生态系统服务 (ES) 反映了人们从自然生态系统中获得的直接和间接利益，它们在支持和维持人类生存和福祉方面发挥着根本性作用。然而，国家层面的生态系统服务价值（ESV）长期评估很少。因此，根据 Xie 等（2017）的静态 ES 等值系数表，我们选取了净初级生产力、降水量、生物迁移阻力、水土流失和道路密度 5 个变量来调整 4 个一级类别（包括供给服务、调节服务、支持服务和文化服务）和 11 个二级类别的 ES 系数。根据 2000 年不变价格，我们计算了 341 个地级市 2000 年至 2020 年的生态系统服务总价值（ESSV）和人均生态系统服务价值（ESSP）。数据集以 .shp 和 .xls 格式存储，大小为 30.4 MB。该数据库可为生态功能区规划、自然资产核算和生态补偿政策提供支持。该数据库还可用于其他研究。
Ecosystem services (ES) reflect the direct and indirect benefits people obtain from natural ecosystems, and they have a fundamental role in supporting and sustaining human survival and wellbeing. However, there are few long-term assessments of the ES value (ESV) at the national level. Therefore, based on the static ES equivalence factor table from Xie et al (2017), we selected five variables of net primary productivity, precipitation, biological migration resistance, soil erosion, and road density to adjust the ES coefficients of 4 primary categories (including supply service, regulation service, supporting service, and cultural service) and 11 secondary categories. Based on constant 2000 prices, we calculated the total ecosystem services value (ESSV) and per capita ecosystem services value (ESSP) in 341 prefectural-level cities from 2000 to 2020. The unit is 10,000 yuan.The dataset is stored in .shp and .xls formats, and the size is 30.4 MB. This database could support ecological functional zone planning, natural assets accounting, and ecological compensation policies. It could also be used for other studies.
