Abstract
Combining the current urgent demand of urban earthquake disaster reduction tasks with the refuge value of green park, this paper establishes the index system of suitability evaluation of urban green park to earthquake disaster prevention and refuge based on 3 S technology. Considering the concept of earthquake disaster reduction and refuge, the index system mainly included three senior grade indexes such as security, transport accessibility and validity and eight junior grade indexes. A synthetical evaluation system (SES) with fuzzy optimization theory, entropy and comprehensive index model as core technique was built taking RS (remote sensing) and GPS (global positioning system) as data acquiring method and GIS (geographic information system) as data analyzing platform. Huangpu District of Shanghai Municipality was selected as a case study by using SES. The results show that this system can provide an auxiliary solution to establishing construction project about the urban green parks for the earthquake disaster prevention and refuge, optimizing the location of emergency refugium and examining benefit of exsisting refugiums.
