【摘要】:河湖水系保持連通是流域內(nèi)河流與湖泊、河道與河漫灘之間物質(zhì)流、能量流、信息流和物種流保持暢通的基本條件,也是優(yōu)化水資源配置戰(zhàn)略格局、提高水利保障能力、促進(jìn)水生態(tài)文明建設(shè)的有效舉措。利用GIS平臺(tái)和圖論理論,研究河湖水系的系統(tǒng)性連通程度定量評(píng)價(jià)技術(shù),以膠東地區(qū)為例,分析了膠東調(diào)水東線工程和引黃濟(jì)青工程實(shí)施后山東半島東部地區(qū)水網(wǎng)連通情況。結(jié)果表明,膠東調(diào)水東線工程實(shí)施后連通度可提高50%。此方法可為平原水網(wǎng)區(qū)水生態(tài)保護(hù)與修復(fù)、河湖水系連通規(guī)劃及閘壩調(diào)度方案優(yōu)化等提供技術(shù)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.
