【摘要】 采用遥感驱动山地当量因子法（RS-MEF）评估长汀县生态系统服务价值及水土保持生态资产增值效应。采集2000年和2022年遥感影像、统计数据等，计算标准当量因子、确定当量系数、开展地物分类、进行空间异质性修正，最后计算得到生态系统服务价值。研究结果表明，20多年间长汀生态系统服务价值从2000年的74.64亿元增长至2022年的348.30亿元。其中，水土流失重点治理区生态系统服务价值由2000年的26.79亿元增长为2022年的144.38亿元，增长率高于全县水平，其占全县生态系统服务价值的比重也从2000年的35.89%提升至2022年的41.45%。该结果可为长汀实现生态产品价值转化提供科学依据，对区域绿色可持续发展提供参考。更多还原

【Abstract】 It was evaluated the service value of ecosystem and the value-added effect of soil conservation ecoassets by the adoption of the remote sensing driven mountain equivalent factor method (RS-MEF).Through the remote sensing images and statistical data in 2000 and 2022,it was calculated the standard equivalent factor,determined the equivalent coefficient,classified the land cover,corrected the spatial heterogeneity,and finally calculated the ecosystem service value.The research result shows that within more than 20 years the service value of ecosystem at Changting County was increased from 7,464 million RMB in 2000 to 34,830 million RMB in 2022.Of which,the service value of the ecosystem at the key control area for soil erosion has been increased from 2,679 million RMB in 2000 to 14,438 million RMB in 2022,with the growth rate higher than the county level.The proportion in the total ecosystem service value of the county has also been increased from 35.89% in 2000 to 41.45% in 2022.The result can provide the scientific basis for the realization of eco-products value transformation at Changting County and provide the reference for the regional green sustainable development.Key words:Changting County,service value of the ecosystem,soil erosion control,value added of eco-asset,更多还原
