中文摘要：

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。

英文摘要：

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.
