Based On Gis And Rs In Urban Fringe Land Use Structure Optimization Study

As a special region, the urban fringe plays a very important role in the city's development process. It is the ligament which contact the city zone with the suburb. As well as, it is the spare space which the city extends increasingly for producing and living. The land use structure of the urban fringe is a strong influence on city, the peripheral region residents' life style, the flow of the main economy factor, the environment pollution. Finding out the changing situation of urban fringe's land use timely and actualizing the urban planning will be beneficial to the sustainable development realizing and constructing the harmonious society. Taking the urban fringe of Jinan city as a case, land use change in the urban fringes is studied by GIS technologies which is analyzed by mathematical model. And then study the measure of optimizing the land use of the urban fringe. The article can be divided into seven parts as followings:The first part gives an introduction. This part expatiate the conception of the urban fringe, the significance, the trends of the research overseas and interiorly. And then, the part briefly states the way of composing, the research frame.The second part is about status of the region nowadays. Spreading from the components of the urban fringe, summarizing the methods of the grand old man, demarcate the scope of the urban fringe of Jinan. And analyze the styles of land use of studied area.The third part, the function of the key city radiation can lead the urban fringe change form time to time and space to space. Analyzing the data which is interpreted form two different time images, obtain the time and space evolutive data of the styles of land use in the studied area by the GIS software. And analyze the data simply.At 4th part: analyze the driving forces of land use change of the urban fringe of Jinan. According to the third part, the evolution of the land use is very complicated, the evolution is not any simple superposition based on some single urbanization. The effect factor has a lot of aspects which is social or natural or blend. Based on the field survey, the main factor is found out, and then gained the main factor which effect the style of land use of Jinan urban fringe each period by simulating.The 5th part: forecast the structure of land use of Jinan urban fringe by the model of Markov, and analyze the forecasted data. Then, evaluate the rationality based on the analysis, and put forward the countermeasure.Epilogue: as the economy developing, the integrative situation will appear. Finger out the contradiction in the development process, and put forward the correspond measures.
