摘　　要：探究设施蔬菜生产的水土资源消耗特征及耦合压力对实现农业资源的可持续利用具有重要意义。聚焦资源数量及质量,研究核算了2019年山东省设施蔬菜生产的水土资源利用效率,基于空间耦合视角评估分析了水土资源压力及其影响因素。结果表明:(1)全省尺度上设施蔬菜的蓝水足迹平均值为0.08 m^(3)/kg、灰水足迹平均值0.03 m^(3)/kg,设施蔬菜分布受地势影响明显,土壤质量存在显著的空间异质性。(2)设施蔬菜生产水土资源压力耦合协调度属于轻度失调型,平均耦合协调度为0.40,普遍存在水土资源压力的错配情况。(3)除资源禀赋外,社会经济和农资投入也会显著影响设施蔬菜生产水土资源压力的耦合协调程度,且设施蔬菜生产水土资源压力的耦合协调度具有空间溢出效应。研究可为资源压力的综合评估提供新视角,为设施蔬菜生产的水土资源可持续利用与管理提供案例参考。Protected agriculture can break through the constraints of resources and continuously improve the yield per unit area,which has become one of the important patterns of modern agriculture.Simultaneously,its characteristics of high pollution and emissions bring challenges to the sustainable utilization of water and land resources.Previous studies rarely studied the scale effects of protected vegetable production on agricultural water and land resources,and limited studies mostly focused on the quantity of a single resource or non-point source pollution,lacking overall consideration of water and land resources system.It is of great significance to explore the intensity of water and land resources consumption and coupling stress in protected vegetable production for sustainable utilization of agricultural resources.In this study,Shandong province,the largest protected vegetable production base in China,was selected as the case study.It is important for the development of protected vegetable industry in Shandong and even in the whole country to clarify the pressure of water and soil resources and its influencing factors.Considering both the quantity and quality of resources,the water and land resources use efficiency of protected vegetable in 2019 was calculated,and the coupling stress of water and land resources and its influencing factors were analyzed.The results showed that:(1)The mean blue water footprint and mean grey water footprint in Shandong province were 0.08 m3/kg and 0.03 m3/kg,respectively.The layout of protected vegetable was significantly influenced by terrain and the soil quality of protected vegetable has spatial variability.(2)The coupling coordinated subcategory of water and land resources stress in protected vegetable production in Shandong province was the type of slight imbalance,the coupling coordination degree was 0.40,which indicated that there was a common mismatch of water and land resources stress.(3)In addition to resource endowment,agricultural input and socio-economic factors also had s
