水土保持措施在水土流失地区，为保护、改良与合理利用水土资源而采用的农业耕作措施、林草措施和工程措施的总称。种类和作用 ①水土保持农业耕作措施包括等高耕作、带状耕作、沟垄耕作，及保留作物残茬、秸杆覆盖、少耕、免耕、砂田等抗旱保墒耕作方法，以达到增加降水入渗、减少土壤水分蒸发和保水、保土、保肥的目的，从而提高作物单位面积产量。②水土保持林草措施有造林种草，封山（沟）育林育草和天然草地改良等。其作用是增加地面植物覆盖，免遭暴雨溅蚀和径流冲刷，改善土壤物理化学性质，同时也为当地人民提供一定的木料、燃料、肥料、饲料或其他林副产品。③水土保持工程措施按其分布的位置和作用可分为：山坡水土保持工程，包括水平梯田、鱼鳞坑、山坡截流沟、水窖、涝池和挡土墙；山沟治理工程包括沟头防护工程、谷坊、拦沙坝、淤地坝、排洪沟、导流堤以及山区小型水利工程等。这些工程措施的作用主要是改变小地形，蓄水保土，排洪防涝，贮水灌溉，除害兴利，为发展农、林、牧业生产创造条件。在一个治理区域内，需要根据不同地块，通过土地适宜性评价，因地制宜地采取不同措施。各种措施不能互相取代，各自具有特有的功能，同时又形成一个有机的整体，以求获得最佳的水土保持效益。措施间的关系 由于中国山区和丘陵区水土流失形式多样；一般人口密度较大，土地利用复杂，因而需要采用多种措施，组成一个综合防治体系，才能有效地制止水土流失。因此要求做到：①根据因地制宜和治理区对粮食生产的要求，选择缓坡，土层深厚(在土石山区)、靠近居民点的地块采取工程措施修建水平梯田，既可蓄水保土、保肥，又是建成稳产高产基本农田的重要途径。在侵蚀沟内，可以修筑谷坊、淤地坝（在黄土区）或营造防冲林，达到蓄洪、拦沙、挂淤、抬高侵蚀基点、稳定沟坡，防治沟蚀的目的。有些沟道还可形成可利用的沟坝地。②在坡度较陡、土壤干旱、瘠薄的荒坡，一般应实行造林种草，根据立地条件（见防护林），可将营造乔木、灌木和种草相结合，或者实行封山育林、育草，以达到增加地面被覆和雨水入渗，涵养水源，调节地表径流，改善小气候，有利于邻近农地的作物生长，形成良好的农林生态系统。③对已有治理设施实行严格的管理，如梯田地埂的维修，幼林的抚育管理等，这样才能取得治理效果。④各种措施间是相辅相成，互相促进的，如通过建设梯田、坝地等基本农田，提高单位面积产量，逐步达到改广种薄收为少种多收，退耕陡坡，实行造林种草，促进林牧业发展，而造林和种草养畜，又为农业提供有机肥料，促进农业高产。就各项措施的水土保持作用而言，也是互相依存和促进的。如山坡水土保持工程蓄水保土，为林草成活、生长创造有利条件，而林草措施又可分散减少地表径流，控制泥沙流失，使措施发挥群体作用。⑤在规划各项治理措施时，必须与改善山区经济状况相结合，充分发挥治理区内自然和社会条件的优势，将配置各项治理措施与发展山区商品生产相结合，例如将林草措施与发展种植业和养殖业相结合，工程措施与发展灌溉相结合。同时，随着人们对提高环境质量的要求，还应考虑所用措施美化环境的效应，在有条件的地区，可与发展旅游事业相结合。
