摘要
通过对新疆昌吉州荒漠林鼠类危害及鼠类群落结构的调查,摸清了主要鼠种、数量及与梭梭被害率的关系。荒漠林区夜行鼠捕获率为10.16%(1199/11790),其中子午沙鼠Meriones meridianus占总捕获数量的81.65%。大沙鼠Rhombomys opimus密度、洞群密度和洞群覆盖率与梭梭被害率的关系呈倒"V"字形曲线,子午沙鼠、三趾跳鼠Dipus sagitt与梭梭被害率相关性不明显。建议将大沙鼠密度、洞群密度和洞群覆盖率列入大沙鼠监测调查方法和梭梭被害后是否需要采取防治措施的参考指标。
To explore the rodent species, population numbers and their relationship with damage rate on Haloxylon ammodendrom, rodent pests and community structure were investigated in Changji, Xinjiang. The capture rate was 10. 16% （ 1 199/11 790） ,and Meriones meridianus accounted for 81.65% of the total. The relatively density of Rhombomys opimus, mousehole density, mousehole coverage correlated significantly with the damage rate on H. ammodendrom while the number of the dominant species M. meridianus was irrelevant to damage rate on H. ammodendrom. We suggest the relatively density of R. opimus, mousehole density and mousehole coverag as the important reference indexes for rodent control and management strategies.
