1) The Compositae in Tibet so far known comprise 508 species and 88 genera,
which nearly amounts to one fourth of the total number of genera and one third of the
total number of species of Compositae in all China, if the number of 2290 species and 220
genera have respectively been counted in all China. In Tibet there are all tribes of Com-
positae known in China, and surprisingly, the large tribes in Tibetan Compositae are
also large ones in all China and the small tribes in Tibet are also small ones in all China.
Generally speaking, the large genera in Tibet are also large ones in all China and the
small genera in Tibet are likewise small ones in all China. In this sense it is reasonable to
say that the Compositae flora of Tibet is an epitome of the Compositae flora of all China.
In the Compositae flora of Tibet, there are only 5 large genera each containing 30
species or more. They are Aster, Artemisia, Senecio, Saussurea and Cremanthodium. And
5 genera each containing 10—29 species. They are Erigeron, Anaphalis, Leontopodium,
Ajania, Ligularia and Taraxacum. In addition, there are 77 small genera, namely 87%
of the total of Compositae genera in Tibet, each comprising 1—9 species, such as Aja-niopsis, Cavea and Vernonia, etc.
2) The constituents of Compositae flora in Tibet is very closely related to those of
Sichuan-Yunnan provinces with 59 genera and 250 species in common. Such a situation
is evidently brought about by the geographycal proximity in which the Hengtuang Shan
Range links southeastern and eastern Tibet with northern and northwestern Sichuan-
Ynnnan. With India the Tibetan Compositae have 59 genera and 132 species in common,
also showing close floristic relationships between the two regions. Apparently the floris-
tic exchange of Compositae between Tibet and India is realized by way of the mountain
range of the Himalayas. The mountain range of the Himalayas, including the parallel
ranges, plays a important role as a bridge hereby some members of the Compositae of
western or northern Central Asia and of the northern Africa or of western Asia have
migrated eastwards or southeastwards as far as the southern part of Fibet and northern
part of India, or hereby some Compositae plants of eastern and southeastern Asia or
Asia Media have migrated northwestwards as the northern part of Central Asia.
Some of the species and genera in common to both Tibet and Sinjiang indicate that
this weak floristical relationship between these regions is principally realized through two
migration routes: one migration route is by way of the Himalayas including the parallel
ranges to Pamir Plataeu and Tien Shan, or vice versa. The other migration route is by
way of northern Sinjiang to Mongolia, eastern Inner Mongolia, southwards to Gansu,
Qinghai (or western Sichuan), eastern Tibet up to the Himalayas, or vice versa.
However, Tibet is not entirely situated at a migration crossroad of the floral ele-
ments. An ample amount of the data shows that Compositae flora have a particular
capability of development in Tibet. of the total number of species of Tibetan Com-
positae, 102 species and 1 genus (Ajaniopsis Shih) are endemic. Besides, 8 genera are re-
gional endemics with their range extending to its neighbourhood. The higher percentage
of endemics at specific level than at generic in Tibetan Compositae may be a result of
active speciation in response to the new enviromental conditions created by the uplifting
of the Himalayas. The flora in Tibetan Plateau as a whole appears to be of a younger
age.
3) The uprising of the Himalayas and of the Tibetan Plateau accompanied by the
ultraviolet ray radiation, the microthermal climate and the high wind pressure has, no
doubt, played a profound influence upon the speciation of the native elements of Tibetan
Compositae. The recent speciation is the main trend in the development of the Com-positae flora native in Tibet in the wake of upheaval of the plateau. 相似文献

在我国藏北渐新世地层中发现了攀鲈和鲃类新属种,其现生近缘类型都生活在亚洲和非洲的热带地区。这不仅在鱼类的系统发育和动物地理上具有重要意义,并且表明青藏高原腹地在距今26 Ma前仍然为温暖湿润的低地,伴生的棕榈、菖蒲等植物化石也指示同样的环境,说明当时由印度洋来的暖湿气流至少可以深入到藏北地区。自那时起,高原内部的地理特征与自然环境经历了巨大的变化。青藏高原在中新世持续隆升,至上新世达到现代高度,形成冰冻圈环境。在札达盆地的上新世沉积中发现了披毛犀、雪豹、北极狐和盘羊的祖先类型,显示适应严寒环境的第四纪冰期动物群起源于青藏高原,由此提出和进一步完善了寒冷适应性动物起源与扩散的"走出西藏"理论。 相似文献

Meto situated in the southeastern Tibet, about 30°N' Lat., enjoys a tropical
climate. Below 2500m. altitude, there are monsoon rain forests and broad-leaved
evergreen forests, from which the Tibetan scientific expedition has gathered 71 speci-
mens of epiphyllous liverworts representing 26 species and 2 varieties in 13 genera.
This may be considered as a distinct subzone for the epiphyllous liverworts in the
south part of the Tibetan East Himalaya. 相似文献

基于MODIS的西藏高原土地覆盖分类研究 总被引：1，自引：0，他引：1
嵌的MODIS遥感图像,用最大似然估计分类器对西藏高原的土地覆盖类型进行了分类,并采用西藏高原数字高程模型(DEM)对MODIS分类结果进行了分析和改进,最后分别用混淆矩阵和图集中西藏高原植被分类汇总面积对MODIS土地覆盖分类结果进行了分类精度评价。结果表明:①MODIS遥感图像能够有效地分类出西藏高原的主要土地覆盖类型;②根据西藏高原植被的垂直带性分布特点,由DEM改进的MODIS土地覆盖分类精度明显提高,主要土地覆盖类型的面积绝对误差都小于2%,其中,河流与湖泊、森林、高寒荒漠、作物和山地草原的绝对误差都在1%以下;③混淆矩阵分析的平均分类精度为87.68%。 相似文献
