For further understanding of growth dynamics and reasonable utilization of grassland,an experiment was carried out in shrub-grass vegetation in degradation hilly area of Wufeng Mountain,Ji'nan City of Shandong Province.Above-ground biomass,species diversity,and reasonable use were addressed.Results showed that above-ground biomass of the grassland reached its maximum value in August.Zoysia japonica,Arundinella anomala,Themeda japonica,and Arthraxon hispidus were the dominant grassland species,and the importance values of Zoysia japonica and Arundinella anomala were higher than the other grassland species.Species diversity indices of Pielon,Simpson and Shannon—Wiener were increased with growth time.In 2009,the protective index of gramineae was 151.87 g/m²,and the protective indices of Zoysia japonica,Arundinella anomala,Themeda japonica and Arthraxon hispidus were 76.34,59.95,23.37 and 46.60 g/m²,respectively.
