河长制是以属地管理为主的河湖管理保护创新制度,流域统筹与跨省界联动不足是当前全面推行河长制工作的薄弱环节。以珠江流域典型跨省界河流——东江为例,采用座谈交流、资料收集和实地考察等方式,梳理了东江流域河长制推行现状,系统总结了东江流域跨省界联防联控工作的主要经验与存在的问题,并从加强流域统筹、加快跨省界联防联控制度建设、加强跨省界联合监测、联合执法、信息共享能力等方面,提出了河长制下东江流域跨省界联防联控的政策建议。研究成果可为国内其他跨省流域整体性管理保护提供借鉴。

The river chief system is an institutional innovation for river and lake management and protection based on regional management. Insufficient watershed management and a lack of trans-provincial cooperation are the weaknesses in fully implementing the river chief system. Through discussion and communication, data collection and field research, we sort out the progresses of implementing river chief system in Dongjiang River, a typical trans-provincial river in the Pearl River Basin, and systematically summarize the experiences and lessons learned from the joint protection and management practices. We also put forward some suggestions as follows: promoting river basin coordination, accelerating the construction of trans-provincial joint protection and management systems, strengthening joint monitoring, joint law enforcement, and information sharing capabilities, etc.. The study offers reference for basin integrated protection and management for other trans-provincial rivers in China.
