摘　　要：The research took different forest communities in Wenchang Satellite Launch Center as the research object and selected 8 forests to explore species diversity, evenness, and dominance of forests. The results showed that species diversity tended to be volatile upon forest communities; semi-mangrove species was the richest, as high as 2.38, followed by natural secondary forest and mixed forests. Plant evenness from high to low was as follows： herbaceous layer〉shrub layer〉tree layer. Natural secondary forest was higher in canopy density, and fewer in herbaceous plants; diversity and evenness were lower than shrub layer. Mangrove forests held lower dominance, and dominance showed insignificant differences among species.以文昌航天发射缓冲区不同森林群落为研究对象,选择8个不同植被类型,分别设置1 hm2固定大样地,对森林植物群落的多样性、森林植物群落的物种均匀度、森林植物群落的物种优势度进行观测。结果表明:不同森林群落乔木层物种多样性差异显著,半红树林群落树种种类最高,物种多样性最高达到2.38,其次分别是天然次生林和人工混交林;不同森林群落中不同层次植物均匀度总体表现出草本层>灌木层>乔木层的规律,但天然次生林由于郁闭度较高,林下草本较灌木少,多样性和均匀度均小于灌木层;红树林物种优势度最小,各物种优势差异不显著。
