设计了一种基于GIS的方法，在空间上估算生态系统服务的直接使用价值，并绘制结果，用于县级案例研究。该方法强调使用地理信息系统收集数据，进行空间分析，并绘制生态系统服务的经济价值。基于地理信息系统的技术框架说明了农产品、森林产品和旅游服务空间估价的三个关键步骤。我们将这种方法应用于天台县（1423.8 km（2））在中国东南部的浙江省。案例地区的自然产品和旅游服务的选定组成部分被绘制成地理信息系统的数据层，每一层包含每25米的货币价值。cell. 2005年生态系统服务直接使用价值约为5.38亿元人民币，其中农产品、林产品和旅游服务分别占65%、30%和5%。根据从案例研究中了解到的直接使用服务的异质性，确定了管理目的的关键领域。空间上明确的措施提供了一种机制，将空间背景纳入生态系统服务评价。在此基础上，通过实例分析，提出了基于GIS的区域资源保护和生态环境管理的建议。预计这项工作将突出研究途径，以推进生态系统服务框架，作为区域生态系统管理的业务基础。(C)2008 Elsevier B.V.保留所有权利。
A GIS-based approach was designed to spatially estimate direct use value of ecosystem services and to map results for a case study at county scale. The approach highlights the use of GIS to collect data, perform spatial analysis, and map economic values of ecosystem services. Three key steps of spatial valuation for agricultural products, forest products, and tourism services were illustrated in the GIS-based technical framework. We applied this approach to the Tiantai County (1423.8 km(2)) in Zhejiang province of southeast China. Selected components of natural products and tourism services in the case area were mapped as data layers in GIS, with each layer containing monetary values for every 25 m. cell. The total direct use value of ecosystem services was estimated in RMB to be approximately 538 million Yuan in 2005 (Chinese currency, 8.2 Yuan=US$1), of which agricultural products, forest products and tourism services accounted for 65%, 30% and 5%, respectively. The critical areas for management purpose were identified depending on the heterogeneity of direct use services learned from the case study. The spatially explicit measures provide a mechanism for incorporating spatial context into ecosystem services evaluation. Based on the present GIS-based approach and case study, the suggestions and implications for local resources protection and eco-environmental management were extensively discussed. The work was expected to highlight research avenues to advance the ecosystem services framework as an operational basis for regional ecosystem-based management. (C) 2008 Elsevier B.V.
