching occurred in the field soil is one of the main nitrogen fertilizer losses,and is the main source of the groundwater contamination,hence gets world wide concerns.This paper analyzed the man-induced factors and inartificial factors on this problem.And it also summarized the controlling methods in recent years including：nitrogen fertilizer managements,water usage managements,catch crops and rational rotations,and the cultivation of nitrate efficient crop cultivars.The aim of this review was to provide information for the integrative nitrogen fertilizer managements for both high quality yield and environmental protection.
