中文摘要：宁夏黄河湿地现已知有44 种蝗虫, 隶属2 总科8 科24 属, 占全自治区蝗虫总种数的50.57%。湿地蝗虫在种类组成上以蝗总科中的斑翅蝗科为优势类群, 共计12 属15 种, 占总种数的34.09%。网翅蝗科次之, 共计3 属1.种, 占总种数的25%。区系成分分析结果表明, 宁夏黄河湿地蝗虫完全为古北界区系成分。在中国地理区划中有17 个区系型, 以蒙新区特有种所占比例最高, 计17 种, 占总种数的38.64%。其次为蒙新区-青藏区系型, 计4 种, 占9.09%。以宁夏黄河湿地1.个自然行政地理区划为分类单元, 对其种类生态地理分布进行聚类分析, 探讨了地理生态环境与生物物种多样性之间的关系。
英文摘要：The composition and characters of the grasshopper fauna in Yellow River wetland of Ningxia were studied. Forty-four species of grasshoppers were collected, which belong to 2 superfamilies, 8 families and 24 genera (50.57% of the grasshoppers known in Ningxia). The family Oedipodidae is the predominant group ( 12 genera and 15 species), occupying 34.09% of the total species. The family Arcypteridae ( 3 genera and 1.species) is the next, accounting for 25%. The faunal analysis shows that all species belong to Palaearctic species. In the zoogeographic regions of China, 17 distribution patterns can be catalogued. The Mengxin Reg ion and Mengxin-Qingzang Region are predominant types for these distribution patterns of Ningxia, and the endemic species of the former accounts for 38.64% ( 17 species) of the total species and the latter for 9.09% (4 species). By using DPS software, a cluster of grasshoppers in 1.administrative areas of Yellow River wetland in Ningxia was analyzed. The relationship between zoogeographical environments and its biodiversity was discussed.
