A Review of the Development Trend of Restoration Technology for Fragile Mountain Ecosystems

Mountain fragile ecosystems occupy a crucial ecological carrier position in terrestrial ecologicalsystems,and the stable operation of their internal material circulation and energy metabolism maintains regionalecological balance and biological diversity .Ecological restoration technology provides core technical support formaintaining the structural stability and functional perfection of mountain fragile ecosystems,and supports thesustainable development of mountain ecological environments .This paper takes restoration technologies formountain fragile ecosystems as the core research object,systematically sorts out the technical connotation,coretypes,implementation paths and optimization directions of existing ecological restoration technologies .The coreresearch purpose lies in clarifying the evolution logic and application characteristics of various restorationtechnologies,sorting out the complete development context of technical systems,and providing standardizedtechnical references and theoretical support for subsequent ecological restoration practice and technical iterationin mountainous fragile areas .The systematic sorting of technical development context can further promote thestandardized,refined and systematic development of mountain ecological restoration technical systems .
