摘要: 本文通过小流域径流农业系统的合理布局、最佳结构形式以及防洪、防淤的试验研究。根据坡地径流理论,建立坡地表面径流平衡方程,计算了坡面不同技术处理的多年平均流量。降雨集存系统和保水技术对于改善干旱地区生态环境,加速某些地区的沙漠化综合治理,对封闭农业环境进行人工调控,为干旱地区创造成本低、质量高的新水源等提供科学依据。

Abstract: The proper skeleton and optimal structure of runoff farming system in small basin or valley and the experimental data of the flood-prevent and silt-control are presented. On the basis of the theory of slope runoff, the equation of runoff equilibrium on slope surface is created and the mean dis charge from slopes, which treated by different skills on the surface, is calculated. It is acknowledged that the pool-collecting system of precipitation and water conservation skills provided scientific evidences for improving eco-environment in arid areas, rehabilitating desertified lands, closing agricultural environment to control artificially and for finding new water supplies with lower cost and high quantity in dry land areas.
