Ecosystem services are the bridge between ecosystem functions and human welfare. Climate regulation service (CRS) has an extremely important role in ecosystem services. It is important to conduct a comprehensive assessment based on the whole process of CRS occurrence for scientific assessment of ecosystem services. With Fuzhou City as a case, we carried out the assessment of CRS at the local and municipal scales, and analyzed the spatial and temporal variations of CRS at the administrative unit and land use and land cover scales. The results showed that the aggregated physical capacity of CRS in Fuzhou City was 4.01×10 MJ (monetary value 613.944 billion yuan, GDP 561.808 billion yuan) and 4.66×10 MJ (monetary value 714.002 billion yuan, GDP 785.681 billion yuan) in 2015 and 2018, respectively, and that the monetary value of CRS was roughly equivalent to the GDP of that year. The main land use/cover (LULC) type was woodland, cultivated land, and water area, which accounted for 57%, 15%, and 9% of Fuzhou's land area, respectively. Water area contributed the most to Fuzhou's CRS, with a contribution of over 60% in 2018, higher than woodland (12%), and cultivated land (13%). The CRS was lower in built-up areas and eastern farming areas. Between 2015 and 2018, the area of LULC change in Fuzhou was 1805.5 km. The largest changes were cultivated land and wood land. The main land use transfer direction was between cultivated land and woodland, woodland and garden land, cultivated land and residential and industrial and mining land. The aggregated physical capacity of CRS changed by 6.74×10 MJ, while the corresponding monetary value of 103.58 billion yuan. The CRS changes were concentrated in the central and western regions such as Minhou, Minqing, and Yongtai, and the western mountainous regions such as Luoyuan and Fuqing. The most drastic change of CRS was found in water area. The conversion of water areas produced extremely strong changes in CRS, much stronger than the effects of conversion of other LULC types.
生态系统服务是生态系统功能与人类福祉之间的桥梁。气候调节服务（CRS）在生态系统服务中具有极其重要的作用。基于CRS发生的全过程进行综合评估对于科学评估生态系统服务至关重要。以福州市为例，我们在地方和市级尺度上开展了CRS评估，并分析了行政单元以及土地利用和土地覆盖尺度上CRS的时空变化。结果表明，福州市CRS的综合物理容量在2015年和2018年分别为4.01×10⁶兆焦（货币价值6139.44亿元，国内生产总值5618.08亿元）和4.66×10⁶兆焦（货币价值7140.02亿元，国内生产总值7856.81亿元），且CRS的货币价值大致相当于当年的国内生产总值。主要土地利用/覆盖（LULC）类型为林地、耕地和水域，分别占福州市土地面积的57%、15%和9%。水域对福州市CRS的贡献最大，2018年贡献超过60%，高于林地（12%）和耕地（13%）。建成区和东部农业区的CRS较低。2015年至2018年期间，福州市LULC变化面积为1805.5平方千米。最大的变化发生在耕地和林地。主要土地利用转移方向是耕地与林地、林地与园地、耕地与居住及工矿用地之间。CRS的综合物理容量变化了6.74×10⁶兆焦，相应货币价值为1035.8亿元。CRS变化集中在闽侯、闽清、永泰等中西部地区以及罗源、福清等西部山区。CRS变化最剧烈的是水域。水域的转变对CRS产生了极其强烈的变化，远强于其他LULC类型转变的影响。
