济南市五峰山地区灌草丛草地植被特征研究
Bulletin of Soil and Water Conservation(2011)
Abstract
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。
