西藏墨脱藓类植物多样性及垂直分布规律研究
A Study of the Diversity and Vertical Distribution of Mosses in Motuo,Xizang
摘要
Abstract
To investigate the vertical distribution of mosses in representative areas of Motuo,providing baseline data for further studies on the distribution and ecological adaptation of bryophytes throughout the Motuo region,a combination of line survey and general mining was used to conduct field specimen collection,species identification and ecological statistical analysis in the area.(1)A total of 698 species(including varieties and subspecies)of mosses belonging to 217 genera and 58 families were collected in the area.(2)The richness of mosses in the TRF vegetation distribution zone among the five vertical distribution zones in the area was the highest,with a total of 298 species,accounting for 42.69%of the total number of mosses in the area;the richness of mosses in the ASM distribution zone was the lowest,with only 14 species,accounting for 2.01%of the total number of mosses in the area.(3)The diversity of mosses in the area showed a bimodal trend of first decreasing,then increasing,and then decreasing with increasing altitude.The vegetation distribution zone with an altitude range of 500～1 000 m had the richest diversity and had the highest similarity with the SEB vegetation distribution zone with an altitude range of 1 000～1 800 m,while the diversity of mosses in the vegetation distribution zone with an altitude range of 3 800～4 400 m was the rarest,and the similarity with the other distribution zones was very low.This showed that with the increase in altitude,the corresponding changes in vegetation types and climatic conditions had a significant impact on the distribution and diversity of mosses.The mosses in Motuo showed obvious vertical distribution pattern with increasing altitude.关键词
