摘　　要：黄河流域城市群的发展面临着水资源刚性约束强、跨域治理难度大、承载力不足等问题的严峻挑战。采用环境经济核算方法与水足迹评估了关中平原城市群水资源生态系统服务价值,在描述时空演变特征的基础上揭示了社会经济因素对价值变化的驱动作用。结果表明,生态系统服务价值平稳增长,呈现东南部高于西北部的区域差异特点。价值变化受农业总产值与第二产业生产总值的影响较大,城镇化率、旅游人数等也是主要影响因素。建议把生态系统服务价值纳入到城市水治理中,通过调整城市产业结构与人口密度、推进跨域协同等措施加快绿色转型。本文探索性地编制城市群水资源生态系统账户并进行了核算,为突出生态服务功能在水资源保护与利用提供了科学依据。The development of urban agglomerations in the Yellow River Basin faces severe challenges such as strong rigid constraints on water resources,difficulty in cross-regional governance,and insufficient carrying capacity.Using system of Environmental-Economic Accounting-Ecosystem Accounting and water footprints,and the driving role of socio-economic factors on value changes was revealed based on the description of spatial and temporal evolution characteristics.The results presented that the value of ecosystem services increased steadily and was characterized by regional differences,with higher values in the southeast than in the northwest.Value changes are strongly influenced by gross agricultural output and gross secondary industry,and urbanization rate and tourism numbers are also major influencing factors.It is recommended to incorporate the value of ecosystem services into urban water governance and accelerate green transformation by adjusting the scale of urban development and population density,and promoting cross-domain collaboration and other measures.This study explores the preparation and accounting of water resources ecosystem accounts for urban agglomerations,which provides a scientific basis for highlighting the ecological service function in the protection and utilization of water resources in urban agglomerations.
