Based on the data of 22 plots of communities, the mixed evergreen and deciduous broadleaf forests on limestone hills have been studied by numerical classification methods. According to the diagram of floristic similarity, 22 plots can be mainly divided into 6 community types; and by cluster analysis all the plots can be divided into 6 formation groups, 7 formations and 9 subformations. The results conform basically with the real conditions.

At sharptooth oak (Quercus alimuz var' acuteserrata) community of lower and middle mountain zones at Huoditang forest region on south-facing slope of the Qinling Mountains the floral elements of north temperate zone were dominant, also there were some species of sub tropi-cal zone and west China. The transition of the floral elements was obvious. 4 association groups were classified by means of cluster analysis (Bray-Curtis distance) and two-dimensional polar ordination, which are: Smilax sta;is-Populus dauidiana-Q....

At sharptooth oak (Quercus alimuz var' acuteserrata) community of lower and middle mountain zones at Huoditang forest region on south-facing slope of the Qinling Mountains the floral elements of north temperate zone were dominant, also there were some species of sub tropi-cal zone and west China. The transition of the floral elements was obvious. 4 association groups were classified by means of cluster analysis (Bray-Curtis distance) and two-dimensional polar ordination, which are: Smilax sta;is-Populus dauidiana-Q. aliena var. acutesterrata, Spiraea fritschiana-Rhus chinensis+P. dauidiana-Q. aliena var. acuteserrata, Sinarundinaria nitida -Pinus armandi+ Pinus tabulae formis-Q. aliena var. acuteserrata and Corylus heterophylla -Castanea mollissima- Q. aliena var. acutesrrata- At adolscent stage community dominance, a diversity and species abundance of the sharptooth oak forest reached the maximum.

秦岭南坡火地塘林区低中山地带锐齿栎群落的植物种类组成以北温带区系成分为优势,亚热带和华西等区系占一定比重,植物种类组成的过渡性比较明显。经Bray-Curtis距离等级聚类分析和极点排序,划分出4个群丛组,即鞘柄菝奖—山杨—锐齿栎群丛组,华北绣线菊—漆树+山杨—锐齿栎群丛组,箭竹—华山松+油松—锐齿栎群丛组,榛子—板栗—锐齿栎群丛组。近熟林时期,锐齿际林的群落优势度、α多样性和种类丰富度达最大值。

A total of 248 mollusc species were found in the intertidal zone of islands of Fujian, which belong to 5 classes, 78 families, 161 generas. Using similarity index of community, hierarchical clustering and polar ordination, we studied the distribution of mollusca community in intertidal zone of islands of Fujian. The result indicated that the mollusca community was divided into the: estuary, harbour and the open sea types. The distribution of mollusca community is related to the island location and its environment. The salinity and motive power of the water were major factors which influence the community.
