摘要:

植物的分布格局和区系分区研究可以为植物资源开发、物种引种、植物多样性保护以及农、林、牧的远景规划提供依据。本文基于最近出版的《浙江植物志(新编)》记载的相关数据, 分析了浙江省野生种子植物的分布格局, 探讨了植物区系的分区。结果显示: 浙江省有种子植物212科1,469属4,430种(不计种下分类群), 其中自然分布的野生种子植物有190科1,085属3,344种, 包含中国特有属45个, 中国特有种1,405个。属级水平上, 广布属有548个, 占野生种子植物总属数的50.5%; 各区域中属数最多的是洞宫山区(851属), 其次是浙东南沿海区(822属)和天目山区(818属), 最少的是浙北平原区(仅有411属)。种级水平上, 种数最多的是洞宫山区(2,304种), 其次是天目山区和仙霞岭区(均超过2,000种), 最少的是浙北平原区(仅有721种)。按照浙江种子植物分布的区域数目分为广布种(904个)、常见种(846个)、局限种(1,000个)、区域独有种(594个); 常见种和局限种共计1,846种, 可归纳为以下6个基本分布式样, 浙北部分布(171种)、浙南部分布(280种)、浙西部分布(109种)、浙东部分布(93种)、浙西至浙东南分布(98种)、浙东北至浙西南分布(37种), 其余为丘陵山地散布和间断分布。根据浙江野生种子植物属和种的分布, 结合前人的区系分区研究成果, 将浙江植物区系划分成2个地区(华东地区和岭南山地地区) 3个亚地区(黄淮平原亚地区、浙南山地亚地区和闽北山地亚地区) 5个小区(浙北平原小区、浙江中北部山地丘陵小区、浙东北沿海小区、浙江中南部山地丘陵小区、浙东南沿海小区)。

Abstract

Aims: Understanding plant distribution pattern and floristic regionalization provides the basis for resource development, species introduction, diversity protection, and long-term planning. Here, the distribution pattern of wild seed plants and the diversity of genera and species in different areas of the Zhejiang Province were analyzed, and the floristic regionalization was discussed.

Method: Based on the distribution data of wild seed plants in Zhejiang, recorded in volumes 2-10 of the recently published Flora of Zhejiang (New Edition), the distribution pattern and floristic regionalization of wild seed plants in Zhejiang was conducted using statistical and analytical methods of species and genera in this study.

Results: Excluding infraspecies, there are 4,430 species of seed plants (representing 1,469 genera in 212 families) in Zhejiang Province, of which 3,344 species are native and wild (representing 1,085 genera in 190 families), including 1,405 species and 45 genera that are endemic to China. At the genus level, there are 548 genera that are widely distributed, which accounts for 50.5% of all wild seed plants in Zhejiang. The most genera are found in the Donggong Mountain area (851), the Southeast Zhejiang coastal area (822) and the Tianmu Mountain area (818) and the least in the North Zhejiang plain (only 411 genera). At the species level, the most are in the Donggong Mountain area (2,304), followed by the Tianmu Mountain and Xianxialing Mountain areas (more than 2,000 species each), and the least are in the North Zhejiang plain area (only 721 species).

Conclusions: According to the distribution of seed plants in Zhejiang, we identify four groups: widely-distributed species (904), common species (846), limited species (1,000), and area-unique species (594). Based on the distribution of 1,846 common and limited species, we recognize six distribution patterns: North Zhejiang (including 171 species), South Zhejiang (280 species), West Zhejiang (109 species), East Zhejiang (93 species), West to Southeast Zhejiang (98 species), and Northeast to Southwest Zhejiang (37 species). The others are s cattered or disjuncted in hills and mountains. According to the genera and species distribution of wild seed plants in Zhejiang and the results of previous studies on regionalization, the flora of Zhejiang is divided into two regions (East China and the Lingnan mountainous region), three subregions (Huang-Huai plain subregion, southern Zhejiang mountainous subregion and the Northern Fujian mountainous subregion), and five districts (North Zhejiang plain district, North to Central Zhejiang mountainous and hilly district, Northeast Zhejiang coastal district, South to Central Zhejiang mountainous and hilly district, and the Southeast Zhejiang coastal district).
