【摘要】 为探索灌草丛草地植被生长动态及合理利用途径,对山东省济南市五峰山地区灌草丛草地植被地上生物量、物种多样性以及合理利用状况进行了调查研究。结果表明,草地植被总地上生物量在8月达到最大值,结缕草、野古草、黄背草、荩草为主要优势草地植物,其中结缕草和野古草重要值均高于其它草地植物;草地植被均匀度Pielon指数、多样性指数Simpson和Shannon—Wiener指数生长季内呈递增趋势;2009年草地植被禾本科草类保护指标为151.87g/m2,结缕草、野古草、黄背草和荩草保护指标分别为76.34,59.95,23.37和46.60g/m2。更多还原

【Abstract】 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.更多还原
