徐州潘安湖国家湿地公园植物区系特征分析

Analysis on the Floral Characteristics of Pan'an Lake National Wetland Park in Xuzhou

针对采煤塌陷区湿地公园植物群落构建问题,在对徐州潘安湖国家湿地公园植物进行实地调查的基础上,对其植物群落组成及植物区系特征进行分析.研究结果表明:调查区域共有种子植物97科227属353种(含变种),含10种植物以上的有7科,含82属149种;单种科共42科;科、属、种的配比特征为较少的科、属含较多的种,较多的科、属含较少的种;在科的分布区类型中,世界广布区类型34科,热带分布区类型38科,温带分布区类型22科,分别占总科数的35.05%、39.18%和22.68%,含物种较多的优势科分别属于世界广布区类型和温带分布区类型;在属的分布区类型中,温带分布区类型居首位,有128属,其次为热带分布区类型,有63属.

Based on the field investigation of the plants in Pan'an Lake National Wetland Park in Xuzhou,the plant composition and floristic characteristics were analyzed in order to provide scientific basis for the plant community construction of the wetland park in coal mining subsidence area.The results showed that there were 353 species(including varieties)of plants belonging to 97 families and 227genera.There were 7 families with more than 10 species,including 149 species of 82 genera.The single-species families were 42.The proportion characteristics of families,genera and species was that more families and genera contained fewer species whereas fewer families and genera contained more species.Among the areal types of families,there were 34 cosmopolitan families,38 tropical families and 22 temperate families accounting for 35.05%,39.18%and 22.68%of the number of families.The dominant families with more species belonged to the cosmopolitan and temperate families.Among the areal types of genera,the temperate genera type contained the largest number of genera as 128 and the tropical type contained the second largest number of genera as 63.
