Analysis of Oratosquillaorator Age Composition
This paper analyse the age makeup of Oratosquillaorator age at dalian sea entrance by use of the clustering method. According to sample and test, the distance between the old genuses and the new genuses is computed according to the clustering method of the most short distance by use of range criterion formulation and the absolute value distance formulation, and the clustering matrix is obtained. The sort of squill age is divided by intuitionistic analysis in the light of the material clustering process. The proportion of squill age range is estimated according to the relationship of the squill attribute by use of program. The last, indicate that the analysis of the makeup of the squill age and knowing the proportion of squill age range may provide the theory basis for protecting the squill resource and the fishery management, and may promote the utility with reason for the squill resource and the persistence progress, this has a ecological significance to the development of both increment and breed for squill, and to the fishery production and environment protection.
