The Coordinated Development of the Global Ecological System

It is of great value to provide sufficient food and energy, meanwhile ensure the sustainable use of resources and the good maintenance of ecological environment under the pressure of rapid population growth and rapid economic development. Therefore, a dynamic global network model of the global ecosystem is built in this paper. Seven elements are taken into consideration and regarded as the macro nodes. These nodes are connected by directed edges, representing the correlated relationships. Symbiosis theory is used to analyze the network model. The results show that the model can effectively measure the related internal coordination degree of subsystems.
