摘要: 探讨景观生态风险与生态系统服务价值之间的关系,对于构建生态安全格局和促进人类福祉具有重要意义。以福建省为研究区域,利用1980、2000和2020年3期土地利用遥感监测数据,基于5 km×5 km评价网格重采样,定量评估景观生态风险和生态系统服务价值,分析二者的时空变化特征,采用双变量空间自相关分析方法和空间回归模型分析二者的空间关系。结果表明: 1980—2020年,福建省景观生态风险等级由中等风险转入较低风险,风险状况转好,各等级总体呈现东高西低的分布格局;生态系统服务价值总体下降,各单项生态系统功能结构相对稳定,各等级由高到低以高值区为核心向外依次扩散分布。景观生态风险与生态系统服务价值存在显著的空间负相关性,景观生态风险对生态系统服务总价值具有负效应,对供给功能价值的影响最大。

Abstract: Understanding the relationship between landscape ecological risk and ecosystem service value (ESV) is important for building an ecological security pattern and enhancing human well-being. Taking Fujian Province as the research area, based on the remote sensing monitoring data of land use in 1980, 2000, and 2020, we carried out a grid resampling size of 5 km × 5 km in the study area, quantitatively evaluated the landscape ecological risk and ESV, and analyzed the spatio-temporal variations. The spatial correlation between landscape ecological risk and ESV was investigated by using the bivariate spatial autocorrelation analysis and the spatial regression models. The results showed that the landscape ecological risk level in Fujian Province changed from medium level to low level, with the situation being improved. The landscape ecological risk level was generally higher in the east region and lower in the west region. ESV generally declined. The functional structure of each ecosystem was relatively stable. ESV spread from high to low with high value area as the core. There was a significant negative spatial correlation between landscape ecological risk and ESV. Landscape ecological risk had a negative effect on ecosystem total ser-vice value, with the strongest impact on the supply function.
