河长制为区域性环境保护管理制度,如何在流域层面实现联防联控是当前河长制推行的难点与薄弱环节。以长江流域典型跨省河流——赤水河为例,针对赤水河生态环境保护存在的突出问题,在梳理流域内河长制推行实践的基础上,结合河长制工作的主要任务,总结了赤水河流域保护管理的主要经验与不足;再从推进流域保护整体规划与立法、促进部门联动与联合执法、规范跨界断面监测评估、严格水量分配调度和完善资金投入激励等方面,提出了河长制下赤水河流域联防联控的政策建议。研究成果可为国内其他跨省河流的流域整体性管理保护提供借鉴。

River chief system is a regional management policy for environmental protection. Joint protection and management at basin level is still a challenge and shortage in the implementation of the river chief system. With Chishui River, a representative inter-provincial river in the Changjiang River Basin as an example, we expound the key issues in the eco-environment protection of Chishui River, and make a review on the practices of applying river chief system. On such basis, we summarize the experiences and lessons learned from the protection and management of Chishui River according to the major tasks of river chief system. Moreover, we put forward policy measures for the joint protection and management in the following aspects: promoting the overall planning and legislation for basin comprehensive management, strengthening interdepartmental cooperation and joint law enforcement, standardizing cross-regional sectional monitoring and assessment, tightening basin water allocation and scheduling, and improving financial support and encourage. The present research will provide policy support for basin integrated protection and management for other inter-provincial rivers elsewhere in China.
