Ecosystem services (ESs) play an important supporting role in the development of human society and the economy. Despite the increasing number of ESs quantitative evaluation studies that have been conducted at different scales, the assessment of ESs flows between different administrative regions, which provides valuable implications for ecological protection and compensation, has drawn little attention. The aim of this study is to fill in this gap by providing a comprehensive ES interregional flow analysis method that evaluates ecosystem service values (ESVs) and quantifies the interregional flows in the Yangtze River Delta (YRD), which is home to one of the largest urban agglomerations in China. The results showed that the total ESV of the YRD increased from 2.02E+12 Chinese Yuan (CNY) in 2000 to 2.33E+12 CNY in 2019, a 15.23% increase rate. All types of ESVs displayed an increasing trend during the 20 years. According to the analysis of interregional ES flows in the YRD, Zhejiang province played a crucial role as a service providing area (SPA) for the spatial value transfer at the provincial level in both 2000 and 2019. Anhui province was the largest service benefitting area (SBA) of water conservation and CSOP, while Jiangsu province was the largest SBA of soil retention. The recognition of interregional ESV flows can provide valuable information for environmental planning and management to help improve China's ecological compensation policies for different administrative divisions.
生态系统服务（ESs）在人类社会和经济发展中起着重要的支撑作用。尽管在不同尺度上进行了越来越多的 ES 定量评价研究，但对不同行政区之间的 ES 流动的评估，这对生态保护和补偿具有重要意义，但却很少受到关注。本研究旨在通过提供一种全面的 ES 区域间流动分析方法来填补这一空白，该方法评估生态系统服务价值（ESV）并量化中国最大的城市群之一——长江三角洲（YRD）的区域间流动。结果表明，长三角的总 ESV 从 2000 年的 2.02E+12 人民币（CNY）增加到 2019 年的 2.33E+12 CNY，增长率为 15.23%。在这 20 年中，所有类型的 ESV 都呈上升趋势。根据对长三角区域间 ES 流动的分析，浙江省在 2000 年和 2019 年的省级层面空间价值转移中作为服务提供区（SPA）发挥了关键作用。安徽省是水资源保护和 CSOP 的最大受益区（SBA），而江苏省是土壤保持的最大 SBA。对区域间 ESV 流动的认识可以为环境规划和管理提供有价值的信息，有助于改善中国对不同行政区的生态补偿政策。
