【摘要】：河湖水系保持连通是流域内河流与湖泊、河道与河漫滩之间物质流、能量流、信息流和物种流保持畅通的基本条件,也是优化水资源配置战略格局、提高水利保障能力、促进水生态文明建设的有效举措。利用GIS平台和图论理论,研究河湖水系的系统性连通程度定量评价技术,以胶东地区为例,分析了胶东调水东线工程和引黄济青工程实施后山东半岛东部地区水网连通情况。结果表明,胶东调水东线工程实施后连通度可提高50%。此方法可为平原水网区水生态保护与修复、河湖水系连通规划及闸坝调度方案优化等提供技术支持。
[Abstract]:The continuity of river and lake water system is the basic condition of the river and lake in the river basin, the flow of material, energy flow, information flow and the flow of species between river and river beach. It is also an effective measure to optimize the strategic pattern of water resources allocation, improve the water conservation ability and promote the construction of water ecological civilization. The study of the river lake water using the GIS platform and the graph theory theory. Based on the quantitative evaluation of systematic connectivity degree, the connection of water network in the east of Shandong Peninsula after the implementation of the East Route of Jiaodong water diversion project and the Yellow River Diversion Project was analyzed in Jiaodong area. The result shows that the post connectivity of the east line of the Jiaodong water diversion project can be improved by the 50%. method for the protection and restoration of water ecology in the plain water network area. Technical support is provided for river and lake system connectivity planning and gate dam scheduling optimization.
