Abstract:Using the principle of geobotany and the sampling methods and specimen collection, the area-ltypes 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, indicating edificators, dominant species, and main accompanying species. A mong these plants, Comp ositae, Gramineae, Leguminosae, Chenop odiaceae and Poly gonaceac are of most importance. In view of the plant morphological characteristics, thew etland plants in the area have 14 area-lty pes, among which 38 genera occupying 28. 36% of the total belong to cosmopolitan-areal type and this apparently indicates that thew etland plants are universal in geographical distribution. Pantro pic-areal types and north temperate-areal types occupy 20. 90% and 15. 67% of the total,respectively. The halophytes have distinct advantages.
