摘要:
2013-2015年,对景宁县望东垟高山湿地自然保护区和大仰湖湿地群自然保护区进行了植物资源调查,结合历史资料统计分析了两个保护区种子植物区系。结果表明,两个保护区共有种子植物153科725属1 692种,其中野生种子植物141科644属1 529种。从科级水平看,以寡种科最多,共70科,占总科数的49.6%,其次是单种科29科,占20.6%,大种科最少,仅6个,占总科数的4.3%。从属级水平看,寡种属、单种属极为丰富,分别有243属和353属,占总属数的37.70%和54.8%。科的分布区类型,热带性地理成分63科(不含广布),占总科数的67.0%,温带成分31科,占总科数的33%,说明科的地理成分具有较强的热带性质。属的分布区类型,热带分布类型256属,占总属数(不包括世界分布属)的43.6%,温带分布类型319属,占总属数的54.3%,说明具有温带和亚热带性质。调查显示两个保护区植物多样性丰富,区系起源古老,孑遗植物多,特有属种多,区系成分复杂多样,具有较明显的过渡现象。
Abstract:
Investigations were conducted on plant resources from 2013 to 2015 in Jingning Wangdongyang Nature Reserve for Alpine Wetland of Zhejiang and Jingning Dayanghu Nature Reserve for Wetlands of Zhejiang. The result showed that there were 1692 species seed plants belonging to 725 genera of 153 families, among them, 1529 species belonging to 644 genera of 141 families were wild plant. Oligotypic families(2-9 species) had 70, occupying 49.6% of the total ones, followed by monotypic one(1 species) which had 29 families, accounting for 20.6% of the total ones. Polytypic one had (≥50 species) only 6 families, accounting for 4.3%. Oligotypic and monotypic genus had respectively 243 and 353, which accounted for 37.70% and 54.8% of the total genera. The areal types of families (without cosmopolitan)of seed plant in the investigated reserves, there were 63 families of tropical geographical elements and 31 families of temperate ones, occupying 67.0% and 33% respectively of the total ones, indicating that it had strong properties of tropic. The areal types of genera (without cosmopolitan), there were 256 tropical geographical elements and 319 temperate ones, taking up 43.6% and 54.3% respectively of the total ones, illustrating that it had properties of temperate and subtropic.
