Research Of Urban Green Space Accessibility Based On RS And GIS In The Xiamen Island

Urban green space is an essential component of urban landscape. As the main habitat of all propagation living in urban environment, urban green space can improve the conditions of urban environment and maintain the ecological balance of urban ecosystem. Further more, as a space where is full of nature elements, urban green space would also bring many social benefits to the city, such as enhance city influence, providing exercise sites for residents, and improving quality of city life.Nowadays city residents have began to pay more attentions to the quality of the environment where they live. Because of this background, the effects of urban green space have also attracted more notice from the scholar all over the world, aim to design a better urban green system with both higher social and ecological benefits.Through the RS and GIS technologies, we using the Xiamen Landsat TM Image, Xiamen land-use map and Xiamen prospective green space planning map as resource data to build a digital map of Xiamen as analyse platform. Green space accessibility is adopted as main evaluate index, the research estimated the efficiency of green space in current and in future on Xiamen island, and made proposals for the improvement of green space constructions in the area with bad accessibility condition, the opinions for furthur urban green system planning are also concluded at the end according to the characteristic of cost value distribution and ecology landscape principle.The methods used in this research showed a good application potential in many aspects, such as looking for available resources, estimating urban green space conditions, displaying the variation of space distributions visually and so on, thus providing an effective decision support system to green space constructions of Xiamen in the future.
