Abstract: The methods of investigation are been discussed for forecasting Brandt's vole populations.There are four methods usually are used.They are(1) captured-recapured method,(2) all captured inplot,(3) numbers of burrow method and(4) trap day method.The maximum coefficient of relation in themare between(1) and(2) [r = 0.7599, P<0.05], the second is between(1) and(3) [r = 0.5146, P<0.05], the smallest is(1) and(4).It is a suggest that all captured in plot can be applied for forest wherehaving better condition.The method of count number burrows can be used if it does no require more pre-cision of information of the population.Trap day method is not sensitive for the dynamic of the population,but the data can be used compare populations in geo-range.

摘要： 本文探讨了常用的四种调查方法,即标记流放法、定面积捕尽法、洞口计数法和铗日法对布氏田鼠数量测报的效果。结果标记法相关最高的是捕尽法(r＝0,7599,P<0.05),其次为洞口法(r=0.5146,P<0.05),铗日法最低(r=0.2682,P<0.05)。建议有条件时可应用捕尽法。如对数量精度和种群信息要求较低者,可使用洞口法。铁日法对于种群变动的灵敏性较差,其资料可供地理范围之间的比较。
