摘　　要：选取植被固碳、土壤保持和水源涵养3项指标,运用生态系统服务综合评估模型(InVEST)对扬州市中心城区公园建设前(2010年)和建设后(2018年)生态系统服务的物质量进行估算,为评估公园建设后的生态效益提供新视角。结果表明:①3项生态系统服务物质量的高值区出现在市区西北部,如宋夹城体育休闲公园、蜀冈西峰生态公园等;②不同生态系统服务的物质量由大到小依次为市级综合公园、区级综合公园、社区公园、口袋公园;③公园建设后各项生态系统服务的物质量较建设前明显增加,特别是市级综合公园的增幅最大。评估结果为今后扬州市中心城区公园城市建设与管理提供重要的科学依据。Three indicators, including vegetation carbon storage, soil retention and water retention, were chosen to evaluate ecosystem services of parks in central areas of Yangzhou using an Integrated Valuation of Environmental Services and Tradeoffs(InVEST) before and after the park construction in the year of 2010 and 2018, which provided a new perspective for ecological benefit assessment after the park construction. The results showed that: ① The higher values of three types of ecosystem services appeared in northwestern areas, such as the Songjiacheng Sports & Leisure Park and Shugangxifeng Ecological Park. ② The values of different types of ecosystem services were as follows: municipal parks>district-level parks>community parks>pocket parks. ③ The values of each type of ecosystem services obviously increased after the park construction, especially in the municipal parks. The evaluation results will provide an important scientific basis for future construction and management of the park city in Yangzhou.
