海南岛甘什岭热带低地雨林植物组成与地理成分
Plant Composition and Geographical Elements of the Tropical Lowland Rain Forest of Ganshenling, Hainan Island
摘要
Abstract
In order to reveal the characteristics, property and regular pattern of plant communities, and to provide a theoretical basis for the biodiversity conservation, biodiversity restoration and the ecological service functions assessment in the tropical lowland rain forest of Ganshenling, Hainan Island. We found a piece of typical tropical lowland rainforest in Ganshenling, Hainan nature reserve, established a 1 hm2 permanent sample plot in it. The site factors and situation of vegetation were investigated, the composition and geographical elements of the spermatophytic flora were also analysed. The results were as follows: The vascular plant species belonged to 65 families, 150 genera and 213 species which included 63 families, 148 genera and 211 species of spermatophyte, accounted for 32.66%、 19.29%, 13.56%、 4.69%, 7.65%、 0.78%-0.81% of the number of family, genera and species in Hainan Island and the whole of China, respectively. There are 36 single-species families and 24 depauperate families in experimental zone, they accounted for 92.31% of whole families. Dominant families can be distinguished intuitively. The number of species in each genera varied from 1-6, among which monotypic genera accounted for 76.00%. Pantropic is the maximum type in both areal-types of families and genera predominantly, tropical components were the dominant, which is totally different from the montane rain forest in Jianfenfling. The areal-types of families and genera in Jianfengling have two primary ingredients, those are pantropic type and sub-tropic type. Based on species-area curve in the plot we calculated that minimum sampling area in Ganshenling tropical lowland rainforest was 3600-6400 m2, which surpassed the 4000 m2 in Bawangling tropical montane rainforest. Compared to montane rain forest, the species richness is higher and the types of geographical elements are more plentiful in lowland rainforest.关键词
