摘要:地图是直观展示生态系统服务空间分布格局的手段，是确定重要生态保护目标和区域的主要方法。结合制图学理论方法及国家、行业相关制图规范，探讨生态系统服务分布图编制的目标、原则、流程和制图方法。以编制北京市延庆区1 ： 25万土壤保持服务分布图为例，分析了地理基础确定、地理要素取舍以及土壤保持服务分级等关键制图方法，提出了土壤保持服务分布图的编制规范。研究结果表明，编制的图件能够详尽的展示土壤保持服务的分布特征，精细的反映生态系统服务与自然、人文要素的关系。通过详实的图面信息可进一步判别土壤保持服务分布重要区域，这将为区域生态环境保护规划提供重要技术手段。



Abstract:Mapping is one best mean to visually display spatial patterns of ecosystem services, and has become an important method for determining significant targets and regions of ecological protection. This paper analyzes the objectives, principles, processes and methods for mapping distribution of ecosystem services in terms of cartography theory and related national or industrial standards for mapping. Taking a distribution map of soil retention service at 1:250000 scale in Yanqing District as a case study, the key mapping issues such as determination of geographic bases of the map, selection of natural and social geographic elements, and classification of soil conservation capacity are analyzed. Further, the specification of soil retention distribution maps at county scale is proposed. The results show that the map of soil retention service complied with the above method displays the distribution patterns of soil retention service, and reflects the spatial connection between soil retention service and geographical elements. Also, it helps to identify ecologically important areas with detailed and truthful information on the map. Thus, our study can provide important technical means for locally ecological environmental protection planning.
