平原河网区生态流量阈值研究OA
Study on ecological flow thresholds in plain river network areas——a case study of typical rivers in the Jianghan Plain
生态流量是维系江河湖泊水生态系统的重要保障,而平原河网区水系错综复杂,传统生态流量计算方法适用性较差,开展平原河网区的河流生态流量阈值研究具有重要意义.以湖北省江汉平原典型河流为研究对象,从基本生态、特殊生境以及水环境保护等方面开展平原河网区的生态流量阈值研究,以多样化、动态化的需水过程定义生态流量阈值,结果与实际相符,研究成果可为平原河网区生态流量阈值的确定及应用提供借鉴.
Ecological flow is crucial for sustaining the water ecosystems of rivers and lakes.However,the complex water systems in plain river network areas often pose challenges for traditional ecological flow calculation methods.Therefore,studying the thresholds of ecological flow in plain river network areas holds significant importance.This study focuses on typical rivers in the Jianghan Plain of Hubei Province and investigates ecological flow thresholds in plain river network areas from various perspectives including basic ecology,special habitats,and water environment protection.Diverse and dynamic water demand processes are considered in defining ecological flow thresholds.The results align with reality and provide valuable insights for determining and applying ecological flow thresholds in plain river network areas.
