| 深入研究生态系统服务供需的时空演变特征及其多尺度的空间匹配模式,对实现生态系统服务有效管理和制定科学的生态保护规划至关重要.以湖北省为研究区域,基于土地利用、气象和社会经济等多源数据,利用InVEST等多种生态模型,对湖北省碳存储、产水、土壤保持和粮食供给这4种生态系统服务供需进行量化和空间分布的刻画,综合分析了2000~2020年间生态系统服务供需和不同尺度下生态系统服务供需比的时空演变特征,并使用GeoDa中双变量Moran's I模块进一步探讨2000~2020年间4种生态系统服务供需空间匹配模式的变化与不同尺度下2020年4种生态系统服务供需空间匹配模式的差异.研究结果表明：①2000~2020年间,湖北省4种生态系统服务供给总量均呈增长趋势；需求总量上,除粮食供给服务外,均呈增长趋势.除土壤保持服务外,其余3种服务均处于供过于求的状态. ②除土壤保持服务外,其他3种服务均呈现出城区供需比值低、非城区供需比值高的两极分化格局,并且在研究区间内,这一格局逐步加深. ③4种生态系统服务供需空间匹配的区域规模及程度差异明显. ④不同尺度下的生态系统服务供需平衡与匹配分析结果存在较大差异.研究结果可为推动湖北省生态系统服务供需格局优化和制定更为准确、详细的生态保护规划提供科学依据,促进湖北省可持续发展. |

| In-depth study of the spatiotemporal evolution characteristics of ecosystem service supply and demand and their multi-scale spatial matching patterns is crucial to achieving effective management of ecosystem services and formulating scientific ecological protection plans. Investigating the Hubei Province as a research region, this study employed diverse ecological models, such as InVEST, based on multiple data sources encompassing land use, meteorological conditions, and socio-economic factors. The objective was to quantitatively assess and spatially characterize the supply and demand dynamics of four ecosystem services-namely, carbon storage, water yield, soil conservation, and food provision-within the Hubei Province. A comprehensive analysis was conducted on the spatiotemporal evolution characteristics of ecosystem service supply and demand, as well as the supply-demand ratio of ecosystem services at different scales, from 2000 to 2020. The bivariate Moran's I module in GeoDa was used to further explore the changes in the spatial matching patterns of four ecosystem services supply and demand between 2000 and 2020, as well as the differences in the spatial matching patterns of four ecosystem services supply and demand at different scales in 2020. The research results indicated that： ① Between 2000 and 2020, the total supply of the four ecosystem services in Hubei Province exhibited an overall increasing trend. Regarding total demand, all services, except for food supply, showed a growing trend. Except for soil conservation services, the other three services were in a state of oversupply. ② Except for soil conservation services, the other three services exhibited a polarized pattern with lower urban-rural supply-demand ratios and higher non-urban-rural supply-demand ratios. This pattern deepened progressively over the study period. ③ Significant regional variations were observed in the spatial matching of supply and demand for the four ecosystem services. ④ There were notable differences in the balance and matching of ecosystem service supply and demand at different scales. The research results can provide scientific basis for promoting the optimization of the supply and demand pattern of ecosystem services in Hubei Province and formulating more accurate and detailed ecological protection plans, promoting sustainable development in Hubei Province. |
