在资料分析和2013年夏秋二季进行的实地调查基础上研究了青岛市城市绿地种子植物区系的科属种构成、种的生活型构成、属的地理分布区类型构成,并比较了青岛市城市绿地种子植物区系与青岛崂山种子植物区系、中国种子植物区系属的地理分布区类型构成差异。结果表明,青岛市城市绿地种子植物区系有种子植物69科155属228种,有含5种及以上的12个较大科、124个单种属、183种木本植物和45种草本植物,有热带分布属32属、温带分布属95属、世界分布属14属和中国特有属14属。青岛市城市绿地种子植物区系有植物种类丰富多样,木本植物种类多,区系中属、种的分化程度高,属的地理分布区类型多样且具有很典型的温带特征和鲜明的中国特色等特点。
Based on field investigations in the summer and the autumn of 2013 and some correlated reference data, the authors analyzed the composition of species, genera and families, life form of species, areal-type of genera of seed plant flora of urban green space in Qingdao City, and compared the difference of areal-type genera composition of the seed plant flora of urban green space in Qingdao City, the seed plant flora of Laoshan Mountain in Qingdao City and the seed plant flora of China. The result of the research showed that there were 228 species seed plants which belonged to 69 families and 155 genera, among which there were 12 relativly big families with more than 4 species, 124 genera with single species, 183 species woody plants and 45 species herbaceous plants, and there were 32 tropic- areal genera, 95 temperate-areal genera, 14 widespread genera and 14 genera endemic to China. There were some compostion characteristics of the seed plant flora of urban green space in Qingdao City, such as high species diversity, many woody plant species, high differentiation in genera and species level, high areal-type diversity of genera, many temperate-areal genera and genera endemic to China.
