摘要: 报道了围栏封育后羊草草原和大针茅草原蝗虫丰富度的变化,比较了蝗虫在羊草草原和大针茅草原的发生特点.结果表明,以毛足棒角蝗为主导种的大针茅草原蝗虫生物量是以小翅雏蝗为主导种的羊草草原蝗虫生物量的4~5倍;围栏封育后,羊草草原蝗虫的生物量增加24%,而大针茅蝗虫的生物量略有减少;围栏措施改变蝗虫的结构组成,使毛足棒角蝗、鼓翅皱膝蝗、宽须蚁蝗、亚洲小车蝗等旱生和中旱生的地栖或兼栖偏地栖种类的发生减少,条纹鸣蝗、小翅雏蝗、红腹牧草蝗等中生的植栖或兼栖偏植栖种类增加,短星翅蝗及狭翅雏蝗的生物量在大针茅草原增加而在羊草草原减少.

Abstract: Grasshopper abundance was compered between Aneurolepidium chinense and Stipa grandis steppes which were grazed and excluded from livestock. The abundance of Dasyhippus barbipes dominated on Stipa grandis steppe is 4~5 times as high as that of Chorthippus dubius on Aneurolepidium chinense steppe. After exclusion from livestock for 13 years, the total biomass of grasshopper is increased by 24% on Anearolepidium chinense steppe, and is decreased a little on Stipa grandis steppe. The livestock exclusion leads to changes in structure and compeition of grasshoppers. The abundance of Angaracris barabensis, Dasyhippus barbipes, Myrmeleote ttix palpalis and Oedaleus asiaticus is decreased and that of Chorthippus fallax, Mongolotet tix japonicus vittatus and Omocestus haemorrhoidalis is increased. The biomass of Calliptamus abbreviatus and Chorthippus dubius is increased on Aneurolepidium chinense steppe, but decreased on Stipa grandis steppe.
