摘要
通过资料收集、外业调查和内业统计分析,对野三河自然保护区种子植物物种多样性进行了研究。结果表明:保护区共有野生种子植物1106种(含种下分类群),隶属于150科533属;野生种子植物150个科可划分为11个分布区类型和10个变型,以热带成分占优势,占非世界分布科的56.88%;533个属可划分为14个分布区类型和17个变型,以温带成分占优势,占非世界分布属的59.06%;与相邻5个自然保护区相比,野三河与木林子自然保护区的相似性系数最高。本研究旨在为野三河自然保护区生物多样性保护、野生植物资源的开发、自然保护区规划建设和管理提供本底资料和科学依据。
The diversity of plant species of the Yesanhe Nature Reserve was studied by field investigation and indoor analysis. The results showed there were 1106 species （including infraspecific taxon） of wild spermatophyte belonging to 533 genera and 150 families. The 150 families of wild spermatophyte were divided into 11 areal-types and 10 variety-types. Tropical elements were the dominant components, in which tropical families contributed 56.88% in total （excluding cosmopolitan families）. The 533 genera of wild spermatophyte were divided into 14 area-types and 17 variety-types. Temperate elements were dominant components, in which temperate genera contributed 59.06% in total （excluding cosmopolitan genera）. Com- pared with the flora of five neighboring areas, the flora of the Yesanhe Nature Reserve showed high similarity with Mulinzi Nature Reserve. The purpose of this study was to protect biological diversity and provide background information for the construction of Yesanhe Nature Reserve.
