摘　　要：研究以崇明东滩湿地公园内的253个样地为对象进行植物群落结构的调查及分析。结果表明:(1)水平结构上,有木本植物86种,隶属于47科70属,重要值较高的有19种,常绿与落叶树种的比值为0.56:1,乡土种和外来种分别占32.56%和67.44%,乔木树种平均胸径为8.64cm,77.27%集中在5～15cm;(2)垂直结构上,公园的乔灌草比为14.52:14.97:48.83:100,49.01%的样方为二层结构;(3)群落季相和健康状况上,43.08%的样方仅在2个季节有景可观,平均生长势好(4～5)和差(1～2)的植物分别占24.42%和20.93%。在此基础上分析了典型植物群落,并提出今后滨海盐碱地公园绿化的优化对策。The study investigated and analyzed plant community structure of 253 samples in Dongtan wetland park.The results indicated：（1）on horizontal structure,there were 86 species of woody plant belonging to 47 families,70 genera,among which 19 species were with high important values,the ratio was 0.56：1 between evergreen and deciduous trees,local and exotic species account for 32.56% and 67.44% respectively,the average breast-height diameter of trees was 8.64 cm,and 77.27% of trees had 5-15 cm breast-height diameter.（2）On vertical structure,the arbor-shrub-grass ratio was 14.52：14.97：48.83：100,49.01% of samples were two-layer structure.（3）43.08% of samples had plant scenery only for two seasons,plant with good（4-5） and bad（1-2） average growth potential account for 24.42% and 20.93% respectively.On this basis,typical plant communities were analyzed,measures to optimize park greening in saline land of coastal areas were suggested.
