表1 遥感生物多样性产品的优先排序标准更新(修改自Skidmore等(2021))

Table 1 Updated remote sensing biodiversity product prioritization criteria (revised from Skidmore et al (2021))

序号 Number 优先原则 Prioritization criteria 描述 Description 1 关联性 Relevance 遥感生物多样性产品的使用目的与方法决定了关联性的强弱。主要关注以下方面与遥感生物多样性产品的相关性: (1)管理问题; (2)为CBD目标提供信息; (3)为SDGs提供信息; (4)为生物多样性和生态系统服务政府间科学政策平台(IPBES)的风险评估过程提供数据。It is known who wants the remote sensing biodiversity product, what they will do with it and how it will be used. The remote sensing biodiversity product is relevant: (1) for management questions; (2) to inform the CBD targets; (3) to inform the SDGs; and (4) to provide data for the IPBES risk assessment processes. 2 可行性 Feasibility 可行性这一标准考虑了遥感数据的可用性、获取数据的便利性、遥感在时空尺度的完整性以及数据整合与分析的便利性和经济性。This criterion considers the availability of remote sensing data, the ease of access to such data, the completeness of remote sensing in space and time and the ease and affordability of data integration and analysis. 3 准确性(遥感状态) Accuracy (remote sensing status) 准确性是指衡量某一遥感生物多样性产品观测准确性的标准, 该标准考虑了遥感数据以及获取精准遥感生物多样性产品技术的有效性。A measure of the current activity for the accurate observation of a given remote sensing biodiversity product. This criterion considers the effectiveness of remote sensing data and techniques to achieve an accurate and precise value of the remote sensing-enabled biodiversity product. 4 成熟度(遥感状态) Maturity (remote sensing status) 成熟度这项标准指的是目前遥感生物多样性产品是否成熟且其程度如何, 即有能力生产遥感生物多样性产品的组织/机构是否可以向资助机构提出产品生产建议, 以及该项任务完成的难度如何。Maturity refers to the maturity and status of the current remote sensing biodiversity products. Institutions/organizations with hopes to generate remote sensing biodiversity products can be identified and/or proposed to a funding body. 5 可重复性(新添加) Repeatability (new addition) 可重复性主要描述某一遥感生物多样性产品在未来预期能够按照一定时间分辨率获取的能力, 即评判能否按照预期规律性获取遥感生物多样性产品及该需求的难度。Repeatability mainly describes the ability of a certain remotely sensed biodiversity product to be expected to be accessible at a certain temporal resolution in the future, i.e., it judges whether the remotely sensed biodiversity product can be accessed with the expected regularity and the difficulty of that demand.
