浙江省清凉峰自然保护区苔藓植物区系成分研究

通过对2013~2014年于清凉峰自然保护区采集的1 500余份苔藓植物标本进行鉴定和文献研究,统计分析了清凉峰自然保护区苔藓植物种类组成,区系地理成分及特点,并对该地区与相邻8个地区藓类植物的丰富度系数比较和相似性系数比较,以明确该地区苔藓植物不同的生态分布类型,揭示浙江清凉峰保护区苔藓植物多样性的变化规律。结果表明:(1)浙江省清凉峰国家自然保护区苔藓植物共有62科143属337种(包括3个变种),其中苔类植物20科29属49种,藓类植物42科114属288种。(2)藓类植物的优势科9个、优势属16个。(3)该地区苔藓植物区系成分主要以东亚成分为主(占总种数41.84%),温带成分次之(占总种数28.57%),热带成分再次之(占总种数20.74%)。(4)浙江清凉峰自然保护区苔藓植物区系与浙江省境内的金华山、大盘山、天目山和凤阳山的亲缘关系较为密切。(5)浙江清凉峰自然保护区苔藓植物生态分布类型复杂多样,以石生类型(占总标本数的47.09%)最多,其次为岩面土生(占总标本数的27.68%)和土生(占总标本数的12.85%)类型。

Studies on Flora of Bryophytes in Qingliangfeng National Reserve,Zhejiang Province

Based on identification of collections of 1 500 bryophyte samples and literature survey,we analyzed bryological composition and floristic characteristics in Qingliangfeng National Nature Reserve,Zhejiang Province.The species richness comparison and similarity coefficients of the area with the other eight regions of mosses were discussed.The ecological habitats of the bryophytes were also introduced.The results showed:(1)62 families,143 genera and 337 species(including three variants) from Qingliangfeng National Reserve are reported.Among them,49 species and 29 genera belonging to 20 families are liverworts,288 species and 114 genera belonging to 42 families are mosses.(2)There are nine dominant families and 16 dominant genera all belonging to mosses in the area deleted.(3)The floristic types of bryophytes in the reserve showed that East Asia element is dominant,up to 41.84% of the total species and followed by temperate element with 28.57% of the total species.Tropical is the third with 20.74% of all.(4)The bryoflora of Qingliangfeng National Reserve is more closely related to Tianmu Mountain;Dapan Mountain;Jinhua Mountain and Fengyang Mountain which are in Zhejiang Province.(5)The ecological distribution types of bryophytes are complicated and the most common type is on rock(47.09% of the total number of samples),soil on rock(27.68% of the total number of samples) and soil type(12.85% of the total number of samples) is the second.Therefore,establishing nature reserve plays an important role in researching and for conservation of bryophytes in Zhejiang Province.
