摘要: 根据对前联邦德国卡尔斯鲁厄市城市自生植被的调查资料,分析了城市植物区系的特征及其与人类活动影响的关系。结论为:①城市植物区系在优势科组成和生态特征方面与其所在地区自然植被明显不同,并在城市之间表现出较大的相似性;②人类活动和城市热岛效应对城市植物区系及其生态特征的作用明显;③城市土地利用和城市绿地管理对许多物种的生存构成威胁

Abstract: Based on the data of spontaneous urban vegetation,the human impacts on urban flora have been discussed in this paper. The conclusions are: (a)As a result of human activity,the urban flora with regard to its spectrum of dominant families is different from that of natural vegetation,but shows rather similar characters among different cities.(b)The ecological characters of the urban flora are strongly influenced by the urban climate and soil. (c)The expand of urban land use and its influence on urban habitats as well as some measures for greenery patches management are threatening the existence of some species in the urban area.

Key words: urban, land use, human impact, flora
