安徽与邻近省藓类植物区系数量统计比较

Comparison of Moss Flora of Anhui with Adjacent Provinces,in China

  • 摘要: 区系中的物种丰富度是衡量该区域中植物群落的环境条件、群落结构以及群落发育程度等的重要指标,利用丰富度指数公式,通过对安徽省与其相邻的六个省的藓类植物进行比较,可以看出安徽省藓类植物的物种多样性位居第三,是较为丰富的地区之一;在七省中安徽藓类植物属的系数最低,说明安徽藓类植物区系的丰富度和生境条件的复杂程度是较高的;比较七省的藓类植物丰富度指数与自然地理条件的关系,可认为纬度、降水量、温度以及丘陵山地占该地区总面积的百分比等地理条件综合作用影响藓类植物分布的丰富程度。

     

    Abstract: Anhui province is located in the middlelower reaches of the Yangzi River,distributed in the southeast of China.It covers an area of 139600 km2,and is bordered by the provinces of Jiangsu on the east,Zhejiang on the southeast,Jiangxi on the south,Hubei on the southwest,Henan on the west and Shandong on the north.This thesis is mostly based on about 2000 packages of bryophytes which were mainly collected by the authors in Anhui province during March in 2006 to October in 2007,and based on several past publications available to authors on the bryophytes of the Anhui province.The species abundance index of mosses was measured respectively in seven provinces,and the results showed that is the third most abundant species diversity of mosses which distribute in Anhui province.The generic index of mosses of Anhui is lowest among seven provinces.Compared the species abundance index with physical geographical conditions of seven provinces,it could be considered that geographical location,percent of hill and mountainous areas in the total areas,annual mean temperature,annual precipitation etc.,affect the diversity and richness of mosses.
