Evaluation of Restoration Effects in Aeolian Pit Desertified Grassland
摘要
Abstract
This study investigated the interactive relationship between plant community structure and function during the ecological restoration of aeolian pit desertified grassland,aiming to identify the domi-nant factors influencing restoration effects and provid a theoretical basis for optimizing restoration strate-gies.Field surveys were conducted in typical aeolian pit desertified grasslands in Xilingol League and Tongliao City to collect plant community characteristics data.The community importance index,species diversity indices,and functional stability indicators were calculated,and grey relational analysis together with advantage analysis was employed for comprehensive evaluation.The results revealed that,during the restoration process,the influence of plant community function(represented by the importance index)on community structure(represented by species diversity indices)was significantly stronger than the reverse influence of structure on function,indicating a marked asymmetric interaction.The Simpson dominance index and Shannon-Wiener index were the dominant structural factors driving changes in community func-tion,with their relative importance exceeding that of species richness.Community functional stability was found to be highly correlated with species diversity structure.Among all structural factors,the Simpson dominance index and the Shannon-Wiener diversity index exhibited the most prominent correlations with functional stability,underscoring the close intrinsic linkage between structural attributes and stability.These findings collectively suggest that,during the initial restoration phase of sandy grasslands,priority should be given to the rapid enhancement of vegetation coverage and overall ecosystem functioning.By driving structural optimization through functional restoration,the community can be steered toward a suc-cessional trajectory of stabilized structure.关键词
