摘要
综述了近年来国内外稻田水分渗漏的研究现状,并对渗漏的成因(如土壤特性、田间水力特性、作物自身因素及田间管理等)进行了分析,指出当前水分渗漏监测研究在实际应用中还存在一定的问题,必须在加强单个测点监测研究的同时,开发精确可靠的区域或更大尺度的理论模型及地-空综合研究手段,以实现区域尺度稻田水分管理的自动化,并为节约用水打好坚实基础。
The research status and causes （soil properties,field hydraulic properties,plant factors and field managements ） of water percolation in paddy field at home and abroad in recent years was sum up.It’s pointed out that there still existed some problems in monitoring percolation in paddy field in the practical application.Not only the single points monitoring should be emphasized,but the studying at the regional or even more bigger scales should be also improved based on advancing more accurate and reliable theory models and the land surface-space comprehensive studying approaches to realize the automatization of water management in paddy field at the regional scale and to build a solid basis for water saving.
