凌源市自1980年以来在青龙河和大凌河上共修建6种类型拦河坝35座,经4次特大洪水,石笼坝(15座)大部分被冲毁,浆砌石坝和倒L型坝(共6座)基本完好,装配式面板坝(6座)冲毁5座,翻板闸式和立轴闸式坝(共8座)基本完好。根据引水筑坝和运行实践... 凌源市自1980年以来在青龙河和大凌河上共修建6种类型拦河坝35座,经4次特大洪水,石笼坝(15座)大部分被冲毁,浆砌石坝和倒L型坝(共6座)基本完好,装配式面板坝(6座)冲毁5座,翻板闸式和立轴闸式坝(共8座)基本完好。根据引水筑坝和运行实践,结合河流及水文特性推荐在山区河流修建中小型壅水建筑物采用两端建倒L型式直线型重力坝,中间主河床建闸式坝的组合坝型,它具有经济、安全、防冲、防淤、有利于泄洪和不抬高河床的优点。 展开更多

Presently concepts and methods related to water resources conservation of mountain rivers are seriously insufficient,and its level is far from being adaptable to the development of a harmonious society.As mountain ecosystems play a key role in water resources conservation of mountain rivers,and the characteristics of mountain ecosystems and hydrologic features of mountain river follow strong temporal and spatial distribution,partition theory can be applied to the water resources conservation of mountain river.This theory observes the following partition principles:regional relativity,spatial continuity,integralcounty,meeting management needs,hierarchical principle,and comparability principle.And it lays equal emphasis on both water resources conservation and environmental protection,on both water quality conservation and water quantity protection,on the combination of water features,water cycle and water pollution.In the partition methods,index method and map superposition method will be applied in region partition.The example of region partition of water resources conservation in the upper reaches of the Yangtze River shows that the partition theory is practicable in water resources conservation of mountain rivers,and it provides a platform for future study in water resources conservation. 展开更多
