| 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8.64 cm，77.27%集中在5~15 cm；（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。

| Abstract: | 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. |
