福建省维管束植物物种多样性及其分布格局

Vascular Plant in Fujian Province:Species Diversity and Distribution Pattern

截至2011年7月,福建省发现的维管束植物有250科1 611属4 839种(含亚、变种),是中国植物多样性较为丰富的省份之一.福建维管束植物主要集中分布在武夷山脉和戴云山脉地区,其中武夷山脉北段具有物种丰富度高、特有种多等特点,是中国11个具有全球意义的生物多样性保护的关键区之一.武夷山脉中段是福建省自然保护区分布最为密集的区域,也是福建省植物物种多样性最为丰富的地区.以福建戴云山国家级自然保护区为核心的戴云山脉中段,分布着大面积的南亚热带季风常绿阔叶林,有着丰富的植物多样性,位于戴云山脉南段的博平岭则是福建省南亚热带雨林森林生态系统的典型分布区,其植物种类在福建省植物物种多样性中独树一帜.分布在福建滨海湿地的维管束植物虽然种类不多,但地域特色显著,是福建维管束植物的重要组成部分.

Fujian province is rich in vascular plant, which in terms of plant diversity in China, it comprises 250 families, 1 611 genera, 4 839 species （including subspee：ies and variant species）. In the province, the vascular plants are mainly distributed in Wuyi and Daiyun Mountains, especially the north part of Wnyi Mountain which is famous for its vascular plant＇s high species richness and rich en- demic species. In fact the area is one of 11 globally significant biodiversity conservation critical areas in China. The middle part of the Wuyi Mountain is an area where not only nature reserves intensively distribute, but is also the richest area in plant diversity. The middle part of the Daiyun Mountain, whose core area is Daiyun Mountain National Nature Reserve, contains large areas of south subtropical monsoon evergreen broad-leave forest, with a big wealth of plant diversity. The Boping Ridges, which are located at south of the Daiyun Mountain, is a typical area of south subtropical rain forest ecological system in the province, with unique plant species and plant diversity. In coastal wetlands of the province, there are few species of vascular plants, but with its outstanding regional characteristics, the vascular plants there are still important for the province.
