摘要: 识别流域生态系统服务权衡协同关系的时空分异特征及其影响因素,是生态系统管理和调控的重要基础,对高效配置环境资源和合理制定生态环境政策具有重要意义。本研究运用相关性分析、均方根偏差等方法分析清江流域2000—2020年粮食供给、净初级生产力(NPP)、土壤保持和产水服务间的权衡协同关系,并采用地理探测器分析影响生态系统服务权衡的决定因素。结果表明: 2000—2020年,清江流域粮食供给服务呈下降趋势,NPP、土壤保持和产水服务呈递增态势;粮食供给与土壤保持服务、NPP与产水服务间权衡强度呈下降趋势,其他服务间权衡强度均呈增加趋势。粮食供给与NPP、土壤保持、产水服务间呈现东北权衡、西南协同的格局;NPP与土壤保持、产水服务在中部为协同关系、四周为权衡关系;土壤保持与产水服务表现为高度协同。土地利用和归一化植被指数为粮食供给与其他生态系统服务间权衡强度的主导因素,降水、气温和高程为产水服务与其他生态系统服务间权衡强度的主导因素,生态系统服务间权衡强度并非受单一因素的影响,两种服务间的相互作用或共同影响因素的驱动是其决定因素。研究结果可为国土空间生态修复规划策略的制定提供参考。

Abstract: Identifying the spatiotemporal differentiation characteristics of trade-offs/synergies relationships of ecosystem service in watersheds and their influencing factors is essential for ecosystem management and regulation. It is of great significance for the efficient allocation of environmental resources and the rational formulation of ecological and environmental policies. We used correlation analysis and root mean square deviation to analyze the trade-offs/synergies relationships among grain provision, net primary productivity (NPP), soil conservation, and water yield service in the Qingjiang River Basin from 2000 to 2020. Then, we analyzed the critical factors affecting the trade-offs of ecosystem services by using the geographical detector. The results showed that grain provision service in the Qingjiang River Basin presented a decreasing trend from 2000 to 2020, and that NPP, soil conservation, as well as water yield service showed an increasing trend. There was a decreasing trend in the degree of trade-offs between grain provision and soil conservation services, NPP and water yield service, and an increasing trend in the intensity of trade-offs between other services. Grain provision and NPP, soil conservation and water yield showed trade-off in the northeast and synergy in the southwest. There was a synergistic relationship between NPP with soil conservation and water yield in the central part and a trade-off relationship in the surrounding area. Soil conservation and water yield showed a high degree of synergy. Land use and normalized difference of vegetation index were the dominant factors in the intensity of trade-offs between grain provision and other ecosystem services. Precipitation, temperature, and elevation were the dominant factors in the intensity of trade-offs between water yield service and other ecosystem services. The intensity of ecosystem service trade-offs was not only affected by a single factor. In contrast, the interaction between the two services or the common factors behind the two services was the determining factor. Our results could provide a reference for developing ecological restoration planning strategies in the national land space.
