【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。更多还原

【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.更多还原
