渗水管道在非黄灌宜农沙地防护林建设中的应用研究

Application of Seepage-pipeline on Protective Forest Construction in Non-irrigated-by-Yellow-River Arable Sandy Land

乌兰布和沙区渠道灌溉系统受风沙灾害影响十分严重 ,农田灌溉得不到保障 ,防护林的存活和正常生长受到严重制约。渗水管道的应用 ,提高了管道输水效率 ,满足了林木的存活和生长需要 ,增强了渠系抗风沙能力 ,提高了防护林防护效益 。

Windsand disaster in Wulanbuhe Sandy Region seriously influenced the irrigation ditch system. It greatly restricted land irrigation, livability and normal growth of protective forest. Application of seepagepipeline improves efficiency to irrigate, and fulfils the demand for livability and growth of forest, and increases the power of irrigation ditch system to resist windsand disaster, and enhances benefits of protective forest. The study is good for wide spreading in exploitation of sandy land.
