摘　　要：以盐城市为研究区域,基于1990-2020年4期地表覆盖数据,在“三生空间”框架内分析了其时空分布变化趋势及关系,采用ESV估算模型和InVEST模型,探究了空间转型对该区域生态系统服务中的生境质量、碳储存量以及生态系统服务价值的影响,以期为盐城市及同类地区国土空间资源的可持续发展提供借鉴。研究表明:(1)盐城市“三生空间”中的生产、生活及生态空间用地占比分别为80.1%、7.9%和12.0%,1990-2020年30 a间,生产空间面积持续减少,生活、生态空间面积持续增加。(2)盐城市1990-2020年各项生态系统服务指标中以生态服务为目标的碳储存总量逐渐下降,以安全服务为目标的生境质量总分值逐渐下降,以经济服务为目标的生态系统服务价值较为稳定。(3)盐城市1990-2020年“三生空间”生态系统服务综合评价空间平均分逐年下降,其中生态空间为0.439分,生产空间为0.406分,生活空间为0.212分,生产空间生态系统服务综合总得分的减少量大于生活空间生态系统服务综合总得分的增加量,再加上生态空间综合得分的减少,共同导致了该区域30 a来生态系统服务综合评价得分的减少。Base on the land cover data of four periods in Yancheng City from 1990 to 2020,the spatiotemporal distribution changes and correlation were analyzed within the framework of production-living-ecological space,and ESV estimation model and InVEST model were used to explore the effect of spatial transformation on habitat quality,carbon storage and ecosystem service value of ecosystem services in the region,so as to provide reference for the sustainable development of land space resources in Yancheng City and similar areas.The results showed that:(1)The proportion of production-living-ecological space in Yancheng City was 80.1%of the production space,7.9%of the ecological space and 12.0%of the living space.During the 30-year period from 1990 to 2020,the area of production space continued to decrease and the area of living and ecological space continued to increase.(2)From 1990 to 2020,the total amount of carbon storage targeted at ecological services in Yancheng City gradually decreased,the total score of habitat quality targeted at safety services gradually decreased,and the value of ecosystem services targeted at economic services was relatively stable.(3)From 1990 to 2020,the average score of the comprehensive evaluation of ecosystem services in Yancheng City decreased year by year,including ecological space(0.439),production space(0.406)and living space(0.212).The decrease of production area was greater than the increase of living space area,and the decrease of the comprehensive evaluation score of ecological space together led to the decrease of the comprehensive evaluation score of ecosystem services in the region in the past 30 years.
