云南省小江流域砂化土地整理研究

The Sorting Research of Sandy Land in Xiaojiang Catchment Area of Yunnan Province

云南省小江流域地处小江断裂带,有百余条泥石流沟、造成大量泥沙下泄,使得河床宽敞、土地砂化、边滩发育。多年来东川人一直进行泥石流防治及河滩地开发工作,并取得明显效益。通过全面深入的调查、量测和分析研究,查明了小江滩地利用现状。提出不同类型和气候条件下滩地的种植方向和开发模式,对600多hm2河滩地制定了科学、合理、系统、高效的开发和保护规划。为同类型山区多泥沙河流滩地开发和保护提供借鉴。

Xiaojiang catchment area of Yunnan Province is located in the Xiaojiang rift belt,and has more than a hundred of debris flow ditches resulting in large quantity of sediment let out down,making the river bed spacious,the land turns sand and growth of side beach.For many years, Dongchuang's people have been working on preventing debris flow and developing the experimention of beach,and finally got obvious result.By thorough investigation,survey and study of the present condition of beach used in Xiaojiang,it offered the planting direction and developing model of the beach under different types of the weather,and worked out scientific,reasonable,systematic and efficient development and protection programs.It provides reference for the same kind of mountain area.
