摘要:贵州位于长江流域、珠江流域的上游地带,由于特殊的地形地貌,河流共性落差大,水流踹急,水能资源丰富,小水电开发条件好。研究河流所处地区的经济社会条件与自然特性,多方案论证河流开发方案,推荐合理的开发方案指导河流水能资源开发。针对这类问题,作者从工作实践中以黄泥河、蒙江、方村河为例谈几点山区河流水电开发规划的认识。
关键词:黄泥河、方村河、蒙江、装机容量、多年平均发电量
Abstract: guizhou is located in the Yangtze river and the pearl river basin upstream of the region, due to special landform, rivers, common is remote, the water flow tread nasty, rich in hydropower resources, the small hydropower development conditions are good. Research in the region economy river social conditions and natural characteristics, river project demonstration development program, recommend reasonable developing plan river water resources development guidance. Aiming at this kind of problem, the authors from work practice to Yellow River, and find jiang river as an example, FangCun offer some of the hydropower development planning mountainous rivers of understanding.
Keywords: Yellow River, FangCun river, and find river, the installed capacity and years of average turbine

规划认识
经济社发展对河流开发方案的影响
黄泥河发源于云南省曲靖市东山镇,在兴义市乌沙镇成为云、贵两省界河,干流长235km,可利用落差1247m,流域面积8270km2。干流长底至大桥河段河流平缓,耕地资源丰富,人口集中。原规划在大桥河段建设大(2)型水库大桥梯级,利用大库蓄水调节后积能发电。大桥水库正常蓄水位1244m,总库容4.4亿m3,装机容量100MW,淹没耕地12196亩,迁移人口10642人,淹没324国道,移民困难大。由于大桥梯级工程规模较大,受经济社会条件限制,未开工建设。大桥梯级干流上已建长底电站及支流小黄泥河上已建普梯一级、二级电站。这些流域内经济社会条件的变化要求重新论证大桥梯级开发方案的可行性,提出适合河流开发的方案。
大桥河段受上游已建的长底梯级尾水位1199.8m的限制及下游已建老江底梯级正常蓄水位1182m的约束,现状河段可利用水头17.8m。规划河段约束条件还受沪昆高速公路、南昆铁路大桥的限制。……
