摘  要:根据6年的调查结果,对宁波滨海维管束植物的区系与地理分布特点进行了分析.结果表明:1)宁波市共有滨海植物66科,126属,163种;2)科属统计分析表明,物种主要集中于小型科、单种属;3)植物生活型以草本植物占优势,其中又以多年生草本植物占优势;4)地理成分复杂,科级、属级、种级地理分布区类型分别是7型、13型、10型;科、属、种三级T/R值(热带/温带比例)分别为3.57、1.04、0.25,显示了强烈的热带区系亲缘及温带区系的后期影响;5)种级分析表明,与日本、中国台湾、韩国联系紧密,与印度、澳洲、地中海-西亚至中亚植物区系存在一定联系,与美洲大陆、非洲大陆的联系较弱;区域特有性明显;6)从地质、气候、化石三方面推测,宁波滨海现代植物区系最迟成形于中新世.The flora and geographical distribution of coastal vascular plants in Ningbo are summarized based on6-year investigations.The results show that there are66families,126genera and163species of coastal plants in Ningbo.The analysis of families and genera compositions indicate that the species mainly distribute in small families and monotypic genera.The herbs constitutes the majority in the life forms,in which perennial herbs is in a dominant position.The geographical components of the flora are complex and varied.The geographical distribution types of family,genus and species are7types,13types and10types,respectively.The value of T/R(the ratio of tropical and temperate floras)is3.57at the family level,1.04at the genus level,and0.25at the species level,showing a distinctive affinity for tropical floras,and imprints of temperate floras.The analysis of species level shows that it is close contact with Japan,Taiwan,South Korea,some links with India,Australia,the Mediterranean,West Asia to Central Asia,and weak links with American Continent,Africa Continent;regional characteristics are obvious.Inferred from geology,climate and fossil,it is demonstrated that the modern coastal flora forms in not later than Miocene.
