通过对湘南21个样地(5 000 km~2)实地调查,应用重要值计算多样性指数Shannon-Wiener(H′)和Simpson指数(D),Pielou均匀度指数(JSW),丰富度指数(S)等,分析湘南植物群落多样性。结果表明:①维管束植物共有63科131属173种,其中乔木15科21属24种,青冈栎Cyclobalanopsis glauca,细叶青冈C. gracilis,苦槠Castanopsis sclerophylla等为乔木层优势种;灌木层34科60属74种,牡荆Vitex negundo var. cannabifolia,六月雪Serissa japonica与花竹Bambusa albo-lineata较多;草本植物共32科54属63种,多数为禾本科Gramineae植物;层间植物共有13科22属33种,龙须藤Bauhinia championii数量最多;②α多样性分析表明...

The diversity of plant species in 21 plots (5 000 km2) from Southern Hunan area was determined by calculating the indices of species diversity, richness, evenness, and dominance. Analysis included α and β di-versity analyses with the Simpson (S), Shannon-Wiener (SW), Cody (C), and Jaccard (J) Index. For rocky desert treatment and searching the regularities of growth and distribution of plant in rocky desert, applied with random quadrat sampling method and analysis by synthesis method. Results show there are overall presence of 63 families, 13...
