摘　　要：应用植物区系地理学的基本原理,采用样方调查和标本采集等方法,对天津市滨海新区湿地植被的科、属、种和地理成分进行了统计分析,结果表明,该区植物共有46科135属232种。优势科现象明显,单种属数量多,其中菊科(Compositae),禾本科(Gramineae),豆科(Leguminosae),藜科(Chenopodiaceae),蓼科(Po-lygonaceae)等5个较大科的种子植物构成了天津滨海新区湿地植物区系的主体。研究区域内湿地植物区系成分中世界分布属为多,达38属,占属总数的28.36%,这在一定程度上反映了湿地植被的隐域性特征;其次是泛热带分布和北温带分布,分别占属总数的20.90%和15.67%;盐生植物占有明显优势。Using the principle of geobotany and the sampling methods and specimen collection, the areal-types of families and genera and the geographic elements of genera are analyzed through primary survey of the plants in Tianjin Binhai New Area. The investigated 232 species belong to 46 families and 135 genera, indica- ting edificators, dominant species, and main accompanying species. Among these plants, Compositae, Gra- mineae, Leguminosae, Chenopodiaceae and Polygonaceac are of most importance. In view of the plant mor- phological characteristics, the wetland plants in the area have 14 areal-types, among which 38 genera occup- ying 28.36% of the total belong to cosmopolitan-areal type and this apparently indicates that the wetland plants are universal in geographical distribution. Pantropic-areal types and north temperate-areal types occupy 20.90% and 15.67% of the total, respectively. The halophytes have distinct advantages. K
