山东茶山植物群落结构及物种多样性

Community Structure and Species Diversity in Tea Mountain of Shandong Province

茶山地处鲁东南地区,为全面了解其植物群落结构及物种多样性,2006年7月和10月对茶山植物群落结构及物种多样性进行野外调查,记录到高等植物352种,隶属90科250属,获得标准样方11个,面积6 600 m2。样方数据显示,该区域乔木种类匮乏,乔木层平均物种数2.55,Shannon-Wiener指数平均值0.48;灌木层平均物种数10.55,Shannon-Wiener指数平均值1.68。该区域受人为干扰影响显著,正处于群落演替早期,物种多样性偏低。

Mountain Tea is located in the southeast of Shandong province.To fully understand community structure and species diversity of Tea Mountain,the authors conducted a field survey in July and October of 2006.They recorded 352 higher plants,belonging to 250 genera and 90 families,and obtained 11 standard samples with a total area of 6 600 m^2.The data of samples indicated that the tree type was deficient in that region,the average species of tree layer was 2.55,and the average index of Shannon-Wiener diversity was 0.48; the average species of shrub layer was 10,55, and the average index of Shannon-Wiener diversity was 1.68. Mountain Tea was being in the remarkable jamming iniluence, that region was in the initial stage of commnnity succession, and the species diversity was low.
