不同植被类型显著影响其生物多样性的变化,金佛山石灰岩地区植被在受到中轻度人为干扰初期,其物种丰富度和多样性、均匀度指数均有提高;砂页岩地区植被受到中轻度干扰,丰富度和多样性指数有所提高,均匀度指数呈相反趋势;石灰岩地区原生植被生物多样性和物种丰富度指数较砂页岩地区的原生植被低。 - A preliminary study on the species composition , ecological characteristics and present distribution of vegetations in mengyang area , the largest part of xishuangbanna nature reserve , shows that there are 7 vegetation types , 15 formations , 24 community types in this area . the vegetation map was made by using gis software ( arc / info ) , and the area and distribution pattern of each community was obtained . the subtropical monsoon evergreen broad leaved forest occupies the largest part , with an area of 41 . 26 % of the whole , and the tropical rain forest occupies less than 10 % of the whole area . according to the topography , altitude , climate characters and present distribution of the vegetation , and based on the landscape type map , an original vegetation map under natural conditions was obtained , which could provid a theory for the vegetation restoration , especially for the tropical rain forest and its habitat , and for the development of the nature reserve
对西双版纳勐养自然保护区植被的类型进行了划分,包括人工和自然群落,共有7个大类、 15个群系、 24个群落类型分布.对每个类型的主要组成种类、生态特征和分布现状进行了初步研究.利用地理信息系统软件制取植被图并获得了各种植被类型的分布面积和分布格局特征,这一地区亚热带季风常绿阔叶林的分布面积和所占比例最大,达总面积的41 . 26 % ;而热带雨林面积不超过总面积的10 % .依据地形、海拔、气候和现状植被分布的规律,在获得景观类型图的基础上,得到了可以反映这一地区在完全自然条件下植被可能分布的状况的还原植被图,为保护区的发展和植被的恢复提供了理论依据。 - In original and jamming slightly vegetation , because dead roots , branch and leaves back to soil , soil organic matter higher , soil available phosphorus higher , too ; chemical and physical characters of soil were stabilization . the reason were original vegetation have more species and structure of community was stable . the degradation of fertility and structure of soil in secondary vegetation was influenced by change with structure and form of community
在人为干扰小的原生性森林,植物种类丰富,群落结构稳定,植物死根系和枯枝落叶全部回归土壤,土壤有机质含量高,养分呈有机态为多,故有效磷较高,土壤理化性质较稳定;次生植被群落土壤结构和肥力的退化是由于群落组成和结构的改变导致枯枝落叶成分和土壤发规白山地还小问沙消民俗一非定俗地征王卿乔忡旺w比收财育环境差异而引起,次生植被土壤的退化状态随植被退化程度不同而有差异。
