黄河流域粮食虚拟水流动对水资源空间均衡性的影响

采用引力模型、彭曼公式测算黄河流域省区间粮食虚拟水流动量，基于环境、经济、社会维度，通过比较虚拟水流动存在与否情景下的基尼系数，分析黄河流域粮食虚拟水流动对水资源空间均衡性的影响。结果表明：在2018年黄河流域省区间粮食虚拟水流动中，山东、河南、陕西、内蒙古的粮食虚拟水、虚拟蓝水呈净流出；山西、甘肃、宁夏、青海的粮食虚拟水、虚拟蓝水则呈净流入；黄河流域省区间粮食虚拟水流动在环境、经济、社会维度下均一定程度上促进了水资源空间均衡，其中环境维度下的促进作用较为微弱。

Influence of grain virtual water flow on the spatial equilibrium of water resources in the Yellow River Basin

Gravity model and Penman formula were used to measure the grain virtual water flow interprovincially of the Yellow River Basin. Based on environmental, economic and social dimensions, the influence of grain virtual water flow on the spatial equilibrium of water resources in the Yellow River Basin was analyzed by comparing the Gini coefficient under the presence or not of virtual water flow. The results show that in the grain virtual water flow interprovincially of the Yellow River Basin in 2018, the flow of grain virtual water and virtual blue water in Shandong, Henan, Shaanxi and Inner Mongolia were net outflow; those two kinds of flow in Shanxi, Gansu, Ningxia and Qinghai were net inflow. The grain virtual water flow interprovincially of the Yellow River Basin can promote the spatial equilibrium of water resources to a certain extent in the environmental, economic and social dimensions, and the promotion effect in the environmental dimension is relatively weak.
