Land use and land cover in cities experience complicated changes in response to rapid urbanization, requiring significant impact on ecosystem service value. However, traditional valuation methods tend to ignore artificial ecosystem. This study develops a novel Unit Value (UV) method to evaluate urban ecosystem service values with both natural and artificial ecosystems considered comprehensively. This method is used to reveal the spatial-temporal evolution of ESV in Wuhan from 1996 to 2018. Additionally, Pearson's correlation between ESVs and driving factors is studied by using a multiple regression model. The results show that: (1) Ecosystem service values are observed to increase by 20.94% because of land use and land cover increases in woodland ((32.21%) and man-made wetland (61.73%) in 1996-2018, respectively. (2) ESVs declined in central districts and increased in suburban districts, with a clear imbalance between "high central areas" and "low suburban areas". (3) Human activities play a more important role in urban ecosystem compared to natural environmental factors, especially agriculture, per capita GDP, and population. This study provides a distinctive method for the spatiotemporal evaluation of urban ecosystem service values, establishing an insightful basis for urban sustainable development.
城市中的土地利用和土地覆盖因快速城市化而经历复杂变化，这对生态系统服务价值产生重大影响。然而，传统估值方法往往忽视人工生态系统。本研究开发了一种新颖的单位价值（UV）方法，以综合考虑自然和人工生态系统来评估城市生态系统服务价值。该方法用于揭示1996年至2018年武汉市生态系统服务价值（ESV）的时空演变。此外，利用多元回归模型研究了ESV与驱动因素之间的皮尔逊相关性。结果表明：（1）1996 - 2018年期间，由于林地（32.21%）和人工湿地（61.73%）的土地利用和土地覆盖增加，生态系统服务价值增长了20.94%。（2）中心城区的ESV下降，郊区的ESV上升，“高中心区”与“低郊区”之间存在明显失衡。（3）与自然环境因素相比，人类活动在城市生态系统中发挥着更重要的作用，尤其是农业、人均GDP和人口。本研究为城市生态系统服务价值的时空评估提供了一种独特方法，为城市可持续发展奠定了有见地的基础。
