【摘要】：以甘肃省藏区天祝县为研究对象,将专家咨询、实地调查和实地监测结合,对其水土流失问题进行了分析调查和评价,分生态和生产建设两方面探索适合高寒阴湿地区不同下垫面类型的水土流失治理模式,并提出了治理技术模式:耕地区"免耕种草综合配置技术、青稞油菜与油菜燕麦轮播",林地区"围栏造林+林下植草+高效节灌",草地区"围栏种草+节水灌溉+保水施肥",林草耕地交错区"乔木+灌木+生态草地+简单工程的多生物耦合互补",水蚀冻融侵蚀交错区"防渗+排水植草覆盖",生产建设项目"剥离养护回铺,拦挡苫盖恢复""换填挡护排导,深挖高挡低排""排水、植草为主,拦挡、苫盖为辅,临时、永久结合"。
[Abstract]:Taking Tianzhu County in Tibetan area of Gansu Province as the research object, the paper analyzes and evaluates the soil and water loss problem of Tianzhu County, Gansu Province, by combining expert consultation, field investigation and field monitoring. This paper explores the soil and water loss control model suitable for different underlying surface types in high, cold and wet areas from two aspects of ecology and production construction, and puts forward the control technology model: "No-tillage recommends comprehensive collocation technology" in tillage area. Rotation sowing of highland barley rape and rapeseed oats "," efficient saving irrigation under fenced afforestation forest "," recommendation of water-saving irrigation and fertilization "in grassland area," Arbor irrigation "in interlaced area of forest and grass," Arbor Irrigation and fertilization ", and" Arbor Irrigation, Arbor Irrigation " Multi-biological coupling and complementation of simple engineering of wood ecological grassland, "seepage prevention, drainage and planting grass cover" in crisscross zone of water erosion, freezing and thawing erosion, and production and construction project "stripping and curing and spreading," To restore the "change of filling, retaining, guiding, deep digging, high, and low", "drainage, planting grass as the main, blocking, covering as a supplementary, temporary, permanent integration."
