| The spatial accessibility is one of the internal driving force of the spatial structure evolution and regional economic development, but also is one of effective elements of evaluate the development opportunity make and the market control ability. And it's an effective indicator of transport network measure also. The spatial accessibility means the convenience level from one specific location to another function place by a specific transport system. It reflect the inter-regional opportunities and potential of the social economy and technical exchange. Regional development depends on the transport network construction to a great extent within urbanization and industrialization. The spatial accessibility research has practical significance to regional transport system improvement, carry capability advance and regional competitiveness enhance.As the main functional areas layout implementing, regional development is being enhanced continuously. For researching the influence of the spatial accessibility to regional economic development better, this paper analyses different characteristics about the spatial regional development, researches relation between tourism economy and accessibility, and proposes the countermeasure of development of tourism economy in the backward areas basing on China coordinating development for provide theoretical instructions and bases of decision-making in narrowing the gap between the east and the west, which is in the perspective of tourism development and against the background of nine node cities of Guizhou province.The paper consists of five chapters:Chapter 1 General Introduction. Analyses the background of selected topic and the meanings of research. Defines the related conception basing on the domestic and foreign scholars' studying extracting. Proposes the research thinking and methods with regional fact. Chapter 2 The review of related spatial theories. Defines the conception of accessibility logically as analyzing these theories. Looks back the process of research methods comprehensively. Introduce the significance of the weighted average model of the transport costs to the research of regional development.Chapter 3 Setting, estimating and analyzing of the Guizhou spatial accessibility index. Sets and estimates the spatial accessibility index of nine node cities, analyses the results Combining ArcGIS9.2,by the accessibility related methods with the regional background of Guizhou tourism economy development.Chapter 4 The countermeasures and the proposals about Guizhou tourism economy development. Proposes the countermeasures about tourism economy development of backward areas basing on analyzing the effect of spatial accessibility index to regional development with regional province situation.Chapter 5 Conclusion and prospect. Summarizes the conclusion and the key viewpoint of this paper and prospects the route of the regional development enhancement and the issues will need to be further study. |
