【摘要】 系统研究了团泊洼鸟类自然保护区的蛾类,已知16科123属160种,并对其多样性作了分析研究,结果表明,种多度关系接近于对数级数模型,物种少而优势种得到了大的发展,多样性指数与均匀度不相一致,且略表现为负相关(r=-O.5960),而与丰富度一致(r=O.8742),说明团泊洼鸟类自然保护区的蛾类群落较不稳定,这与近年来湿地的退化以及人为活动有关。更多还原

【Abstract】 Tuanbowa Birds Nature Reserve is situated in the south of Tianjin (38°51′-38°58′N,117°9′- 117?°30′E). A Study on the moth community and its diversity in this area was carried out from June 20 to October 5 in 2001 and from April 20 to October 20 in 2002. A total of 160 moth species belonging to 16 families and 123 genera were collected and their diversity was analyzed. The results showed the curve of the moth species-abundance was fit for the niche pre-emption hypothesis; the variety of species was not rich in Tuanbowa Birds Nature Reserve, but the dominant species were developed; no correlations have been fond between indices of divesity and evenness (r=-0.5960), and indices of diversity with richness are correlated (r=0.8742). These indicated that the moth community was not stable in Tuanbowa, which was closely related to the serious degeneration of the wetland environment and the human activities.更多还原
