Abstract:

Based on the theory of ecology and previous experience,system engineering method was used to construct a model to analyse hierarchy structure of forest site types.In this method,referential theories and experience were transformed into distal data,then sort into certain order,then determine the effect of site conditions on ecological factors in turn,thereby the growth of trees was affected.On these grounds,the classification system of genesis of site hierarchy structure was established so that forest sites were zoned and sorted.

Key words: Hierarchy analysis, Structure model, Genesis, Zoning and sorting of forest sites
