摘　　要：近年来,生态系统服务价值已成为环境生态学和生态经济学的热点问题。植被生态服务功能越来越受到城市规划及园林景观规划学者的关注（杨小波等,2002;任志远等,2003）。林地是植被最主要的组成形态,其功能与价值正在被深入挖掘。This study is designed to evaluate the ecological value of forests in purifying the air,decreasing carbon dioxide and releasing oxygen in Wutong Mountain of Shenzhen,China in 2005. The aerial photography of 0. 3 m resolution and the data of eight forest quadrats of Shenzhen Wutong Mountain in 2005 were collected and analyzed by using ArcGIS software and Citygreen model. Based on some newly established models and optimized parameters,we estimated that the ecological value of Wutong Mountain＇s forests in terms of fixing carbon,releasing oxygen,and purifying the air in 2005 was worth 155. 60 million RMB. The predictive carbon fixation and oxygen release values of Wutong Mountain forest would be 178. 35,197. 40,215. 97,235. 01,and 255. 91 million RMB respectively in 2015,2025,2035,2045 and 2055. The estimated ecological service value in reducing pollution and purifying the air was 4. 52 million RMB in 2005. The accordingly predictive values would be 5. 176 0,5. 727 7,6. 271 2,6. 793 1 and 7. 4259 million RMB respectively in 2015,2025,2035,2045 and 2055. These results show there are huge ecological service values of forests in fixing carbon,releasing oxygen,reducing pollution and purifying the air. The difference between the varied growth rates of trees and the growth rate of ecological benefits in different years depends upon the constraint and influence of the growth patterns among different kinds of trees.
