摘要
为了解青海省野生种子植物的分布及种类多样性,试验采用野外采集植物和文献分析方法分析了青海省植物区系的基本特点。结果表明:青海省野生种子植物共计94科557属2 497种。世界广布的科占据绝对优势,其次为泛热带分布和北温带-南温带间断分布类型。属的分布上,北温带分布为优势分布类型,世界分布和旧世界温带分布为次优势分布类型。种的方面,祁连山、湟水河流域、青南高山地区植物物种丰富,而柴达木地区和青海湖区域植物物种相对贫乏,这5个典型区域种的区系特点存在明显的差异。青海没有特有科,特有的属和种较为丰富,特有属有26属,特有种有90种。
To understand the distribution and species diversity of wild seed plants in Qinghai province, the methods of collecting plant from the field and literature analysis were used to analyze the basic characteristics of the plant floras in Qinghai province. The results showed that a total of 2497 species from 557 genera in 94 families of wild seed plants exist in Qingbai Province. Among them, the cosmopolitan families occupy an absolute advantage were the dominant distribution types, followed by pantropical distribution and the disjunct distribution types from the North temperate zone to the South Temperate. In terms of genera level distribution, the distribution of the North Temperate belongs to the dominant distribution type, and the cosmopolitan distribution and the distribution of the Old World temperate belong to subdominant distribution types. In terms of species level distribution, Qilian Mountains, Huangshui River Basin and the alpine area in the south of Qinghai province are rich in plant species, while the Qaidam region and the Qinghai Lake area are relatively poor in plant species. There are obvious differences in the characteristics of flora between the five typical areas. Qinghai province has no endemic families, but it has rich endemic genera and species, and there are about 26 endemic genera and 90 endemic species in Qinghai province.
