The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

壳斗科在我国有7 属350 多种和变种,是温带、亚热带最重要的森林树种,笔者用离差平方和法对壳斗科植物在中国的地理分布规律进行了研究,认为其落叶类型和常绿类型在空间分布格局上有很大差别。

According to the neighbor-joining tree on 75 leaf cuticle, architecture, flower and fruit characters, the traditional taxonomic system based only on reproductive characters shows some degree of irrationality. 4.

根据叶结构、叶表皮、果实和壳斗等在内的75个特征所建立的邻接树的分支情况大体上和壳斗科根据花、壳斗特征建立的分类系统基本一致,但是有存在不一致的情况,仅仅根据花、壳斗特征建立的分类系统具有一定的不合理性。

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

栲属在地质历史上有着比现在广泛的分布,最早、最可靠的栲属化石记录发现于始新世地层,栗亚科化石在古新世就有发现,化石记录表明栲属起源的时间不晚于古新世,所有的壳斗科及栲属的化石都发现于北半球,现代分布也主要在北半球,壳斗科及栲属起源于北半球可以确认,由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足,具体的起源地尚不能肯定。
