We obtain the risk process involved in this model,the statistical properties of the surplus process,and statistical features of the claim numbers and the probability distribution of the total amount of compensation.The three types of business of the risk model is given when the number of claims obey Poisson distribution and negative binomial distribution.We make a comparison between the risk model built in the thesis and the classic risk models with independent claim numbers when the amount of claims obey Weillbull distribution and Exponential distribution.The results have a good practical significance.

其次，考虑不同险种间的相互关系，建立了一种含有主副理赔的风险分析模型；借助随机过程和经典风险理论，对该风险模型所涉及的风险过程、盈余过程的统计特性以及理赔总额的概率分布、数字特征和矩母函数进行解析研究，给出了主理赔次数服从泊松分布和负二项分布的这种风险模型的具体实例，并在理赔额变量服从Weillbul分布和Exponential分布的情况下，把文中所建风险模型和理赔次数相互独立的风险模型作了比较，所得结果有很好的现实意义。

In Zigui Country, the numbers of Nematoda, Acarina and Collembola individuals were not much affected by habitat and elevation, while in Wanxian Country, the numbers of Acarina and Collembola were by elevation. In Shennongjia region, distribution of Nematoda varied significantly with vegetation. Acarina and Collembola were widely distributed in various soil layers under different vegetation, whereas the number of Acarina in the litter layer varied significantly with habitat and elevation.
