摘要
研究目的:基于全生命周期理念,结合流域生态系统典型特征,提出流域国土空间生态保护修复基本体系、重点任务、实施难点、解决途径及亟待研究方向,为流域国土综合治理提供参考。研究方法:文献综述法,逻辑推理法。研究结果:(1)流域国土空间生态保护修复应以水为核心开展,全生命周期视角下可分为“识水—治水—管水”三个修复阶段。(2)流域国土空间生态保护修复重点任务在于以水梯度为基础开展流域生态系统特征与胁迫识别,以水连通为主线开展“山水林田湖草沙”系统修复以及以水健康为重点实施修复成效评估及可持续监管。(3)生态胁迫的复杂性、修复模式的精准性以及跨区域协同管理的困难性为流域生态修复实施带来了困难。(4)提升流域生态系统监测的精度和广度,注重多要素、多层级协同的修复目标与模式制定,构建生态修复跨区域全周期协同机制等举措可为解决生态修复难点提供可行路径。研究结论:从“识水—治水—管水”全生命周期视角实施流域国土空间生态保护修复,可为流域国土综合治理提供科学借鉴。
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.
