Abstract: Based on the integrity of system and relationship between various subsystems and employing transitionalstructural model,the multilevel gradient structures of system are found from temporal and spatial dimen-sions.According to the dissipate and reproductive features of ecosystem and using input-output correla-tion table,the mathematical models of material,energy and value flows are established.This approachprovides an effective means for the prediction,programming and management of production.

Key words: Anguilla japonica, aquaculture model, morphological and quality traits, multivariate analysis.
