Therefore, research on the open space of urban geography and optimize the urban space, from the Angle of regional integration and geography to rational layout, the empirical research has an absolute advantage, and can make more intuitive and prospective study.This article comes from the National Natural Science Foundation-the research on spatial pattern and process of urbanization based on the ESDA-GIS in Yanji area(40861007), based on the frontier minority areas of small and medium-sized cities-yanji city, used the advanced technology of GIS and RS, combining urban geography, landscape ecology theory and quantitative analysis, discusses the changes of landscape structure and spatial distribution characteristics and open space of yanji, accessibility and related on the basis of the research of yanji pertinently put forward the countermeasures to optimize open space.This paper has five chapters. The first chapter is introduction. Concludes background and significance, and based on the related studies systematically, analyzed the open space of the relevant research progress, and puts forward the ideas and research framework. The second chapter for urban open space of relevant basic research. Analyses urban open space on the connotation and function, and the construction of urban space due to the outside, open space is different understanding; In the research on the theory of open space in urban geography and landscape ecology is a combination of new enlightenment. The third chapter of open space for research in yanji city. Firstly, in technology support of GIS and RS, based on the analysis on landscape ecology landscape pattern of yanji, quantitative analysis of urban open space pattern change and spatial distribution characteristics, and then based on the related theories of accessibility, analyzed the buffer analysis of yanji city open space accessibility. Chapter four is optimization countermeasures on open space of yanji city. Based on the analysis results of the third chapter, pertinently put forward the open space of the optimization countermeasures and Suggestions. The fifth chapter is closing. This paper summarized the main conclusion, and puts forward the problems and future needs further discussion.At present, Open space planning and construction in China has becoming an important subject of many cities. Therefore, this research can provide scientific and valuable reference and basis for opening space of reasonable planning and construction to yanji city.
