摘　　要：结合内陆河流域降雨稀少、干旱缺水的自然条件和造林成活率低、生态工程建设成效不显著的生产现状,通过采取水平阶、鱼鳞坑、开沟和穴状等4种整地方式,在山滩旱地进行了对比试验,总结出了适于内陆河流域干旱半干旱地区宜林荒山荒地造林的不同整地技术。该技术的研究应用,可节水保墒,提高造林成活率,有利于植被恢复。Combined with natural conditions(scarce rainfall and drought and water shortage)in inland river basins and production status(low survival rate of afforestation,insignificant effect of ecological engineering construction),comparative experiments were conducted by adopting four kinds of land preparation methods(level bench,fish scale pit,trenching & hole)in dry land.Different soil preparation techniques which are adapted to plant in barren hills and wasteland in arid and semiarid areas of endorheic river basin were summarized.Application of this technology can save moisture,improve the survival rate and is conducive to vegetation restoration.
