生态工程背景下我国荒漠草原防风固沙功能研究综述OA

Desert grasslands are an important part of China's northern sand control belt and provide a vital sand-fixation function.As key ecological protection and restoration projects advance,it is vital to elucidate the intrin-sic relationship between plant traits and sand fixation functions for implementing precise measures.This paper summarizes the achievements in vegetation restoration research and sand fixation functional assessment across China's desert grasslands,as well as the requirements for restoring vegetation structure and ecological function within the study region.Focusing on sand fixation in desert grasslands,this paper compares the applicability of varied assessment methods and indicates their ineffectiveness in revealing the impacts of the vegetative communi-ty on sand fixation.Based on the mechanisms by which sand fixation functions affect plant traits,the paper pro-poses directions for functionally improving sand fixation assessment models applicable to areas under ecological restoration projects,thereby providing a reference for decision-making in such major ecological and sand control efforts across China's desert grasslands.
