Intense human activities have altered the land use/land cover (LULC) patterns of lake basins, posing a major challenge to ecosystem sustainability. However, the impacts of land use/cover changes (LUCCs) on ecosystem service value (ESV) of lake basins remain unclear. Here, we investigated ESV of the Baiyangdian (BYD) region from 1980 to 2020 based on value equivalent method, assessed spatial differences of ESVs using hot/cold-spot mapping method, and explored the impact of LUCCs on ESVs in combination with elasticity coefficients. The results showed that (1) the study area was dominated by marsh (50.53 %), water bodies (21.84 %) and cropland (20.28 %) in 2020. Marsh, forestland and grassland significantly decreased from 1980 to 2010, and cropland rapidly rose reaching a peak. Marsh, grassland and water bodies increased during 2010–2020, while cropland decreased. (2) Total ESV was 3469.14 million yuan in 2020, a decrease of 5.77 % compared to 1980 (3681.41 million yuan), mainly due to the decrease in marsh area. (3) ESV hot spots were mainly distributed in the middle part of the region, consistent with water bodies, and ESV cold spots were mainly distributed on the edges of the region, consistent with cropland. The spatial distribution of ESVs varied widely, with an increasing trend. (4) The elasticity coefficients of ESVs to LULC were all greater than 1, indicating that ESVs responded significantly to LUCCs. Overall, there was a strong temporal and spatial correlation between LULC and ESV. This study will provide valuable references for optimizing land use policies and ecological restoration plans and promoting the improvement of ESVs in shallow lakes.

强烈的人类活动改变了湖盆的土地利用/土地覆盖（LULC）模式，对生态系统的可持续性构成了重大挑战。然而，土地利用/覆盖变化（LUCC）对湖盆生态系统服务价值（ESV）的影响仍不清楚。本文基于价值当量法调查了白洋淀地区1980—2020年的ESV，利用热点/冷点映射方法评估了ESV的空间差异，并结合弹性系数探讨了LUCC对ESV的影响。结果表明：（1）2020年研究区以沼泽（50.53%）、水体（21.84%）和耕地（20.28%）为主。1980-2010年沼泽、林地和草地显着减少，耕地迅速上升达到顶峰。2010-2020年期间，沼泽、草地和水体增加，而耕地减少。（2）2020年ESV总额为346914万元，比1980年（368141万元）下降5.77%，主要是沼泽面积减少所致。（3）ESV热点主要分布在区域中部，与水体一致；ESV冷点主要分布在区域边缘，与农田一致。ESV的空间分布差异较大，且呈增加趋势。(4)ESV对LUCC的弹性系数均大于1，表明ESV对LUCC响应显着。总体而言，LULC 和 ESV 之间存在很强的时间和空间相关性。本研究将为优化土地利用政策和生态修复规划、促进浅水湖泊ESV的改善提供有价值的参考。
