Title: The Effect of Artificially Planted Caragana -Pearshrub Density on Vegetation Characteristics in the Restoration Process of Degenerated Grassland
Abstract: The dynamic changes of vegetation characteristics were analyzed in restoring pearshrub(Caragana)-grassland planted in different plant-density in Eastern Ningxia,There collected 32 families,77 genera,83 species spermatophyte in test section.In pearshrub(Caragana)-grassland of different density,the basic change tendency of species diversity of plant community、coverage of plant communinty and plant biomass is: 10m bandwidth pearshrub(Caragana)-grassland6m bandwidth pearshrub(Caragana)-grassland4m bandwidth pearshrub(Caragana)-grassland,similar to homogeneity index change,and contrary to the ecological dominance change.
