摘　　要：为探究宁夏草原蝗虫群落优势种、指示种及其对植被不同类群的响应关系,2019—2020年在宁夏温性草甸草原、温性草原、温性荒漠草原和温性草原化荒漠选取典型调查样地,对不同草原类蝗虫优势种、指示种及其对不同植被群落的响应关系进行了分析研究。结果显示:白纹雏蝗(Chorthippus albonemus)作为宁夏四类草原共同优势种,与禾本科和菊科盖度、高度、生物量之间呈显著正相关(P<0.05);短星翅蝗(Calliptamus abbreviatus),亚洲小车蝗(Oedaleus asiaticus)和赤翅皱膝蝗(Angaracris rhodopa)作为温性草原指示种蝗虫,与禾本科植被盖度、频度和生物量呈显著正相关(P<0.05);红缘短鼻蝗(Filchnerella rubimargina)和黑腿星翅蝗(Calliptamus barbarus)作为温性草原化荒漠的优势种,与其他科植被盖度和生物量呈显著负相关关系(P<0.05)。因此,科学监测禾本科与菊科植被分布较广的草原类型将有助于蝗虫有效监测和及时防控,进一步为草原管理和蝗虫可持续治理提供支撑。In order to explore the dominant species and indicator species of grasshopper community in Ningxia steppe and their response relationships to different vegetation groups,typical survey plots were selected in temperate meadow steppe,temperate steppe,temperate desert steppe and temperate steppe desert in Ningxia from 2019 to 2020.The dominant species and indicator species of different steppe grasshoppers and their response relationships to different vegetation communities were analyzed.The results showed that C.albonemus,as the common dominant species of the four steppe species in Ningxia,was significantly positively correlated to the coverage,height and biomass of Poaceae and Asteraceae(P<0.05).C.abbreviatus,O.asiaticus and A.rhodopa were the indicator species of temperate steppe,and were significantly positively correlated to gramineous vegetation coverage,frequency and biomass(P<0.05),and F.rubimargina and C.barbarus,as the dominant species in temperate steppe desert,were negatively correlated to vegetation coverage and biomass of other families(P<0.05).Therefore,scientific monitoring of steppe types with wide distribution of grass and Asteraceae vegetation will help effective monitor and timely control of grasshoppers,and further provide support for steppe management and integrated grasshopper control.
