海南岛西海岸植物群落的初探

海南岛西海岸野生种子植物约1520种（含变种、亚种）、686属、161科。本区系热带性质明显，热带分布属占总属数（除去世界属和外来属）的93%以上，热带分布种超过总种数（除去广布种和外来种）的80% 。植物群落约250个，其中单优种群落约118个。多数群落优势种不明显，群落主要由共建种构建。群落特征以共建种群落多，单优种群落少，多数群落分布规模小，常以灌木丛、刺灌丛或草甸状草丛及分布非地带性为主要特征；西海岸资源植物丰富，但几乎无蕴藏量，仍有不少资源植物很有开发潜力。

Preliminary Studies on the Western Coastal Plant Communities of Hainan Island

The spermatophyte flora consists of 1520 species in 686 genera and 161 families. The western coastal flora is explicitly of tropics in nature.The statistics of distributional patterns of taxa shows that genera and species of tropical distribution take up more than 93% and 80% of the total taxa of the flora respectively .There are about 250 plant communities, 118 of which are monodominant .The communities are characterized by co-edificatoes more than monodominant species in the comunities, distribution on a small scale for the most of plant communities, thorny fruticeta, shrublands, herbages. and azonation. On the western coast there are abundant in resource plant species, poor in storage quantity, there are still some plants for promising development and utilization.
