浙江天台黄润岩生植被群落结构多样性初步分析
Analysis of structure diversity of species community in rock vegetation of Tiantai Huangrun of Zhejiang
摘要
Abstract
[Objective]Wild rock vegetation resources in Tiantai Huangrun, Zhejiang were investigated to enrich wild rock vegetation resources in this region and to provide references for selection and introduction of rock plants. [Method] Statistics acquired from belt transect method was used to analyze the fundamental structure component of rock vegetation community. The important values and Shannon-Wiener index were calculated for each sample in herbaceous layer and shrub layer to investigate the structure of community and its diversity. [Result]The results showed that Huangrun was abundant in rock plants having 38 families, 44 genera and 57 species, of which ferns had 6 families, 7 genera and 8 species. Species diversity index of herbaceous layer was greater than shrub layer, and Shannon-Wiener index was different too. Slope and direction affected the distribution of plants. Curve of glade proportion was almost the same between herbaceous layer and shrub layer. Species diversity index in herbaceous layer was in accordance with the curve tendency of glade proportion, while shrub layer was the opposite. Dominant species were Lmperata cylindrica, Sedum sarmentosum and Millettia reticulata. [Conclusion]Rock vegetation community had ample species with stable structure in Tiantai Huangrun. Saxifraga stolonifera and Sedum sarmentosum could be planted in rock gardens, while Lmperata cylindrica and Millettia reticulata could be used selectively as they required a little more soil.关键词
