高黎贡山百花岭景区生物多样性丰富,利用25个样方调查资料,研究乔木物种多样性变化规律。通过Shannon-Wiener指数、Margalef指数和Pielou指数分析百花岭景区乔木物种多样性、丰富度及均匀度,结果表明:在25个样方共记录乔木150种,乔木物种多样性和丰富度随着海拔的升高呈减小的趋势。坡度、坡向对乔木物种多样性产生局部影响。人为干扰与乔木物种多样性呈负相关关系,干扰严重不利多样性指数增加。
The Baihualing scenic spot in Gaoligong Mountain is rich in biodiversity. The survey data of 25 quadrats are used to study the variation of species diversity of trees. The Shannon-Wiener index, Margalef index and Pielou index were used to analyze the species diversity, richness and evenness of arbors in Baihualing Scenic Area. The results showed that 150 species of arbors were recorded in 25 sample plots, and the arbor species diversity and richness varied with altitude The increase is decreasing. The slope and aspect have a local effect on the species diversity of trees. Anthropogenic disturbance has a negative correlation with arboreal species diversity, with serious disturbance and diversity index increasing.
