Dynamic Analyzing and Simulating Service Function of the Eco-Economy System

The service function of the eco-economy model which is three classifi ed,i.e.,planting,breeding and hunting is fi rst put forward.The production of the three activities and its influence mechanic on the species’ variety are set forth.At the same time,the effects of the three activities of human on the ecosystem service function are simulated dynamically,and the results show that at present,the value of ecosystem service function is at the maximum,which means that it is on the critical point of wild animal living,and human beings must control our behaviors.
