该项目应用近自然修复理论,以解决梯田地埂重力侵蚀、道路水土流失、防护林树种单一和功能退化、人工草场二次垦殖、经济林水保效益差等目前水土保持存在的主要技术问题为突破口,把山区土地划分为“经济开发地”和“环境保护地”两大类型进行接近自然的复式配置,设计出“地埂接近自然休止角的农果草梯田复式生态经济技术系统、适土适树复式防护林技术系统、林(果)草水相结合防止生产道路侵蚀与集水窖灌的复式道路技术系统”进行了6年试验示范,得出适合黄土丘陵区的近自然水土保持技术体系模型,为黄土丘陵区治理水土流失和山川秀美建设提供了技术样板。
This project uses the near-natural restoration theory to solve the major technical problems of soil and water conservation, such as gravity erosion of terraced fields, soil and water loss of roads, single and degraded shelterbelts, secondary reclamation of artificial grasslands and poor economic benefits of water and soil conservation. As a breakthrough point, The land in mountainous area is divided into two types of “economic development” and “environmental protection land” to carry out the close-to-nature compound configuration and design the agro-terraced compound eco-economic technology system , Suitable soil suitable tree multi-shelter forest technology system, forest (fruit) grass and water combined to prevent the production of road erosion and catchment irrigation compound road technical system "for 6 years of experimental demonstration, come to the suitable loess hilly region near nature Soil and water conservation technology system model for the loess hilly area to control soil erosion and beautiful mountains and rivers to provide a technical model.
