Burdwan City experienced an important urbanization trend inducing dramatic land use/land cover (LULC) changes over the past 28 years. However, their effects on ecosystem services value (ESV) remain unknown. The prime objective of this study is to analyze the spatial heterogeneity of ESV in the Burdwan Planning Area (BPA) from 1990 to 2018. Ecosystem service value (ESV) was estimated using the benefits transfer method, and the contribution of LULC was also computed using contribution rate (CR). The dynamics of LULC were also calculated from the change intensity index and single LULC dynamics. The sensitivity of ESVs to LULC using an elasticity indicator between 1990 and 2018 was performed. The results showed that during the entire study period, built-up are and open lands or sand bars increased 362.34% and 42.40%; water bodies, vegetation, and agricultural lands decreased by 33.24%, 7.20%, and 13.66%, respectively, from 1990 to 2018. In case of ESV, total ESVs were US $95.26 (1990), US $95.85 (2000), US $95.42 (2010), and US $91.38 (2018) million. There was a reduction of the total ESV of US $3.88 million between 1990 and 2018. A substantial spatial heterogeneity of ESV between rural and urban landscapes was reported due to variations of ecological landscapes. The main driver of ESs value loss was a rapid conversion of natural land cover (vegetation, water bodies) into semi-natural or artificial landscapes, i.e., urban settlement. Being a planning region, assessing the impact of LULC dynamics on the ESVs is necessary for sustainable urban development and effective urban environmental management.
在过去28年里，布尔杜万市经历了重要的城市化趋势，引发了剧烈的土地利用/土地覆盖（LULC）变化。然而，这些变化对生态系统服务价值（ESV）的影响仍不明确。本研究的主要目的是分析1990年至2018年布尔杜万规划区（BPA）生态系统服务价值的空间异质性。采用效益转移法估算生态系统服务价值（ESV），并利用贡献率（CR）计算土地利用/土地覆盖变化的贡献率。还根据变化强度指数和单一土地利用/土地覆盖动态计算了土地利用/土地覆盖的动态变化。利用弹性指标对1990年至2018年生态系统服务价值对土地利用/土地覆盖的敏感性进行了分析。结果表明，在整个研究期间，建成区和开阔地或沙洲分别增加了362.34%和42.40%；从1990年到2018年，水体、植被和农业用地分别减少了33.24%、7.20%和13.66%。就生态系统服务价值而言，1990年、2000年、2010年和2018年的总生态系统服务价值分别为9526万美元、9585万美元、9542万美元和9138万美元。1990年至2018年期间，总生态系统服务价值减少了388万美元。由于生态景观的差异，农村和城市景观之间的生态系统服务价值存在显著的空间异质性。生态系统服务价值损失的主要驱动因素是自然土地覆盖（植被、水体）迅速转变为半自然或人工景观，即城市聚落。作为一个规划区域，评估土地利用/土地覆盖动态对生态系统服务价值的影响对于可持续城市发展和有效的城市环境管理是必要的。
