我国江河演变新格局与系统保护治理
New pattern of river evolution and systematic protection and governance in China
摘要
Abstract
Systematic governance is the fundamental principle of water governance practice in China in the new era.In recent decades,influenced by changes of nature and climate and intensive human activities,the process of"quantity-quality-watershed-flow-ecology"has undergone significant changes,especially water and sediment fluxes and their processes,resulting in impact on sources of river and sediment,erosion and sediment deposition in river channels,evolution of riverbed and river regime morphology,changes in relationship between river and lake,slowing down of land formation in estuarine deltas and degradation.The evolution of river presents a new pattern,which poses new challenges to flood control safety,ecological safety and economic development in the coastal regions.Facing the new situation of water governance,it is proposed to get knowledge of changes and development trends of river and sediment,with consideration to integrity of ecosystem and systematicity of river basins,coordinate standards of defining critical threshold system for water and sediment regulation,promote coordinated restoration of"quantity-quality-watershed-flow-ecology",optimize layout of erosion control,synergize water and sediment regulation,build an effective utilization system,protect habitats of estuary,ensure long-term stability of river,and create a foundation for water security in China.关键词
