    摘要:海漂植物是滨海植物群落的重要组成部分,具有较高的观赏价值和生态价值。通过野外调查与文献查阅,对海南省海口市、文昌市、三亚市等海岸带的海漂植物组成、观赏特性、生态适应性,以及园林应用情况进行调查与分析。结果表明:海南岛滨海地区海漂植物包含35科52属59种,其中乔木所占比重较大,共31种,占总数的52.5%。灌木、藤本、草本总数分别为12种、7种和9种;按生境分为滨海沙岸、岩岸、红树林、海岸林4个类型,有些植物具有多种生境适应性;采用层次分析法(AHP)构建海漂植物园林景观应用综合评价体系,并根据评价结果,筛选出30种观赏价值高、适应性强的种类,推荐应用于园林景观营造以及滨海生态恢复中。

    Abstract:The sea drift plant is a critical component of seashore plant community, which has high ornamental and ecological value. In this study, the species composition, ornamental characteristics, ecological adaptability, and landscaping application of the sea drift plants in Haikou, Wenchang, Sanya and other seashore zones in Hainan island were investigated and analyzed through field expedition and literature consulting. The results showed that there were 59 species of sea drift plants in Hainan Island’s seashore region, which belonged to 52 genera in 35 families. Among those 59 species, 31 were arbor, which took a dominant proportion of 52.5%. The species numbers of shrub, liana, and herb were 12, 7 and 9, respectively. According to their habitat type, the 59 species could be classified into 4 community types including seashore ammochthad, rocky shore, mangrove and coastal forest. And some of them had occurred in the multiple habitat. The analytic hierarchy process (AHP) was used to construct a comprehensive evaluation system for the landscape application of sea drift plants. According to the evaluation results, 30 species with high ornamental value and environmental adaptability were selected and recommended to landscape construction and seashore ecological restoration.
