摘　　要：为建立一套适合滨海盐碱地的绿化植被综合评价指标体系,为上海和其他滨海盐碱地区绿化树种的合理选择引种及配置,也为生态工程建设和评价提供科学依据和参考。根据群落结构和功能的生态学和美学原理,在问卷调查和实地调查的基础上,结合德尔菲法、层次分析法建立包含生态、抗性和景观三大准则(13项评价因子)的指标体系。应用该体系对崇明东滩湿地公园20种植物群落进行评价、筛选和优化,推荐综合得分较高的群落有3个:湿地松+乌桕-木芙蓉+夹竹桃-马尼拉,乌桕-海滨木槿+紫穗槐+金叶接骨木-八宝景天+紫茉莉和国槐+三角枫+榔榆+朴树-紫穗槐+伞房决明-美人蕉;得分较低的群落表现出乡土树种比例小、彩叶树种应用不足、季相变化不明显等问题。Based on questionnaires and sample-plot survey, combined with analytical hierarchy process （AHP） and Delphi technique, this study established a comprehensive evaluation index system which was suitable for green vegetation in saline land of coastal areas with 13 evaluation factors belonging to three norms of ecology, resistance and landscape according to principles of ecology and aesthetics about community structure and function, in order to provide a scientific basis and reference for the rational selection, introduction and configuration of greening tree species, and then the eco-engineering construction and evaluation in Shanghai and other coastal saline areas. The system was applied in 20 selected plant communities of Dongtan wetland park to select advocated communities and optimize. Three plant communities with higher comprehensive scores were advocated： Pinus elliottii ＋Sapium sebiferum-Hibiscus mutabilis ＋Nerium indicum- Zoysia matrello, S. sebiferum-Hibiscus hamabo ＋Amorpha fruticosa ＋Sambltcus williamsii ＇Aurea＇-Hylotelephium spectabile＋Mirabilis jalapa and Sophora japonica＋Acer buergerianum＋Ulmus parvifolia＋Celtis sinensis-A, fruticosa＋Cassia corymbosa-Canna indica; plant communities with lower scores were lack of native trees, colored-leaf trees and seasonal variation and so on.
