To study human existence,the earth of human living is firstly studied. By the study of many natural phenomena on the earth,we firstly put forward the theory of earth ecosystem,expound its definition,structure,aim,function,content and significance,and illustrate the characteristics of earth ecosystem. So we found the theory of earth ecosystem,and unveil the variable processes and the operation mechanisms of earth ecosystem. We put forward the earth ecosystem and its theoretic system,which are different from the previous ＂ earth system science＂ and ＂ Gaia hypothesis＂. We consider that among each part of the environment,between environment and organism,there are organic,close and coalescent relationships,so that the earth ecosystem is able to have a sustainable development. Even if there is no life,the earth ecosystem also can control and regulate the earth changes,and possesses the stable state. Therefore,the foundation of the earth ecosystem theory is conducive to the studies of the global problems： the change processes and trends of resources,ecologies,environments,disasters,and so on.展开更多
