| 研究生态系统服务时空变化及其权衡关系对推动生态系统可持续管理及平衡经济发展与生态文明建设具有重要意义。本研究综合土地利用、高程及降水等多源数据，采用InVEST模型及相关性分析等方法，分析了2000—2020年长三角一体化示范区土地利用变化以及生态系统服务(包括碳储存、水质净化及生境质量)的时空分布特征及其权衡/协同关系。结果表明：(1)研究区土地利用以耕地、建设用地和水体为主，占总面积的98%;2000—2020年，土地利用变化主要由耕地向建设用地的转变，导致耕地面积减少437 km2。(2)2000—2020年，示范区水质净化、碳储存及生境质量均呈下降趋势。(3)在空间分布上，碳储存量逐渐由西北低东南高转变为相对均匀分布，水质净化能力在建设用地和耕地与水域交界处较低，生境质量逐渐由南低北高转变为相对均匀分布。(4)示范区生境质量与碳储存呈现权衡关系且权衡强度逐渐减弱，生境质量与水质净化之间为协同关系，碳储存与水质净化之间为权衡关系。研究结果可为长三角一体化示范区高质量发展提供决策依据。 |

| Clarifying the functions of ecosystem services and their trade-offs is crucial for promoting sustainable ecosystem management，balancing economic development，and constructing ecological civilization.This study integrates multi-source data，including land use，elevation，and precipitation，employing methods like the InVEST model and correlation analysis.It analyzes the spatiotemporal characteristics of land use changes and ecosystem services (including carbon storage，water purification，and habitat quality) in the Yangtze River Delta Integrated Demo Zone from 2000 to 2020，as well as their trade-offs or synergies.The results show：(1) Land use in the study area is dominated by cultivated land，construction land，and water bodies，which account for 98% of the total area.From 2000 to 2020，there was a shift from cultivated land to construction land，leading to a decrease in cultivated land area by 437 km2.(2) From 2000 to 2020，water purification，carbon storage，and habitat quality in the demo zone exhibited a declining trend.(3) Spatially，carbon storage gradually transitioned from a distribution with low carbon storage in the northwest and high carbon storage in the southeast to a relatively uniform distribution;water purification capacity was lower at the interface of built-up land and cropland with water bodies，and habitat quality transitioned from a distribution with low habitat quality in the south and high habitat quality in the north to a relatively uniform distribution.(4) There is a trade-off relationship between habitat quality and carbon storage，with the trade-off intensity gradually weakening.There is a synergistic relationship between habitat quality and water purification，while a trade-off relationship exists between carbon storage and water purification.This study results can provide decision-making support for the high-quality development of the Yangtze River Delta Integrated Demo Zone. |
