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。 We have since 1983, in Maoershan soil fauna research data obtained during the process, IBMPC microcomputer processing analysis. Based on the concept of sample matrix, many-to-many regression method was used to analyze the distribution of population, the relationship between population and environment, and the maximum number of soil animal population in this area was estimated. A knife-and-knife method was used to answer this question, indicating that there were 86 species of soil animals and 9 species of single species.
