摘要
对延安治沟造地壤中流的形成机理进行了分析,利用壤中流的特征提出了无动力壤中流调节灌溉综合技术体系,通过蓄水池、排洪沟、截水沟、灌排两用渠的修建,合理利用水资源,提高水资源的利用效率,实现涝疏旱灌,防治旱涝以及水土流失等自然灾害;通过田间道路的设置、农田防护林的种植,营造生命廊道,改善区域生态环境。并以延安市南泥湾治沟造地工程项目区为例,介绍了主要的工程措施以及无动力壤中流调节灌溉综合技术体系运行模式在实践中的应用,为治沟造地工程中水资源合理利用提供参考。
The formation mechanism of subsurface flow is analyzed. By using subsurface flow characteristics, irrigation unpowered subsurface flow adjusting irrigation comprehensive technology system has been presented. Through building reservoirs, flood discharge, irrigation and drainage canal, rational utilization of water resources, the utilization efficiency of water resources has been improved, the waterlogging dredge drought irrigation has been realized, drought and flood and soil erosion has been prevented and controlled. Through setting field roads, plant- ing farmland sheherbelts, a corridor of life is created, the regional ecological environment is improved. Nanniwan Town in ~an＇an is as an ex- ample to introduce the main engineering measures and application operating mode of unpowered subsurface flow adjusting irrigation compre- hensive technology system in practice, so as to provide some reference for the rational utilization of water resources in the project of the gully control and land reclamation.
