摘要
对松树山自然保护区种子植物的组成特征、区系地理成分进行了分析。结果表明:该区植物种数较丰富,有种子植物85科288属524种,被子植物占优势。科的组成分析表明,优势科现象十分显著。属种的地理成分分析表明,温带成分的属种占优势,热带成分的属种所占比例很小,表明温带属性是该地区植物区系的基本属性。区系地理成分复杂多样、联系广泛。特有现象不明显。
Abstract：According to the analysis on composition characteristics, floristic geographic element of seed plants in Songshushan Nature Reserve （SNR） , the results show that there are 524 native species belonging to 288 genera in 85 families, with angiosperms taking the dominant in flora. The analysis of family composition shows that the domi- nant family phenomenon is notable. Geographical composition analysis of genus and species in SNR showed that temperate composition is dominant, but tropical composition takes a small proportion. The flora in this region shows a significant temperate feature. The floristic relationship is complex and in wide connection. The number of endem- ism in this flora is less.
