摘要
我们对1983年以来,在帽儿山地区土壤动物研究过程中获得的资料数据,在IBMPC微机上处理分析。从样本矩阵的概念出发,采用多对多的回归方法,聚类法分析了种群的分布规律,种群与环境的相关关系,并估计出该地区土壤动物种群最大数量。采用刀切法对这个问题作出回答,即出现土壤动物种数是86种,单一种数是9种。
The data collected from the Maoershan area during the study of the forest soil animal since 1983 was processed and analysed on the IBM-PC microcomputer. With the concept of sample matrix, the distribution law of the animal population and the correlationship between the population and its environment were analysed clusterly by means of multivariate regression analysis. And the maximum number of the soil animal population in local area was estimated by the Way of the Jack-knife method, which showed that the real species of soil animal is 86; the single species is 9.
