Urban agglomeration is the key area to realizing regional sustainable development. Timely and accurate assessment of its ESV spatial transfer can provide a scientific basis for intercity environmental cooperation to solve transboundary environmental problems. The ESV and its spatial transfer characteristics in the Central Plains Urban Agglomeration in 2000 and 2018 were quantified by introducing the breaking point model. The findings were as follows: Firstly, taking the central city of Zhengzhou as the transferred-in area, ESV spatial transfer distributions and changes presented a trend of hinterland > metropolitan area. Secondly, the ESV spatial transfer intensity from the metropolitan area to the central city presented an increase trend, with an increase of RMB 498,400-1,053,000/km, and the ESV spatial transfer intensity from the hinterland to the central city presented a decrease trend, with a decrease of RMB 15,200-814,000/km in contrast. Thirdly, a total of RMB 294.763-331.471 billion worth of ESV has been transferred, and only that worth RMB 0.534-1.716 billion reached the central city, accounting for 0.181-0.518% of the total ESV transferred and 2.760-17.482% of the central city's ESV. Fourthly, the ESV spatial transfer radius of each city was 25.47-214.17 km, but the ESV spatial transfer range of a few cities could reach the central city. Lastly, there was inefficiency in the ESV spatial transfer only in the natural driving spatial transfer pattern due to the spatial heterogeneity of ESV distribution, and there was potential for strengthening the ecological interactions based on space guidance provided by ESV spatial transfer.
城市群是实现区域可持续发展的关键区域。及时准确地评估其生态系统服务价值（ESV）的空间转移，可以为城市间环境合作提供科学依据，以解决跨境环境问题。本研究通过引入断裂点模型，量化了 2000 年和 2018 年中原城市群的 ESV 及其空间转移特征。结果表明：（1）以中心城市郑州为转入区，ESV 空间转移分布和变化呈现出内陆地区>大都市区的趋势；（2）大都市区向中心城市的 ESV 空间转移强度呈增加趋势，增加了 498400-1053000 元/km，内陆地区向中心城市的 ESV 空间转移强度呈减少趋势，减少了 15200-814000 元/km；（3）共转移 ESV 价值 294.763-331.471 亿元，仅有 0.534-1.716 亿元的 ESV 价值到达中心城市，占转移 ESV 总价值的 0.181-0.518%，占中心城市 ESV 的 2.760-17.482%；（4）各城市的 ESV 空间转移半径为 25.47-214.17km，但部分城市的 ESV 空间转移范围可达中心城市；（5）仅在自然驱动的空间转移模式下，ESV 空间转移效率低下，这主要是由于 ESV 分布的空间异质性，在 ESV 空间转移的空间引导下，加强生态相互作用具有潜力。
