黄土高原坡耕地水土流失综合治理中循环利用及模式分析

黄土高原地区的坡耕地是水土流失最为严重的区域，治理好坡耕地是防治水土流失的关键。通过对坡耕地水土流失和综合治理主要措施的分析，探讨了黄土高原坡耕地的径流泥沙、坡面水资源以及农业化肥的循环利用．提出了以整治梯田工程、营造经济林、建设集水补水性耕地、实施封禁治理等多种坡耕地综合治理模式。

Recycled utilization and model analysis in water and soil loss comprehensive harness on slope farmland of Loess Plateau

Slope farmland is one of the seriously eroded areas in the Loess Plateau,and control of these areas is essential for the prevention of soil and water loss.Recycled utilization of runoff sediment,slope surface water resources and agricultural chemicals on these slope farmlands is proposed based on analysis on erosion and control measures.Comprehensive control models for restoration are also discussed,such as terraces improvement,forestation,building farmland with water collection and filling facilities,closi...
