摘要: 明晰社会经济快速转型背景下的“三生空间”演变过程及其生态系统服务效应,对国土空间优化和区域可持续发展具有重要意义。以1980、2000、2018年土地利用遥感监测数据为基础,基于“三生空间”视角,采用地学信息图谱刻画了三峡库区土地利用转型过程,并通过生态系统服务贡献值测度了土地利用转型的生态环境效应。结果表明: 1980—2018年,三峡库区工业生产空间和生活空间面积不断增加,而农业生产空间和生态空间面积逐渐减少;从图谱转移视角分析,1980—2000年间,土地利用格局相对稳定,以未发生转移的图谱单元占主导,而2000—2018年土地利用转型复杂,以农业生产空间与林地、草地生态空间相互转化占主导,城镇化、工业化进程加快是导致农业生产空间、生态空间面积萎缩的主要原因;三峡库区生态系统服务价值在时间上呈先缓慢降低后迅速增加的趋势,在空间上呈“东部高-西部低”的分布特征;生态保护修复工程促进了生态系统服务价值正效应,但经济社会快速发展挤占了大量的农业生产空间、生态空间,加之农田复耕等行为在一定程度上导致了生态系统服务价值负效应。

Abstract: In the context of rapid socio-economic development, eliciting “production-living-ecological” space (PLES) changes with corresponding ecosystem service benefits is critical for national land optimization and regional sustainability. Based on land use data obtained via remote sensing of 1980, 2000, 2018, and from a PLES perspective, we applied geo-information Tupu to depict land use transformations in the Three Gorges Reservoir Area (TGRA) from 1980 to 2018. The ecological/environmental effects of land use transformation were also explored based on the contribution value of ecosystem service. The results showed that both industrial production space and living space had increased from 1980 to 2018, while agricultural production space and ecological space displayed a decreasing trend. From the perspective of Tupu transformation, land use transformation pattern was relatively stable from 1980 to 2000, with the untransformed Tupu unit being dominant. However, with the complex land use transformation from 2000 to 2018, mutual transformation of agricultural production space and forest and grassland ecological space became dominant. Urbanization and industrialization were the main factors contributing to the decreased agricultural production space and ecological space. The ecosystem service value of TGRA initially decreased, then increased temporally, with greater change in the east than in the west. In the study period, ecological protection and restoration projects had positive effects on ecosystem service values, while rapid socio-economic development negatively impacted agricultural production space and ecological space. Combined with second ploughing, socio-economic development negatively impacted ecosystem ser-vice values.

Key words: production-living-ecological space, land use transformation, Tupu feature, ecosystem service, Three Gorges Reservoir Area.
