| Along with the rapid growth of economic development, the human beings have been addressed abundant substance civilization, and on the other hand, series crisis about the population expansion, resource shortage, ecological destruction and environmental pollution have emerged. Therefore, the human beings must change traditional development mode into sustainable development mode. The sustainable development of microcosmic region is the basis of macroscopical sustainable development. From the viewpoint of geography science, the study on the regional systemic sustainable development based on the systemic analysis theory is an innovative and valuable behavior to the field of regional sustainable development research.Based on theoretical deduction, this thesis established an indicators' system and a model as well to assess the regional sustainable development on the county level, and analyzed the structure, function, characters and feedback relation of regional sustainable developmental system by taking Qingyang as a case. Based on the approach of GIS and SD, this thesis respectively analyzed the characters of the temporal and spatial evolvement on the sub-regional sustainable development in Qingyang, and doped out the temporal and spatial evolvement trend as well. In the end, the road to address the sustainable development of Qingyang is designed and proposed. The research includes several aspects as following:1. Analysis on the assessment indicators' system and assessment model. This thesis proposed an indicators' system, which is categorized as meta-data index and secondary index, to assess the regional sustainable development on county level. And then, this thesis established a general assessment model considered the sustainability and co-ordinability to synthetically evaluate the regional development.2. Analysis on the regional sustainable developmental system. The outcome shows that the system contains a series of complicated causality and feedback which is represented as catena closed loops. The loops affect each other result of redirecting the regional sustainable development system. 3. Assessment of the regional sustainable development of Qingyang. The thesis assessed and analyzed the quo state of sub-regional (county level) sustainable development in Qingyang. The outcome shows that the integrated sustainability on the county level is increased gradually, where the driving force for increasing is due to the rapid growing of the society and economy along with the cost of abundant resources consumption and ecosystem degradation.4. Prediction of regional sustainable development of Qingyang. This thesis predicted the evolvement trend of sub-regional sustainable development in Qingyang based on the methodology of SD. The outcome shows that the traditional economic development mode is not sustainable. Under the traditional economic development, the integrated sustainability of sub-region will decline continually from 2007 to 2020. The decline could be more obvious if the economic growth is more rapid.5. Analysis on the evolvement of spatial structure of regional sustainable development of Qingyang. This thesis analyzed the historical evolvement and trend of spatial structure disciplinarian of regional sustainable development based on the method of Gravity Center Shift. The outcome shows that the spatial distribution is unbalance. The spatial structure is unsteady, and the undulation is obvious. The more rapid growth of economic development, the undulation is more obvious, and the regional sustainable development system is more unsteady.6. Analysis on the developmental path to meet the regional sustainable development. From the perspective of ecological economics, this thesis proposed a suitable path used for Qingyang to meet the sustainable development, which embodies the conception of ecological economics. It is considered that the suitable path includes ecological industry, ecological agriculture, ecological service industry and ecological consumption.In conclusion, on the one hand, this thesis is of important theoretical significance, which is expected to enrich and develop the theory on regional sustainable development, and to provide new idea and method as well for the research on regional sustainable development. On the other hand, this thesis has prominent practical significance, which could provide scientific foundation for the local government to make the developmental polices which is propitious to achieve the microcosmic regional sustainable development, and to meet the whole macroscopically sustainable development of Qingyang. |
