摘　　要：森林是最重要的陆地生态系统类型之一,在生态文明建设中具有举足轻重的地位,研究独具森林资源优势地区的生态系统生产总值(GEP)变化及其对土地利用变化的响应对促进该类区域可持续发展具有重要意义。本研究以江西省资溪县为研究区,基于生态系统价值核算理论和方法,在调节服务通用指标体系(水源涵养、土壤保持、氧气提供、碳固定、气候调节、洪水调蓄、水质净化、空气净化、物种保育)及文化服务通用指标体系(景观游憩、教育)基础上,增加负氧离子、康养等指标,并引入森林生态系统服务修正系数,构建独具森林资源优势的GEP指标体系和方法,评估了研究区2010、2017和2020年GEP的时空变化特征,采用弹性指数及价值损益分析方法量化了土地利用/土地覆盖变化对GEP的影响。结果表明:2010、2017和2020年资溪县GEP分别为167.88、268.17和384.07亿元。各生态系统GEP占总GEP比例依次为森林>湿地>农田>草地>城镇。研究期间,GEP增加值主要来源于森林生态系统。土地利用变化对GEP产生了重要影响。2010-2020年,研究区土地利用变化总面积为8501.88hm^(2)。各土地利用变化幅度依次为草地(-2811.17hm^(2))>城镇(1428.06hm^(2))>森林(1357.67hm^(2))>湿地(1031.05hm^(2))>农田(-1005.01hm^(2))。各类用地的绝对变化主要发生在2017-2020年。各测算指标对森林生态系统的弹性指数明显高于其他生态系统,说明GEP对林地面积变化的敏感性最高。价值损益分析表明,城市开发在一定程度上降低了GEP,林地、湿地的保护促进了GEP增加。2010-2020年,资溪县土地利用类型之间的转化导致GEP增加18.65亿元,说明资溪县土地利用变化整体上对生态的影响是正向的。研究结果一定程度上体现了资溪县成为国家生态文明建设示范县之后的绿色发展成效,也为研究区今后高质量发展、高水平保护和土地资源可持续开发Forests are one of the most important terrestrial ecosystems and play a crucial role in the construction of ecological civilization. Understanding the changes in gross ecosystem product(GEP) and its response to land use change in areas with unique advantages in forest resources is of great significance for promoting sustainable development. We examined the GEP of Zixi County of Jiangxi Province. Based on the theory and method of ecosystem value accounting, and on the basis of the general indicator system for regulating services(water source conservation, soil conservation, oxygen supply, carbon fixation, climate control, flood regulation, water purification, air cleaning, species conservation) and the general indicator system for cultural services(landscape recreation, education), we added negative oxygen ions and health care indicators and introduced forest ecosystem service correction coefficients to construct a GEP indicator system and method with unique advantages in forest resources. We evaluated the spatio-temporal variations of GEP in 2010, 2017 and 2020, and quantified the impact of land use/land cover change on GEP by means of elasticity index and value profit and loss analysis. The results showed that the GEP of Zixi County in 2010, 2017 and 2020 was 16.788 billion, 26.817 billion, and 38.407 billion yuan, respectively. Forests contri-buted the largest amount of GEP, followed by wetland, farmland, grassland, and town. During the study period, the added value of GEP mainly came from forest ecosystems. Land use change had an important impact on GEP. From 2010 to 2020, the total land use change area in the study area was 8501.88 hm^(2). The amplitude of land use change was grassland(-2811.17 hm^(2))>town(1428.06 hm^(2))>forest(1357.67 hm^(2))>wetland(1031.05 hm^(2))> farmland(-1005.01 hm^(2)). The absolute changes of various land use types were mainly occurred from 2017 to 2020. The elasticity index of each indicator on forest ecosystems was significantly higher than that of other ecosystems, indicating th
