花园水库枢纽工程坝址选择

摘要

In accordance with Planning for 100 Billion jin Grain Production Capability Construction in Heilongjiang Province compiled in 2008,Comprehensive Planning of Songhua River Watershed compiled in April,2010,Brief Introduction of Important Projects in Heilongjiang Province Water Conservancy Development ＂Twelve Five-year Plans＂ Planning compiled in July,2010 and Planning for Construction of 10 Million mu Paddy Fields Added Newly in Heilongjiang Province compiled in 2010,the Huayuan Reservoir was recommended as the important hydraulic engineering complex in the comprehensive regulation of Yalu River watershed in the near term.The total storage of Huayuan Reservoir is 0.372 billion m3 and irrigation area is 0.1313 million hm2.The curves of cost and submerge loss were used to estimate the project costs and investment for submerge compensation for the two dam sites located on the river section in light of the same task of flood control and irrigation.The cost of upper dam site is 311.23million Yuan more than the lower dam site,meanwhile,there exists the problems of partial submerged lands in Inner Mongolia,it is difficult to cooperate the submerge compensation problems over the different provinces,and the lower dam site will be selected at the stage of project proposal.%根据2008年编制的《黑龙江省千亿斤粮食生产能力建设规划》、2010年4月编制的《松花江流域综合规划》、2010年7月编制的《黑龙江省水利发展＂十二五＂规划重点工程项目简介》以及2010年编制的《黑龙江省新增1000万亩水田建设规划》,花园水库均被推荐为近期雅鲁河流域综合治理的重点枢纽工程。花园水库总库容3.72亿m3,灌溉面积13.13万hm2,在河段内两坝址按相同的防洪、灌溉任务,按造价曲线和淹没损失曲线估算工程造价和淹没补偿投资,上坝址比下坝址多31123万元,且存在淹没内蒙部分土地的问题,跨省区协调淹没赔偿问题难度大,项目建议书阶段选定下坝址。
