Based on investigation and statistical analyses, the flora of woody plants of Shanxi reservoir section in Zhejiang Province is studied in the paper. There are 684 species and varieties, 293 genera and 91 families of woody plants in this area. In the flora, the pantropic type of genera has 19.3%, the East Asia type is 17.9%, the north temperate type is 14.0%, the Tropic Asia type is 12.6%. On the analyses, the flora of Shanxi ought to belong to the South China flora.

温州珊溪库区的木本植物共有 684种 (包括种下等级 ) ,隶属于 2 91属 93科。本文对该区的木本植物区系作了分析研究 ,表明本区系以热带成分为主 ,温带成分也占有相当的比重 ,与亚热带的特性基本符合 ,同时也说明本区系属于华南、华东两个植物区系的交汇点 ,但华南植物区系特性更为明显 ,应是华南植物区系的北缘。

Hunan Province and Hubei Province are located at N24°39′~33°20′and E108°21′~116°07′, belonging to subtropical monsoon zone, where climate is warm and wet,and terrain is complex. Vines are very rich in the area, but its research is virtually a blank. In this paper we studied on the flora of the seed vines in Central China region, choosing Hunan Province and Hubei Province as the representative. Based on statistics of plants list of the area, there are 838 species of seed vines belonging to 175 genera in 62 families,...

Hunan Province and Hubei Province are located at N24°39′~33°20′and E108°21′~116°07′, belonging to subtropical monsoon zone, where climate is warm and wet,and terrain is complex. Vines are very rich in the area, but its research is virtually a blank. In this paper we studied on the flora of the seed vines in Central China region, choosing Hunan Province and Hubei Province as the representative. Based on statistics of plants list of the area, there are 838 species of seed vines belonging to 175 genera in 62 families, of which 784 species of 159 genera in 60 families are native. We analyzed the speciality of seed vines flora at the families, genera and species levels in depth and discussed the relationship of the seed vines in Central China region with its neighbouring regions and the differentiating zones within the area. Our results showed that the seed vines accounts for 11% of the total seed plants in Central China region and 61.7% of the total seed vines were concentrated on the large families with 30 species or more. Its Tropical members are obviously more than in the Temperate. The members of the Pantropic, the Tropic Asian, the E.Asian (especially Chinese) endemics and the E.Asian-N.America disjuncted patterns at the family and genera levels were relatively rich, and many of them were archaic elements. Moreover, there were rich endemic elements in the area with one E.Asian endemic family, 6 Chinese endemic genera and 507 Chinese endemic species including 35 endemic species to the Central China region. The flora of the seed vines of Central China region was characterized with rich species, diversity areal-types, rich endemic and archaic elements. Compared with the seed flora of the Central China region, the seed vines flora was of relatively strong tropical characteristics and shared more geographic resources with Himalayan region and the southwest of China.

以湖南和湖北两省为代表对华中地区藤本种子植物的区系进行了研究。本区共有藤本种子植物62科175属838种,其中土著种类有60科159属784种。在科、属、种的水平上对藤本种子植物区系特性进行了较深入的统计和分析,并对本区藤本种子植物与邻近地区的关系、本区内的藤本种子植物的地带性分异进行了探讨。统计表明,本区藤本种子植物种数占该区种子植物总种数的11%,且61.7%的种类主要集中在30种以上的大科中;热带分布型明显多于温带分布型;泛热带、热带亚洲、东亚(中国)特有和东亚—北美间断分布科属比较集中,其中许多属为古老成分;本区藤本种子植物特有成分丰富,计有东亚特有科1科、中国特有属6属、中国特有种507种(其中华中地区特有种35种)。通过研究认为:本区藤本种子植物具有种类丰富、分布类型多样、特有成分较多、区系较古老的特点;与本区的全部种子植物区系相比,藤本种子植物区系的热带性更强,具有明显的热带亲缘性,并与喜马拉雅及中国西南有较强的地理渊源。

The flora and community characteristics of semi-humid evergreen broad-leaved forest in Lancangjiang Nature Reserve at the altitude of 2 300~2 540m was investigated and studied.The results showed that the plant community of Lancangjiang Nature Reserve had five obvious layers,there were 44 families,93 genera,149 species of seed plants and 7 families,9 genera,13 species of fern plants recorded from 5 plots totaled 2 500 m~(2).As for generic distribution,the Pantropic areal type was the majority,with 24 genera,followed the tropical Asia distribution with 15 genera.There were 51 tropical genera,which was higher than that of temperate genera(32 genera).There was no genus of Chinese endemic.On the genus level,the semi-humid evergreen broad-leaved forest in Lancangjiang Nature Reserve had significant tropical characteristics.There were 76 species endemic to China,among which,2 species were endemic to Lancangjiang Nature Reserve,28 species were endemic to Yunnan,46 species were endemic to other regions of China with 27 endemic species of southwest China.The result indicated that the origins of the components of semi-humid evergreen broad-leaved forest in Lancangjiang Nature Reserve were mainly Yunnan and southwest areas of China.There were also Sino-Himalayan flora and tropical Asia flora,with the number of 32 species and 30 species respectively,which showed the origin of Himalayan region and tropical Asia.In this community,there were 113 temperate species,which was higher than that of tropical species(35),which indicated that under the upland condition of this nature reserve,a lot of temperate species formed and entered.The relatively dry climate of this region might be the reason that the semi-humid evergreen broad-leaved forest could distributed in the areas with the altitude up to 2 540 m,which was higher than both Mt.Gaoligongshan and Mt.Wuliangshan.It perhaps related to the rainfall that the region's seed plant were fewer than Mt.Wuliangshan.Constituted of same dominant species,such as Lithocarpus xylocarpus, and L.hancei,formed mid-montane humid evergreen broad-leaved forest in Mt.Gaoligongshan and Mt.Wuliangshan whereas semi-humid evergreen broad-leaved forest in Lancangjiang Nature Reserve.These results indicated that the communities with same dominant elements could be separated into different high grade vegetation types such as vegetation subtypes and this was mainly decided by the ecological characteristics of the community instead of totally decided by the flora.

对澜沧江自然保护区分布于海拔高度2 300~2 540 m较原始的半湿性常绿阔叶林的群落学及植物区系特性进行了调查研究。其2 500 m2的样地调查统计资料表明,组成本区半湿性常绿阔叶林的种子植物有44科、93属、149种,蕨类植物有7科、9属、13种。其群落的5个层次组成显明。群落中,泛热带分布的属最多,有24属;其次为热带亚洲及其变型的属,有15属。热带性质的属(51属)多于温带性质的属(32属),无中国特有属,显示该保护区的半湿性常绿阔叶林在属的水平上具有较强的热带性质。群落中,中国特有种多达76种,包括保护区特有的2个种,与云南共有的28种,与中国其他地区共有的46种,其中与西南片共有27种,表明本保护区半湿性常绿阔叶林的构成种类主要起源于云南和我国西南地区。其群落中也有一定数量的中国—喜马拉雅成分(32种)和热带亚洲成分(30种),显示与喜马拉雅地区和热带亚洲地区的区系渊源。群落中温带性质的种(113种)比热带性质的种(35种)多,说明在本区山地条件下,在该群落中形成和迁入了大量温带的种类。以此认为,相对干燥的山地气候,是本区的半湿性常绿阔叶林能够分布到海拔高度2 540 m,明显高于高...
