| 摘 要： | 本文给出了判断昆虫种群空间分布型时,Iwao模型中α、β允许偏离范围的一种新的统计推断方法。提出用t检验法即分别对α与0（当A=0）、β与1（当B=1）间的偏离度进行t检验。上式中,α、β为IwaoM—M回归模型中的系数,n为建模所用的样地数,M_i为第i个样地的平均拥挤度,M_i为第i个样地的平均密度。应用两个实例进行了检验,从而验证了该方法的适用性和可行性。此外,还讨论了该法适用的条件。 |

| Abstract: | The paper gives a new statistical method that decide the allowable deviation range in Iwao M*-M model when used to judge the spatial distribution in which T-test method has been given, that is:to decide a and o (when A = 0), β and 1 (when B = l) respectively, where a and (3 are coefficient in Iwao M*-M model, Mi* is mean crowd degree for the i-thplot, Mi is mean density degree for the i-th plot. Two examples have been te-_ sted and the feasibility and condition of the method have been discussed. |
