摘    要:节水灌溉广义上包括水源开发与优化利用措施、农业耕作栽培、节水技术措施以及节水灌溉技术措施等.这些措施会单独或联合作用而改变影响土壤侵蚀发育的某些因子,从而起到减弱土壤侵蚀、保持水土的作用.笔者从不同的节水措施着手,综述它们对保护、改良及合理利用山丘区水土资源,改变坡面微小地形,增加地面粗糙率和植被覆盖率,拦蓄降水,减缓地表径流,减少土壤冲刷,改良土壤结构,增加土壤抗蚀、渗透、保水性能等方面的作用.

关 键 词:节水灌溉  土壤侵蚀  水土保持

Abstract:As a general,water-saving irrigation includes the development and utilization of water resources,the agricultural water-saving techniques and the water-saving irrigation techniques,etc..Those measures can change some soil erosion factors and take action to the soil and water conservation.Based on the studying of different water-saving measures,we got conclusions that water-saving irrigation can protect and improve and rational use the water and soil resources in mountain and hilly area,change the tiny landf...
Keywords:water-saving irrigation  soil erosion  soil and water conservation
