摘要: 鄂尔多斯市位于黄河几字弯内,明确该区域生态系统服务时空演变特征及其权衡/协同关系,对黄河流域生态保护与高质量发展具有重要意义。本研究基于InVEST模型和遥感数据,评估2000—2020年鄂尔多斯市土壤保持、碳储量、水源涵养及植被净初级生产力(NPP)4项典型生态系统服务,分析其时空演变特征,采用相关分析探究以上4项生态系统服务之间的权衡/协同关系,进一步利用权衡-协同指数和随机森林模型揭示生态系统服务间的权衡/协同作用强度及其驱动因子。结果表明: 2000—2020年,鄂尔多斯市典型生态系统服务整体呈提升趋势,其中,土壤保持总量增加3.47×108 t,碳储量增加0.28×108 t,水源涵养量增加0.76×107 m3,NPP年均值增加349.54 g C·m-2;在所有土地利用类型中,草地和耕地对于区域生态系统服务提升的促进作用最大。除碳储量与土壤保持、NPP之间呈不相关关系外,其余生态系统服务间的关系均以显著协同关系为主,土壤保持、NPP、水源涵养仅在部分地区存在权衡关系;鄂尔多斯市各项生态系统服务间权衡/协同作用关系强度的主要驱动因子为降雨、气温、坡度和人口密度。总体而言,鄂尔多斯市4项典型生态系统服务均呈现良好发展趋势,基于生态系统服务关系分布的时空异质性及权衡/协同作用强度的驱动因素,未来应制定更为适宜的生态系统服务持续提升策略。

Abstract: Ordos City is located within the Yellow River ‘Ji Zi Bend’. Clarifying the spatio-temporal variations and trade-offs/synergies of ecosystem services is of great significance for ecological protection and high-quality development of the Yellow River Basin. Based on the InVEST model and remote sensing data, we evaluated the ecosystem services of soil conservation, carbon storage, water conservation, and net primary productivity (NPP) in Ordos City from 2000 to 2020, and analyzed their spatio-temporal variations. We used correlation analysis to explore the trade-offs/synergies relationship among the four ecosystem services, and further revealed the trade-off/synergy intensity and its driving factors by combing the trade-off/synergy index and random forest model. The results showed that the typical ecosystem services in Ordos City showed an overall upward trend from 2000 to 2020. Total soil conservation increased by 3.47×108 t. Carbon storage increased by 0.28×108 t. Water conservation increased by 0.76×107 m3. The annual average NPP increased by 349.54 g C·m-2. Among all the land use types, grassland and cultivated land had the greatest positive effect on the improvement of regional ecosystem services. Except for the uncorrelated relationships between carbon storage and soil conservation and NPP, the relationships among other ecosystem ser-vices were significantly synergistic. There were trade-offs between soil conservation, NPP, and water conservation in some areas. The main factors driving the intensity of trade-offs/synergies among ecosystem services in Ordos City were rainfall, temperature, slope, and population density. In general, the four typical ecosystem services in Ordos City showed favorable development trends. Based on the spatio-temporal heterogeneity of ecosystem services and the driving factors of tradeoff/synergy intensity, more appropriate strategies for continuous improvement of ecosystem services should be formulated in the future.
