摘要
The model of interspecific association index was constructed in this paper. It is proved that the classical interspecific association statistic is the special case of this model. The derivation of this paper got the unification between interspecific association measurement and its statistic, and between its qualitative analysis and quantitative analysis. The essence of interspecific association index was opened out and the enactment of interspecific association index was developed. Four part specific association indices were constructed on this base, all of the specific association indices were computed respectively to the different radius of sample circle by the permanent sample plot data in Moarshan National Forest Park, Heilongjiang Province, P. R. China. The fourth index was less affected by the size of sample circle, was steady and widely practical.
