东北地区不同生境内蝗虫区系的比较

Faunal composition of grasshopper in different habitats of Northeast China?

经过多年的调查,并参考其他研究成果,在所设的8个样点中统计出蝗虫7科,39属,107种。分析了东北地区蝗虫的群落结构、各蝗种的区系地理成分、种属分配,并讨论了该区蝗虫的地理分布关系等。结果表明,东北地区的蝗虫古北种占绝对优势,约占总种类数的87.85%,在所调查的8种类型的生境中,长白山地区的蝗虫种类最为丰富,向海自然保护区的蝗虫种类最少,并且和其他各生境蝗虫组成的相似性指数均较低。

Based on our investigation and relevant references, a total of 107 species of grasshopper, belonging to 7 families and 39 genera, was recorded in 8 sampling sites of Northeast China. The analysis of grasshopper community structure, faunal composition, and geographical distribution suggested that Palaearctic species were dominant in Northeast China, occupying 87.85 % of the total. In the 8 types of habitats, Changbai Mountain had the most abundant faunal composition of grasshopper, whereas Xianghai Natural Reserve had the least one, Compared to other habitats, Xianghai Natural Reserve had a lower similarity index.
