摘　　要：水土资源是农业最根本的物质基础,没有水和土,就没有农业和人类。严重的水土流失不仅流失宝贵的水土资源,而且使土壤肥力大大降低,削弱土地生产潜力,减少农业收入。通过水土保持,可以建立生态环境、水资源和土壤耕作保护体系,做到层层设防,节节拦蓄,控制水土流失,促进农村生态环境向良性循环转化,使水土资源得到有效保护,并为农业发展创造条件。The water and soil resources is the most basic material base of agriculture, if there is no water and soil, there is no agriculture and humanity. Serious soil and water loss is not only drains the precious water and soil resources, but causes the soil fertility greatly to reduce, weakens the land productive potential, and reduces the agricultural income. Through the water and soil conservation, may establish the ecological environment, the water resources and the soil cultivation protection system, achieves sets up defenses in depth, control the water and soil loss, promotes the countryside ecological environment to transform to the positive cycle, enable the water and soil resources get effective protection, and creates the condition for the agricultural development.
