摘　　要：2008年7月～2009年9月对海南岛自然保护区的鱼类组成与生境调查,结果表明,鱼类群落中以山区溪流性小型鱼类为主;鲤科鱼类是其中最大的类群,构成鱼类区系成分的主体;万泉河水系有27种,多于昌化江水系的25种和南渡江水系的21种,植物食性占12.82%,动物食性占23.08%,杂食性占43.59%,碎屑食性占20.51%。生境丧失和过度捕捞是造成鱼类多样性下降的主要原因。The fish composition and habitatsin Hainan is land nature Reserve were surveyed from July 2008 to September 2009.The results showed that most of them were small-size fishes in mountain brooks.Cyprinids were the main component of this fish fauna.Various diversity indices revealed that were the best preserved sites with high fish diversity.The fish stocks of the nature reserve belonged to different ecological types in their migration,feeding and inhabitation.Fish communities were dominated by sedentary species of the community,omnivore species and sub-stratum species.Among them,there were 12.82% herbivore,23.08% carnivore,43.59% omnivorous fish and 20.51% detritus fish.The habitat loss and overfishing were main causes that caused the diversity decrease of fishes.
