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11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11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。
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 11 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 Region 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 11 administrative areas of Yellow River wetland in Ningxia was analyzed. The relationship between zoogeographical environments and its biodiversity was discussed.
