北京门头沟区公路裸露坡面植物不同配置模式多样性研究

Study on Diversity of Different Arrangement Models of Highway Exposed Slope in Beijing Mentougou District

对北京门头沟区典型坡面的植物不同配置模式多样性进行分析,研究表明在百花山区,群落物种多样性的排序为D(胡枝子+紫穗槐+马棘+荆条+苜蓿+野菊)>B(苜蓿)>E(刺槐+酸枣+马棘+臭椿)>C(高羊茅+苜蓿+野菊)>A(高羊茅)(5.112>4.321>3.890>3.778>3.671)。不同配置模式植物群落物种多样性的分层测度结果表明,灌草配置的群落物种多样性指数明显高于纯灌木群落和纯草本群落。

This article analcies diversity of different arrangement models on slope of the typical pattern in Beijing Mentougou District, the research indicated that on Baihua Mountain areas, communities of species diversity for the sort D 〉 B （alfalfa） 〉 E 〉 C 〉 A （5.112 〉 4.321 〉 3.890 〉 3.778 〉 3.671）. Species diversity of the different disposition on different arrangement model indicates species diversity index of Shrub - grass - targeted communities is significantly higher than pure bush communities and pure herbal community.
