Species Diversity Characteristics of Vegetation Restoration in Mining Sites in the Taihang Mountains of Southern Hebei Province
This article adopted the method of field plot investigation to analyze the composition of vegeta-tion community structure and species diversity characteristics under different restoration modes.The research results indicated that the artificial restoration mode(Forsythia suspensa)contained a total of 17 species,be-longing to 10 families and 17 genera,the natural restoration mode(CK)contained 15 species,belonging to 9 families and 15 genera,and the natural background(BK)contained 11 species,belonging to 7 families and 10 genera.Both Artemisia tanacetifolia and Cleistogenes chinensis appeared in3 treatment types simultaneously.The relative importance values of Artemisia tanacetifolia were BK>CK>Forsythia suspensa,while Cleisto-genes chinensis was Forsythia suspensa>CK>BK.Artemisia tanacetifoli was second only to Phragmites austra-lis in natural community systems that were not affected by mining activities;Hidden grass showed a gradually in-creasing trend in the order of BK,CK,and Forsythia suspensa.The richness,diversity,and evenness all showed that the Forsythia suspensa pattern was higher than natural restoration,and then higher than undisturbed natural background areas.By artificially introducing locally adapted species such as Forsythia suspensa,the succession process and restoration situation can be significantly improved in a relatively short period of time.
