Ecological Protection and Restoration of Watershed Territories from a Whole Lifecycle Perspective
The purpose of this study is to develop a foundational framework for the ecological protection and restoration of watershed territories to identify key tasks,address implementation challenges,propose solutions,and outline the promising research directions based on the lifecycle concept and the distinctive characteristics of watershed ecosystems,serving as a reference for integrated river basin management.The research methods include literature review and logical analysis.The research results show that ecological restoration ought to be centered on water and can be delineated into three phases,namely,recognizing,treating and managing water,from a lifecycle perspective.The key tasks include the identification of watershed ecosystem characteristics and challenges,guided by water gradients,and the restoration of the interconnected"mountains,rivers,forests,fields,lakes,grasslands and sands"system,with an emphasis on water health for assessment and sustainable management.The complex ecological challenges,the precision of restoration mode and the difficulties of cross-regional collaborative management impede watershed ecological protection and restoration efforts.However,by enhancing the accuracy and extent of monitoring,emphasizing the multi-factor,multi-level coordination of the restoration objectives and models,and establishing a comprehensive,cross-regional cooperation mechanism for ecological protection and restoration,the viable strategies for effectively addressing restoration challenges are offered.In conclusion,implementing ecological restoration through a lifecycle approach of"recognizing,treating,and managing water"can serve as a scientific paradigm for the comprehensive management of watershed territories.
