摘要
在野外调查的基础上,结合查阅相关资料,对峨眉山种子植物的垂直分布特征进行了统计分析。峨眉山种子植物共2 876种,含物种数大于10的科70个,物种数随海拔升高呈现先增加后减少的单峰变化格局,在海拔1 100~1 900 m范围内达到最大,为1 260种。各植被带内不同生活型植物占该带总物种数比例随海拔高度增加呈不同变化趋势,乔木、藤本植物为单峰分布,在海拔1 100~1 900 m最高,分别为27.9%和6.9%;草本植物先减少后增加,灌木则随海拔增高呈递减趋势。自然植被垂直带是各自然要素综合作用的结果,研究种子植物的垂直分布规律对了解该区域自然环境特点具有重要意义。
By applying methods of field investigation and online resources,the authors performed statistical analysis on elevational gradients in phytogeography in Mt.Emei.The result showed that 2876 seed plants species were recorded,in which 70 families content at least 10 species.Furthermore,the change of species richness showed a hump-shaped distribution,that is,increase first then decrease with the altitude.And at an altitude of 1100-1900 m,reaches the maximum value of 1260.Plant life forms the proportion of the total in each vegetation zone were counted,they are varied from altitude gradients to another.Woody planets and vines were hump-shaped distributed too,and the maximum value appeared at an altitude of 1100-1900m,27.9%and 6.9%respectively;Herbs decreased first and then increased,while shrubs decreased with the elevation.Vertical vegetation belt is characterized by regional climate,hydrology,soil and human activities.The research of spermatophyte's vertical distribution has an important significance for understanding the Regional natural environment.
