中文摘要：

通过相关资料查阅,建立了上海地区65科284属534种乡土陆生草本植物名录,并对大金山岛、佘山和上海市域＂城区—城郊—郊县＂城乡梯度上不同土地利用类型中野生草本植物的分布现状进行了调查,阐明了城市化影响下陆生草本植物的多样性格局.在分析物种的科属组成、地理成分、生活型和分布现状的基础上,阐明了地理位置、面积大小、生境类型及城市化程度对野生草本植物物种组成的决定作用;根据分布区域和物种对环境的适应特征,将上海地区乡土陆生草本植物划分为广适型草、都市型草、城郊型草、郊县型草和山野型草5个类型;对乡土草本植物在城市绿化建设中的应用进行了展望.

英文摘要：

Through consulting related data,a list of 534 native terrestrial wild plants species in Shanghai was built,which belonged to 65 families and 284 genera,and the distribution status of wild plants in different lands was investigated along a ＂urban-suburban-rural＂ gradient in Shanghai area,Sheshan mountain and Dajinshan island,expounding the diversity of terrestrial wild plants influenced by urbanization.By analyzing the families and genera compositions,areal types,life form and distribution status of species,the decisive role of the geographic location,size,habitat type and degree of urbanization for the composition of wild plants was illustrated.According to the distribution of species and adaptation to the environment,the native terrestrial wild plants in Shanghai were divided into five weeds types,such as eurytopic type,urban type,suburban type,suburb type and wild type.The significance and application of native wild plants in urban greening of Shanghai were analyzed.
