广东省西江流域国土绿化示范项目示范效应与实施路径研究OA

The forest resources and identified regional ecological problems of the Xijiang Watershed were analyzed.A accurate forest quality improvement measures such as artificial afforestation,degraded forest remediation and restoration,and forest tending were proposed.By establishing four demonstration models including restoration of South subtropical forest communities,cultivation of large-diameter timber stand of precious tree species,the prevention and control of pine wilt disease,and enhancement of forest quality,it aims to build replicable and promotable typical examples for"Green and Beautiful Guangdong"ecological initiative and"quality improvement-oriented"land afforestation in the southern regions of China.To promote the high-quality implementation of the Central Government's land greening demonstration project in the Xijiang Watershed,four implementation approach have been proposed:advancing the construction of large-area forest patches according to the"one belt,five corridors,and three zones"layout,formulating corresponding ecological restoration measures based on forest stand characteristics,scientifically selecting and configuring tree species to achieve greening,coloration,and preciousness,and optimizing project implementation management to achieve full-process closed-loop supervision.
