摘要:

当前,将生态风险(Ecological risks, ERs)和生态系统服务(Ecosystem services, ESs)纳入实践应用和政策制定的研究日益增加。然而,综合考量ESs和ERs并运用于实际决策中的研究依旧缺乏。本研究利用InVEST模型和景观生态风险模型,通过CMIP6不同情景下气候变化和土地利用变化驱动,模拟了2000-2100年黄河上游生态系统服务(碳储量、产水量、生境质量,和土壤保持)和生态风险的时空动态变化,并梳理了它们之间的关系。主要研究结果表明,2000-2020年,该区域ERs面积减少了27673 m2,但在SSP1-2.6、SSP2-4.5和SSP5-8.5情景下,预计ERs将分别增加13273 m2、438 m2和68 m2。在过去和未来情景中ESs和ERs均存在显着的空间差异。其中,黄河源区的ESs高,ERs低(p<0.001),而黄河上游东北部ESs低,ERs高 (p<0.05)。总结而言,提出的关于提高生态系统服务和降低生态风险的空间优化框架,可为区域可持续发展提供理论支持。

Abstract:

There is growing interest in introducing ecological risks (ERs) and ecosystem services (ESs) into environmental policies and practices. However, the integration of ESs and ERs into actual decision-making remains insufficient. We simulated the spatiotemporal dynamics of ESs (e.g., carbon storage, water yield, habitat quality, and soil conservation) and ERs in the upper reach of the Yellow River (URYR) from 2000 to 2100. Additionally, we explored their relationships by combining the InVEST model and a landscape ecological risk model with CMIP6 data. Our main findings showed that regional ERs change in response to land use and environmental dynamics. Specifically, the ER area decreased by 27,673 m2 during 2000-2020, but it is projected to increase by 13,273, 438, and 68 m2 under the SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios, respectively. We also observed remarkable spatial differences in ESs and ERs between past and future scenarios. For instance, the source area of the URYR exhibited high ESs and low ERs (P<0.001), while the ESs and ERs are declining and increasing, respectively, in the northeastern URYR (P<0.05). Finally, we proposed a spatial optimization framework to improve ESs and reduce ERs, which will support regional sustainable development.
