| 中文摘要: |
| 以成渝地区双城经济圈为研究区，基于2010年、2016年和2022年3期土地利用类型数据，采用当量因子法对研究区进行县域土地生态系统服务价值测算，划分生态补偿优先级，估算生态补偿额度。结果表明：研究区生态系统服务价值呈现先上升后下降的趋势，由2010年的1 89321亿元上升至2022年的1 94340亿元，整体呈上升趋势；生态补偿优先级指数高值区主要分布在研究区西南部、南部和部分东部的边缘县（市、区），生态补偿额度最高值分布在研究区西南部，较高值分布在研究区西南部、南部、东南部边缘各县（市、区），生态补偿额度低值区或较低值区分布在成都市和重庆市中心城区及周围县（市、区）。 |

| Taking Chengdu Chongqing economic circle as the research area， this study calculated the land ecosystem service value（ESV） at the county level in the study area， classified priorities for ecological compensation and estimated the amount of ecological compensation by the equivalent factor method， based on three periods of land use type data in 2010， 2016， and 2022. The results showed that the ESV in the study area exhibited a trend of first rising and then falling， increasing from 189.321 billion yuan in 2010 to 194.340 billion yuan in 2022， showing an overall upward trend. Areas with a high priority index of ecological compensation were mainlydistributed in the southwestern， southern，and some eastern border counties（cities， districts） of the study area. The highest value of ecological compensation amount was in the southwest of the study area， the relatively high values were distributed in the southwestern， southern and southeastern border counties（cities， districts） of the study area， and the low or relatively low values were in the central urban areas of Chengdu and Chongqing and their surrounding counties（cities， districts）. |
