“廖氏山边沟”是台湾著名水土保持专家廖绵浚博士对美国梯形断面山边沟改良设计而成的一种坡面水土保持工程。具体措施是在坡面上,根据不同坡度每隔一定距离沿等高方向开挖一条浅三角形排水沟,以截短坡长分段截泄迳流、防止冲蚀。此工程措施具有许多优点:第一是配合了植草,水土保持效果良好,并对生态环境有益;第二是山边沟可兼为田间作业道供车辆及农业机械通行,为坡地实行机械化作业的农业现代化经营创造条件;第三,工程简单又能应用推土机开挖、造价低廉、易为群众接受。因此, “Liao Mountain ditch” is a famous soil and water conservation expert Liao Mian-jun of the United States trapezoidal cross-section of the mountain ditch improved design of a slope soil and water conservation project. The specific measures are to excavate a shallow triangular drainage ditch at equal intervals along the slope according to different slopes and cut off the slop flow in truncated slope length to prevent erosion. The engineering measures have many advantages: the first is to cooperate with the grass, water and soil conservation effect is good, and beneficial to the ecological environment; the second is the mountain ditch can be both field operations Road for vehicles and agricultural machinery for the implementation of mechanized slope Agricultural modernization to create conditions; Third, the project can be simple and can use bulldozers excavation, low cost, easy for the masses to accept. therefore,
