水土流失区淤地坝的拦泥减蚀作用及发展前景
- Title:
- Effects of Sediment Reduction and Erosion Control and Development Prospects of Warping Dam in Water and Soil Loss Areas
- Keywords:
- soil and water loss; volume of sediment storage; erosion reduction; warping damrelative; stability of dam system
- 摘要:
- 淤地坝是水土流失地区拦泥、减蚀、增产的措施，不论从单坝、小流域、支流和全流域来看，其拦泥减蚀作用都非常显著。在无定河流域每公顷坝地平均拦泥57150m3，淤地坝的拦泥量约占水保总拦泥量的40%～80%。淤地坝的发展前景是建设坝系相对稳定，在暴雨频率为1.0%～0.5%时，坝地水深不大于0.8m，淹水时间小于7昼夜，如达到此条件，淤地坝即可长期起拦泥减蚀增产的作用，因此坝系相对稳定是沟道发展淤地坝的最终目标，是淤地坝发展的必然结果。
- Abstract:
- As measure for sediment storage,erosion control and grain production increase in water and soil loss areas,warping dams are with significant effects in sediment storage and erosion cotrol by either single dam or dams in small watersheds,tributaries and all basin.The volume of sediment storing in warping dams is makes up 40% to 80% of total sediment reduction by water and soil conservation treatment in Wuding river with average sedimcnt storage of 57 150 m3 in each hectare warping land.The developing prospects for warping dams are the consturction of relative stability of dam system,i.e.water depth is less than 0.8 m and duration for warping land in undated is shorter than 7 days when the storm with frequency of 1%. 0.5% happens,in which conditions the dams will keep their effects in sediment storage,erosion control and production increase for a long term.Therefore,relative stability of warping dam system is the final objective and inevitable outcome of warping dam development in gullies.
