The Investigation And Evalution Of The Plant Community Of Hangzhou Ling Yin And Hu Pao Meng Quan Mountain Scenic Area

In this paper,the eighty plant community samples of ling yin and hu pao meng quan two mountain scenic area have been investigated,and the aspects of plant community style,plant section department character,community structure,species diversity have been studied. I also select thirty respresentive plant community samples,and make comprehensive evaluation for those samples in use of AHP arrangment analytical method, figure out its comprehensive sight grade point in the end.The evergreen broad-leaved forest possess the most proportion in all investigated sample area,the evergreen coniferous forest possess the least proportion.The number of each kind of the plant community style sample area is ordered from more to less is as follow: the evergreen broad-leaved forest,the evergreen deciduous board-leaved mixed forest,the deciduous board-leaved forest,the coniferous board-leaved mixed forest,the deciduous coniferous forest and bamboo forest,the evergreen coniferous forest.There are 79 families 162 generas 225 species vascular plant in the Ling yin and Hu pao meng quan mountain scenic area .It contians 8 families 9 generas 12 species fern and 71 families 153 generas 213 species seed plants. In this paper, the 71 families seed plants have been studied according to the specialist wu zheng yi's《The Areal-types of the World Families of Seed Plants》.And get resuilts as follow: world wide spread plants have 21 families;Pantropic plants have 17 families;East Asia and Tropic America disjuncted plant have 6 families;Old World Tropics plants have 4 families;Tropic Asia to Tropic Australasia Oceania plants have 4 families;Tropic Asia plants have 6 families;Northern temperate zone plants have 6 families.East Asia&Northern America disjuncted plants have 2 families.Old World temperate zone plants have 2 families;Mediterranean,West Asia to Center Asia plants have 1family;East Asia plants have 3 families;Endemic to China plants have 1 family.The average species number of ling yin scenic area S: herbage layer>shrub layer>arbor layer; The average Gleason species abundant degree index: herbage layer>shrub layer>arbor layer;The average Margalef species abundant degree index: shrub layer>herbage layer>arbor layer;The average Shannon-Wiener index H': herbage layer>shrub layer>arbor layer;The average Pielou index : shrub layer >arbor layer> herbage layer.The average species number of ling yin scenic area S: herbage layer>shrub layer>arbor layer; The average Gleason species abundant degree index: herbage layer>shrub layer>arbor layer; The average Margalef species abundant degree index: shrub layer>herbage layer>arbor layer; The average ecological advantage degree Simpson index: herbage layer>arbor layer>shrub layer; The average Shannon-Wiener index H': herbage layer>shrub layer>arbor layer; The average Pielou index : herbage layer>arbor layer>shrub layer. The average Pielou index : shrub layer>arbor layer>shrub layer.In the comprehensive evaluation of 30 selected plant community ,There is only one plant community sample of comprehensive evalution indexⅠ,possesses 3.33 percent of all plant community samples, There is 17 plant community samples of comprehensive evalution indexⅡ, possesses 56.67 percent of all plant community samples, There is 12 plant community samples of comprehensive evalution indexⅢ,possesses 40 percent of all plant community samples.
