摘要:

为了揭示滇西地区核桃林下草本植物丰富程度,以漾濞县为例,调查分析了核桃林地草本植物多样性特征。结果表明:(1)漾濞县核桃林下草本植物共调查到115种,隶属于36科104属,以菊科、唇形科及禾本科为主,物种数量达41种,占总种数的35.7%。(2)单属科是该区域草本植物多样性的重要组成成分,占总科数的41.7%。(3)物种出现频度及重要值较高的种涉及9科16种,以菊科、唇形科及廖科为主。(4)核桃林下草本植物多样性指数与海拔相关性不高,物种丰富度指数(R)与Shannon-Wiener指数(H)、Shannon-Wiener 指数(H)与Simpson 指数(D)、Simpson 指数(D)与Pielou 指数(J)呈现显著正相关关系。

Abstract:

In order to reveal the abundance of herbaceous plants under walnut forests in western Yunnan, the diversity characteristics of herbaceous plants under walnut forests were investigated and analyzed in Yangbi County. (1) 115 species of herbaceous plants under walnut forests in Yangbi were found, which belonged to 36 families and 104 genera. The herbaceous plants are mainly Compositae, Labiatae and Gramineae, with the number of species reaching 41, accounting for 35.7% of the total species. (2) Single genus family is an important component of herbaceous plant diversity in this region, it accounts for 41.7% of the total number of families. (3) The species with high occurrence frequency and important value involve 9 families and 16 species, mainly Compositae, Labiatae and Liao family. (4) The correlation between the diversity index of herbaceous plants under walnut forests and altitude is not high, and there are significantly positive correlations between the species richness index (R) and Shannon-Wiener index (H), Shannon-Wiener index (H) and Simpson index (D), and Simpson index (D) and Pielou index (J).
