【摘要】 本文对西双版纳热带雨林片断化对榕树和榕小蜂群落多样性的影响进行了研究,样点内共采集和观察榕树16种,123株;榕小蜂18种,20728号。研究表明热带雨林片断化使榕小蜂和榕树的种类呈明显下降趋势;常见种的种群数量增多,优势种和特有种的种数量减少,片断热带雨林面积的大小对二者的物种数和个体数有明显的影响。要保护和发展榕树及传粉昆虫榕小蜂,首要任务是保护和恢复以森林为主的热带雨林生态系统。更多还原

【Abstract】 Fragmentation of tropical rainforest has affected on the community diversity of fig and fig wasp. This study collected and observed 123 fig trees which consist of 18 species, and 20 728 fig wasps which consist of 18 species in Xishuangbanna. The result indicates that the fragmentation of tropical rainforest is attributable to the diminish of species numbers of figs and fig wasps, increasing of common species population, and population reduction of dominant species and species--specific figs and fig wasps. Fragmented area of tropical rainforest has significant effect on species number and individual number of both fig and fig wasp. This paper suggests that basic work of conversing and developing figs and fig Wasps is to converse and revive the tropical rainforest ecosystem.更多还原
