| Man-land relationship is objective. The relations are one. of the core fields in which geography studies. With the development of productivity and the scientific and technological progress, the relations are studied and deepened by people, thinking from philosophy to practice field.This paper studies man-land relationship areal system by using human geography, ecology, regional economics, the theory of the modern system and flow economics theory This paper thinks that the areal system is an organism, formed by natural system, economic system and social system. The subsystems are connected by key element. In fact, through the flow and association of the key elements, a subsystem is connected with each other, restricts interaction each other. The key elements are the bridge that inside and external world contact together. So, the key element is the base of research.The key elements flow and fabricate within the region system and external world, which produce different function ways, namely the relation. The association of the key elements forms the structure system. The inside structure system includes ecological environment structure, economic structure and social structure. The function of the region system is limited by the structure in the system. So, starting with the key element, we study the evolution of the region system through the structure that key element form.This paper divides five chapters. Chapter one is the understanding of the relation and the areal system and reviewing history studied, and then defines the concept and puts forward the meaning of man-land relationship.Chapter two is the studying on key element of areal system, classifying the key element, summarizing seven major characteristics of the key element, explaining the mechanism on the function between the key elements, explaining the reason for influencing the factor mobility, summarizing six laws of the factor mobility, pointing out its meaning.Chapter three analyses the structure of areal system, proposing basic understanding, pointing out ecological environment structure, economic structure and social structure which are focal points. The element structure constitute, research contents, research meaning of these three pieces have been analysed.Chapter four is the studying on man-land relationship areal system. Firstly, the paper analyses mapped relationship among three kinds of structure of areal system. Then constructs academic framework of man-land relationship. Lastly, probes the type of man-land relationship areal system in the world.Chapter five carries on the positive research to Jilin Province, analyzing key elements of areal system of Jilin province, then analyzing and appraising the ecological environment structure, economic structure and social structure of Jilin Province, then putting forward the countermeasures and suggestion. |
