摘要:
在对岩下大鲵自然保护区进行种子植物调查和标本采集的基础上,进行该地区种子植物区系基本组成科、属、种的分析,并与贵州东部、南部、西部、北部和中部5个邻近自然保护区的植物区系及其相似性系数进行了比较。结果表明:(1)该区内有种子植物131科、380属、630种,优势科较为明显,但优势属不明显。(2)区系分析表明,该地区区系性质以温带成分占优势,其中温带分布属有197属,占总属数的57.94%。热带分布类型亦占相当优势,有141属,占总属数41.47%,说明该地区种子植物区系具有热带到温带过渡的性质。(3)地理成分复杂,特有成分贫乏。(4)该保护区与其邻近地区植物区系相似性很大,其中与关山、宽阔水植物区系的相似性最大,太平山、茂兰、草海次之。
Abstract:
Based on the investigations of the vegetation and the collection of samples, the flora composition of Yanxia Nature Reserve for Megalobatrachus davidianua in terms of families, genera, and species were analyzed. The floristic characteristics and similarity coefficient were compared with five neigh biring Nature Reserves in Guizhou. The results were as follows: (1)There are 630 species in 380 genera and 131 families of seed plants in the region. The dominant families are prominent, but the dominant genera are not prominent. (2) Based on the analysis of the flora of families and genera construction in the area, it is indicated that the flora has typical characteristics of temperate distributions, especially in the level of genus. There are 197 genera in the area which account for 57.94% of overall gerera. The tropical distribution compositions of genera play an important role in the construction of the flora. There are 141 genera in the area which account for 41.47%. It has evident transitional character. (3) Its geographical components are complex and endemic compositions are poor. (4) The floristic characteristics of Yanxia Nature Reserve is closely allied to its adjacent regions.
