The Law Of Entropy And Population Distribution

The dynamic Mechanism of Migration and urbanization is a key issue in the research of Migration and urbanization. The thesis makes out a new theory of dynamic Mechanism of Migration and urbanization based on the Entropy law and dissipative structure theory. The thesis consists of six chapters, which basic framework is as follows:Part one is the introduction of the thesis. In this part, the author mainly explains the research purpose, selected title angle, research approach, research range and frame, innovation and Insufficient.In the second part, the author summarizes existing theory about population migration and urbanization dynamic mechanism as six theories and comments their Advantages and disadvantages briefly.The third part of the article has analyzed the possibility that uses concept and law of natural science to study the social science problem at first. Subsequently, the author make a brief introduction to the entropy law and dissipate structural theory and expound the fact that the life entity and the human society both are Typical dissipation structural which determine their exist and function keep and development must Absorb energy from the external system. If regard utilizing the boundary line by mankind, the energy of the ecosystem flows and splits up for two parts: The internal energy flows and The External energy flows. The internal energy flows include the food chain energy flows and the technological chain energy flows. With scientific and technological progress, the scale and thermal efficiency of food chain energy flows and technological chain energy flows improved and the effective energy of human society increase constantly, which is being shown as progress of productivity and increase of wealth of society in realistic society.In the fourth part, the author set up a connection between population and energy through the study of population carrying capacity and...
