摘　　要：为了研究滨海新区湿地植物的特征和生态效益,更好的了解湿地植物群落的价值,研究了湿地植物的种类及区系组成、植物多样性及其分布、湿地植被的演替规律,研究得出本区湿地植物种类较多,共232种,科属种分布广泛,植物丰富度较高,均匀度一般,湿地植物受水盐程度影响较大,演替过程主要由水盐程度主导;水分多时向湿生水生植物演替如碱菀、芦苇等,水分少盐度高时多发生向中生盐生植物的演替如獐毛等。In order to study the characteristics of wetland plants and their ecological benefit in the Binhai New District and better understand the value of the wetland plants, the wetland plant species and their flora composition, the plant diversity and its distribution,and the wetland plant succession patterns were studied in this paper. The results showed that there are a total of 232 species of wetland plants in this area, with a large distribution in the family and genera; the abundance of plants is relatively high but the evenness level of wetland plants is low, and the wetland plant community and its vegetation succession are affected greatly by the soil moisture and salt contents; the hydrophytes and phreatophytes, such as Tripolium vulgare Nees and Phragmites,occur when the wetland community has a high water content but low salinity,and the meso-halophytes, such as Aeluropus pungens, occur when the wetland community has a high salinity but low water content.
