摘要
畦灌是我国北方地区目前最主要和使用最广泛的灌水方式之一,与其他灌溉技术相比其设施简单、易于运行,但浪费水量是制约该技术持续发展的关键因素。从畦灌的技术要素、水平畦灌技术、畦灌流动模拟3个方面综述了畦灌技术的现状研究进展,并总结了现有研究的不足,指出畦灌技术的发展趋势是畦灌入渗机理的完善、畦灌流动模拟的优化及畦灌技术评价体系的建立。
Border irrigation is the most main and is the most widely used technology in the north of China,comparing with other irrigation technology,it has much advantages,such as the facilities is simple and it is easy to operation,but wasting water is the key limitation for the sustainable development of the technology.This paper reviews the present research results of border irrigation by border irrigation technical factors,horizontal border irrigation technology and border irrigation flow simulation,summarizes the existing limitations of the study,and then points out that the the development trend of border irrigation technology are improving the infiltration mechanism of border irrigation,optimizing border irrigation flow simulation and establishing border irrigation technique evaluation system.
