城市地表水水源地小流域系统保护修复技术模式研究
Studies on systematic technology model for protection and restoration of small watersheds in surface water source of the urban area——a case study of the Mangniu River small watershed at the upstream of Miyun Reservoir
摘要
Abstract
Water source protection is a crucial national strategy for ensuring water security.Miyun Reservoir,a primary surface drinking water source for Beijing,faces risks and pressures due to climate change and human activities.Focusing on the Mangniu River's small watershed upstream of Miyun Reservoir,this study analyzes its basic conditions and existing issues,exploring systematic protection and restoration technical models.The research identifies problems related to water resources,environment,and ecology,particularly total nitrogen concentrations in rivers and reservoirs,and assesses land-based contributions to waterbody nitrogen levels.A technical process is established,encompassing six stages:problem identification,goal setting,accounting analysis,key technologies,protection and restoration,and evaluation feedback.This process traces terrestrial sources of water ecological issues to implement land-use management and comprehensive management.Key technologies proposed include optimizing land use,controlling fertilization and non-point source pollution,managing rural point and non-point source pollution,restoring abandoned mining areas,conserving soil and water in erosion-prone zones,enhancing river connectivity,creating optimal habitats for microbial denitrification,increasing habitat diversity,and implementing reservoir protection and hydraulic regulation.The study analyzes the feasibility of achieving watershed restoration goals,proposing a systematic solution that primarily reduces total nitrogen while enhancing biological and habitat diversity.关键词
