| 本文分析塔额盆地草原蝗虫的生态位，旨在为当地的蝗灾监控、治理及生态平衡保护提供理论依据。本研究对塔额盆地冲积平原、山前洪积倾斜平原、山地3种地形的草原蝗虫的空间生态位进行分析，统计得出了蝗虫优势度、群落组成差异、Levins生态位宽度和Shannon生态位宽度、Pianka生态位重叠等相关参数。结果表明：3种地形共采集蝗虫6科19种1 023头，不同地形优势种、常见种及稀有种均存在差异。山地与山前洪积倾斜平原、冲积平原的蝗虫群落组成差异较大。黑条小车蝗Oedaleus decorus decorus、蓝胫戟纹蝗Dociostaurus tartarus、意大利蝗Calliptamus italicus、红胫戟纹蝗Dociostaurus kraussi kraussi、伪星翅蝗Calliptamus coelesyriensis的生态位较宽且与其他蝗虫存在生态位重叠。塔额盆地草原蝗虫发生种类较多，绝大部分优势种蝗虫对空间资源的利用能力较强、竞争较激烈，对优势危害种加大监测力度，而针对山前洪积倾斜平原中的稀有种类，应加以保护以确保生物多样性。 |

| This paper analyzes the ecological niche of grasshoppers in the grassland of Tacheng-Emin Basin, in order to provide a theoretical basis for grasshopper disaster monitoring, management and ecological balance protection. In this study, the spatial ecological niche of grasshoppers in the alluvial plain, piedmont pluvial sloping plain and mountain area in the Tacheng-Emin Basin was analyzed. The related parameters such as grasshopper dominance, community composition difference, Levins niche width, Shannon niche width, and Pianka niche overlap were obtained. The results showed that: A total of 1 023 grasshoppers of 19 species and 6 families were collected in the three terrains. There were differences in dominant species, common species, and rare species in different terrains. The grasshopper community composition was significantly different between alluvial plain and piedmont pluvial sloping plain and mountain area. Oedaleus decorus decorus, Dociostaurus tartarus, Calliptamus italicus, Dociostaurus kraussi kraussi and Calliptamus coelesyriensis had wide ecological niches and overlapped with other grasshoppers. There were many species of grassland grasshoppers in Tacheng-Emin Basin, and most dominant species of grasshoppers had strong ability to utilize spatial resources and fierce competition. More efforts should be made to monitor the dominant hazard species, and the rare species in the piedmont pluvial sloping plain of foremountain diluvial should be protected to ensure biodiversity. |
