Abstract: The Object-Oriented Programming(OOP)technique which consists of three useful concepts andmethods,i.e.,encapsulation,inheritance and polymorphism,provides a natural path to simulatereal ecosystem.A framework of ecosystem model is constructed with OOP technique in Borland C₊₊on the basis of Palmiter model which is developed by Ladd, and part of the model shows how the dynamic pattern of palmiter population changes with biological and ecological parame-ters. The application of OOP technique in ecosystem modelling gives a broad foreground in eco-logical research and supplies a possibility to study ecological problems with " Artificial Life" on computer.

Key words: endophytic fungi, soil microbial biomass, soil enzyme, DGGE.
