Based on the program of "Study on the evolution of the rural settlement system and optimization of the rural inhabitable environment in Jianghan Plain , Hubei, China" (40671050) founded by the national science foundation and on the program of " Study on the spatial structure and the towns distribution in the process of the rural urbanization" (05JJDZH232) founded by the national department of the Education. The dissertation tries to study the rural inhabitable environment in terms of the human-environment relationship dynamics according to the human geography, the basic logic clue of which is " rural human-environment relationship—rural settlement system -- rural inhabitable environment", the paper is constituted by "background and problems", "perspective and framework", "evolution and laws" , " adjustment and optimization" and " problems and development". The concept of the rural settlement system and the principle and means of geography , economics and system science are applied in the paper to explore the ways of the evolution of the rural settlement system so that the paper seek to present the technological support and the policy suggestions for optimization and development of the rural inhabitable environment. There are six parts in the paper:The first part introduces the theories about the rural inhabitable environment and rural settlement system. The rural settlement system is the fundamental unit of the rural inhabitable environment, It is a kind of rural life system, which has definite territory boundary and spatial concepts , also it is a rural human-environment territory system . the physical ecologic base , material infrastructure network and social cultural environment are the three factors of the system , where the material infrastructure network is the most important part and the connection interface of the rural human-environment interaction. The spatial limitation of the system and the certain definition of the system present a practical platform for the optimization of the rural inhabitable environment.The second part is about the characters of the traditional rural settlement system. The traditional rural settlement results from the spatial demand in the micro-scale; the physical environment, the economic level , social cultural background and the political institution might have impacts on the evolution progress in the macro-scale and produce the final spatial situation due to the tradeoff between the four force. Before the modern urbanization in China, the rural settlement experienced the following stage: the traditional hamlet system dominated by social force, the rural fair system dominated by the economic force and the rural production village system dominated by the political force. The third part analyses the influence factors of the current rural settlement system. The external factors include: the emphasis shift of the national work , setting up of the marketing economic system and the modern urbanization, of which the political and institutional shift are the decision factor. The individual sense and economic rationality of the rural residents awaked by the institutional change, the demand of the space and goods from the rural residents evoked by the industrial development in the rural and the rural spatial effect intensified by the modern urbanization are the rural behavioral reactions to the external environment change. So that the main characters of the Chinese rural settlement are the coexisting of the spatial cluster and spatial disperse , the trend would be turned to spatial disperse from the spatial cluster and the rural would present different heterogeneous space.The fourth part studies the constitution of the current rural settlement system . The rural settlement system is both a kind of periphery space and open space during the modern urbanization, there are multilevel changes in the rural settlement, of which are the radical change and weakening of the physical ecologic base , the quick development and networking of the building environment and the uneven change and pluralism of the social cultural environment, the multilevel change make the rural inhabitable value sophisticated. In the perspective of the scientific development concept, modem rural settlement system is a multifunctional space incorporated with living, producing and ecologic aspect, the internal and external forces of the system drive it evolve. Modern urbanization and the marketing economic tend to make the rural space dying out through the system internal force while the external force ( mostly is the national powerful support) might drive it develop a new charming and competitive settlement.The fifth part is about the spatial arrangement of the modern rural settlement. The dynamic spatial structural factors of the Chinese modern rural settlement involve the spatial regression of the rural settlement center, the spatial integration of the rural settlement units and the spatial extend of the rural settlement passage. The paper applies the production market index (PMI) and life market index(LMI) to analyze the change of the rural settlement center, the economic means to describe the spatial change and the complicated ANN-CA model in the land-use system to simulate the spatial arrangement; based on which a spatial game concept model in terms of the individual behavior , the rural public agency and the private agency is put forward, practically the three kinds of spatial pattern and characters of agglomeration, equilibrium and scattering of rural settlement are presented with different characteristics and spatial structure effects in the rural settlement system , the simply calculating way of spatial structure effects of rural settlement is formed and applied to value the former three patterns in the paper.The sixth part gives the suggestion of adjustment and optimization of the rural inhabitable environment. The dynamic inhabitable environment effect of the rural settlement system turns out the rural inhabitant behavior effect and settlement spatial structural effect; according to the developable and organic attribute of the rural inhabitable environment, the rural settlement center is the key factor of the rural settlement system, the settlement spatial structure has the key impact on the change of the rural inhabitant environment; according to the peripheral feature of the modern Chinese rural settlement, national intervention by the economic ways is the dominant force to control and adjust the rural settlement system and technically simulated through the restraining variables of the ANN-CA model. Above all, the suggestion system includes the spatial political policy to ensure the inhabitable supplying, the spatial economic policy to impel the inhabitable demand and the spatial behavioral policy to lead the inhabitable activity.Above all, the writer is trying to work on the following three aspects: firstly, in terms of the research aims, setting up the leading role of the ideas of the human-environment relationship in the research work of settlement environment and trying to constitute the concept system of the rural inhabitable system and the analysis framework of the settlement environment; secondly, respect to the research contents, exploring the general laws and modem characteristics of Chinese rural inhabitable system to put forward the theoretic and informational base for the optimizing the rural settlement environment; thirdly, making use of the methods of the modern economics and complicated system science applied in the geographical research to uncover the spatial features of the rural inhabitable system.
