摘要

正在审查东南亚的运河灌溉系统,以期改善其性能。一些中等规模的系统,其排水,可能支持小型灌溉系统不知道的水和土地开发机构的官员。在决定修改中型系统的水流模式时,计划修改的管理员应该了解是否存在这样的依赖系统。这篇论文表明,相对于没有沟壑的土地,依赖系统更有可能是在被沟壑和局部小而深的山谷切割的缓坡土地上形成的。它还建议,航空照片、卫星图像、地图和政府记录可能无法提供有关系统位置的信息,这些信息应该从农民那里寻求。

Dependent irrigation systems in Southeast Asia: Complication for irrigation performance improvements

Canal irrigation systems in Southeast Asia are being examined with a view to improving their performances. Some systems of medium size may, with their drainage water, be supporting small irrigation systems unknown to officials of water and land development agencies. With a decision to modify the water flow pattern of a medium-size system, the administrators who plan the modifications should learn whether such dependent systems occur. This paper suggests that dependent systems are more likely to have been created on gently sloping land cut by gullies and small, locally deep valleys than on land without such valleys. It also suggests that aerial photographs, satellite images, maps, and government records may not provide information on the locations of the systems, and that such information be sought instead from farmers.
