摘要
根据吉林省西北部草原4种坡度和3种抽样比例的达乌尔黄鼠密度调查资料,利用双因素有交互作用的方差分析,得到坡度与抽样方法独立(P<0.50)。利用双因素方差分析,得到不同抽样比例间的差异不显著(P>0.50),坡度间的差异极为显著(P<0.001)。用最小显著差数法检验,得到坡脚与其它3种坡度间的鼠密度差异极为显著(P<0.001),缓坡、坡顶和坡底的鼠密度差异不显著(P>0.10)。给出了坡度X与鼠密度Y的回归方程Y=0.8688+0.3209X(P<0.05)。
According to the collected data in the northwest part grassland of Jilin Province,the bifactor interaction analysis of variance is conducted to independence between four slopes and three sampling methods of Citellus dauricus population (P>0. 50). And again,the bifactor analysis of variance is obtained to not significant difference among the populations for three sampling methods (P>0. 50), and very significant difference among the four slopes (P<0. 001). Using to the least significant difference method,we are known,the difference of population are existed between the foot of a slope and the other slopes,respectively (P<0. 001),and the difference are not existed among the slow slope,the top of a slope and bottom (P>0. 10). Finally,the regression equation between the slope and population is obtained.
