摘要: 本文通过对杭州地区禾本科禾亚科植物的调查、采集、鉴定,取得结果为本地区的禾亚科植物有157种(其中有20个变种1变型),隶属于81属,12族.以族、属、种为单位.对本地区禾亚科植物的种类组成及分布型等方面进行了分析,结果表明:(1)本地区禾亚科植物各族间属、种数量相差悬殊,与地带性和族的地理分布有关.(2)属以单种或寡种为主,表明本地区植物区系的多样性.(3)无特有属、种,反映该分布区地形较为单一((4)属的分布区类型多样,具有热带到温带分布的过渡性.(5)植物区系组成复杂,种的分布以全国分布型、长江以南广布型和华东分布型占主要地位.

Abstract: In this paper by investigating,collecting and identifing Subfamily Agrostidoideae (Gramineae) inHangzhou district .there are 157 taxa of Agrostidoideae. Among these taxa there are 136 species,20 va-rieties and 1 form which belong to 81 genera and 12 tribs. Species component and distribuion on patternof Agrostidoideae in this district analysed in the unit of trib,genus and species,the results are summa-rized as follows: (1) The quantities of the genus and species among tribs are great disparity, which relate to tonalityand geographic distribution of tribs. (2) The floristic diversity is revealed by the main component of monotypic and oligotypic genera. (3) None of endemic genera and species reflect that the topography of the distribution area is rela-tively unitary. (4)Distribution diversity represents a transition at pattern of distribution from tropical to temper-ate. (5)The floristic elements are complex and mainly composed of wide distribution of China,widedistribution to the south of the Yangtze River and the distribution of East China.
