Based on the interpreted and classified remote sensing images of Shenzhen in 1990,1995,2000,and 2005,and the platform of ARCVIEW,with the application of the air purification,carbon fixation and oxygen release modules in the CITYGREEN model,the estimation is made on the ecosystem service function value of greenbelt system in Shenzhen city.The research showed that,in the aspect of air purification,the values of ecosystem services from 1990 to 2005 were $2.0394 million,$3.3258 million,$2.0252 million,and $2.9806 million,respectively.The values of ecology sensitive support functions area which were $0.2148 million,$0.1676 million,$0.2176 million,and $0.1742 million were the highest.As to carbon fixation and oxygen release,the values of ecosystem services for each year were $4469.16 million,$4549.94 million,$4471.35 million,and $4077.7 million respectively.The values of western coast agro-industrial coordination area which were $0.5569 million,$0.9516 million,$0.5352 million,and $0.6905 million were the lowest.The results showed that urban greenbelt system was of great importance in urban ecosystems,with notable ecosystem service function values.The research also showed that,due to the unbalanced urbanization,there was high regional differentiation in all landscape ecological functional areas in Shenzhen City.
