ABSTRACT

Context: Without clear understanding of the units used for ecosystem service (ES) mapping, ES assessment accuracy and the practical application of ES knowledge will be hampered. Method: We systematically reviewed 106 studies over the past 11 years to explore the type, characteristic pattern and deficiencies of mapping units. Result: We proposed that ES mapping units can be categorized into minimal unit for assessing ESs using corresponding indicators and methods, and aggregated unit for analysis and application based on research objectives, and classified the mapping units into five common types. Of the 12 characterizing variables of ES mapping studies, some have been shown to introduce a difference in the selection of mapping units and to exhibit characteristic patterns. We also found that the accuracy of ES assessments based on minimal units was lacking, and aggregated units were insufficient to establish a link between ES knowledge and practice. Conclusion: Herein, we propose possible solutions such as the use of fine spatial resolution grids and the introduction of additional data beyond land cover as supplements to improve the assessment accuracy. To enhance the availability of the results for practice, aggregated units connected with urban planning units should be established at a spatial level suitable for urban management.

摘要

背景：如果没有清楚地了解用于生态系统服务（ES）制图的单位，则ES评估的准确性和ES知识的实际应用将受到阻碍。方法：我们在过去11年中系统地回顾了106项研究，以探讨制图单位的类型，特征模式和缺陷。结果：我们建议，可以使用相应的指标和方法将ES映射单元划分为用于评估ES的最小单元，并根据研究目标将其汇总用于分析和应用，并将映射单元分为五种常见类型。在ES映射研究的12个表征变量中，有些已显示出在映射单元选择上的差异并表现出特征模式。我们还发现，缺乏基于最小单位的ES评估的准确性，并且汇总的单位不足以在ES知识和实践之间建立联系。结论：在此，我们提出可能的解决方案，例如使用精细的空间分辨率网格以及引入土地覆盖范围以外的其他数据作为提高评估准确性的补充。为了提高结果的实用性，应在适合城市管理的空间水平上建立与城市规划单位联系的综合单位。
