As a sub-ecosystem of city ecosystem,urban vegetation is the principal natural factor of the city and it can adjust the environment of the city.The investigation of traditional urban greening mainly by combining artificial investigation with statistic method,needs a great amount of people and money,and data accuracy and timeliness can’t satisfy city development.But by combining high resolution remote sensing data with GIS method,we can extract urban greening data and precisely count its spatial distribution.The paper combines remote sensing data and takes Xiamen city as an example to extract urban vegetation feature data and make a relative analysis.The study showed that urban vegetation has lower diversity index,which only reaches 1.14 in Xiamen.The whole vegetation landscape doesn’t has appropriate distribution pattern with 0.65 of dominance and 0.41 of evenness,there is a phenomena that less vegetation landscape controls the whole greening pattern.Based on the study,the advice was brought forward for vegetation plan in Xiamen.
