摘要: 系统调查研究了天津七里海湿地的蛾类,已知19科153属198种,并对其多样性作了分析。结果表明,种多度关系符合对数正态分布模型。但多样性指数与均匀度不相一致(r =-0.47),而与物种丰富度一致(r=0.95)。研究认为七里海湿地环境条件比较好,但有退化的趋势。

Abstract: The Qilihai wetland is situated in the northeast of Tianjin (39°16′-39°20′N, 117°29′-117°39′E). An investigation on the diversity of its moth community was carried out from June 21 to October 6 in 2001 and from April 21 to October 21 in 2002. A total of 198 moth species belonging to 153 genera in 19 families were collected. The results show that the curve of the moth speciesabundancewas in accordance with the lognormal hypothesis. However, no significant correlation was found between indices of diversity and evenness (r=-0.47) but Indices of diversity and richness was significantly correlated (r=0.95). This suggests that the environmental quality of the Qilihai wetland be deteriorating.
