摘要:

以上海环城绿带为研究区域, 对其林下乡土草本植物分布现状进行调查及编目汇总. 结果表明, 目前绿带内共有乡土草本植物35科85属111种, 分别占上海现存草本植物的70.00%, 45.70%和36.63%, 其中以单种科、寡种科居多; 地 理成分呈明显温带性质, 并兼具热带亲缘性; 调查中共出现7种生长型的草本,
生活型分析表明多年生与一年生草本比例相近, 其比例可能受人为干扰的影响;  此外, 本文对乡土草本植物在城市绿化建设中的应用进行了分析.

Abstract:

An investigation on the native herbs under the forest of Shanghai Green Belt was conducted in the paper. The result showed that the native herbs recorded in the study area included 111 species, 85 genera and 35 families, which accounted for 36.63%, 45.70% and 70.00% of Shanghai existing herb flora respectively. Most of the herbs belonged to monotypic or oligotypic families. On the geographical elements, the flora showed temperate characteristics and transition to subtropics; there were 7 life form types and the perennial herbs and annual herbs took similar proportion of all species recorded, which could be affected by human disturbance. The application potential of native herbs in urban green engineering were also proposed in the paper.
