摘 要:将生态系统服务纳入国土空间利用效率评估和土地利用决策对推动区域国土空间可持续管理具有重要意义。该研究以黄河流域为例,通过构建顾及不同生态系统服务类型的农业、城镇和生态空间利用效率评估指标体系,借助SBMUndesirable模型、空间自相关分析和空间计量模型等开展县域单元国土空间利用效率评估与影响因素识别。研究表明:1)黄河流域城镇空间利用效率处在效率值小于0.2的极低水平,生态空间利用效率稳定在中等水平,研究期内农业空间利用效率相对较高且效率值从2000年的0.38(低水平)提高到2020年的0.62(高水平)。2)黄河流域国土空间利用综合效率和耦合协调度为低水平和基本协调,2000—2020年有所改善,但2020年仍有70%以上的县域效率综合值低于0.4,20%以上的县域三类国土空间利用效率失调。3)2000—2020年流域农业和生态空间利用效率提升区范围持续减小,城镇空间利用效率提升区范围先增后减,且人类活动和土地利用对国土空间利用效率的影响比自然条件更大,上中下游的效率提升区类型和影响因素存在显著差异。通过对不同效率提升区提出兼顾利用效率提升与生态系统服务改善的国土空间管理策略,可为黄河流域高质量发展和国家生态文明建设提供支撑。Ecosystem services can often be integrated to evaluate the utilization efficiency of territorial space and land use decision-making in the sustainable management of regional natural sources.In this study,an evaluation index system was developed for the utilization efficiency of agricultural,urban,and ecological land spaces.Different types of ecosystem services were also incorporated using the SBM-Undesirable model,spatial autocorrelation analysis,and spatial econometric models.A case study was taken in the Yellow River Basin from 2000 to 2020.A systematic analysis was made on the utilization efficiency of different territorial spaces under ecosystem service-oriented management,as well as their coupling coordination degree and influencing factors.Finally,some recommendations were proposed to identify the areas needed.The results show that:1)There were significant spatiotemporal differences in the utilization efficiency of the three types of territorial space in the Yellow River Basin.The extremely low efficiency in urban land space utilization remained with the values below 0.2.The utilization efficiency of ecological land space was stable at a medium level.The relatively high efficiency of agricultural land space utilization was achieved to increase from 0.38 in 2000(low level)to 0.62 in 2020(high level)during the study period.2)There was a low comprehensive efficiency and coupling coordination degree of territorial space utilization,indicating generally coordinated patterns.Although some improvement occurred from 2000 to 2020,over 70%of county-level efficiency composite values remained below 0.4 in 2020.More than 20%of counties exhibited imbalances in the utilization efficiency of the three land space types.The downstream region shared the highest comprehensive efficiency and coupling coordination degree,indicating a generally coordinated state.There was a consistently declining proportion of counties with severe and mild imbalances.Agricultural spatial efficiency was improved in the middle and lower reaches.As
