千山风景区蛾类多样性调查

在林内设置黑光灯,对千山风景区蛾类昆虫进行监测诱捕,统计其物种数和个体数,计算Shannon-Wiener多样性指数、Pielou均匀度指数和Berger-Parker优势度指数,并估计该地区潜在蛾类物种数。结果表明:在千山风景区共获得25科180属251种蛾类,优势科是夜蛾科、螟蛾科和卷蛾科。千山风景区蛾类Shannon-Wiener多样性指数较高,均匀度较大,而优势度则较低。千山风景区的蛾类种-多度分布为对数正态分布,蛾类估计种数为519种,优势种为三环须水螟(Mabra charonialis)。

Moth Diversity of Qianshan Scenic Areas

This study was conducted to investigate moth diversity in the forest of Qianshan Scenic Areas by setting up light trap there to monitor the moth, counting the species and individual numbers, calculating the Shannon-Wiener diversity index, Pielou evenness and Berger-Parker dominance indexes, and then estimating the potential total moth species number there by Chao-1estimator. The results indicate that a total of 633 moths were trapped, which belonged to 251 species of 180 genera of 25 families in the forest, in which the dominant families were Noctuidae, Pyralidae and Tortricidae. Moth's Shannon-Wiener diversity index and evenness were very high, while the degree of dominance was low. The estimated species of Qianshan Mountains were 519, in which the dominant species was Mabra charonialis.
