我国地区农林牧渔业虚拟水流动格局研究——以经济区域与省区为空间尺度

Pattern of Chinese Regional Virtual Water Flow in the Agriculture,Forestry,Animal Husbandry and Fishery Industry——In the Spatial Scale of Economic Regions and Provinces

基于多区域投入产出法,细分42个经济部门及30个省区(由于样本数据缺失,未涵盖西藏),以经济区域与省区为空间尺度,系统分析了我国各地区农林牧渔业虚拟水流动的空间及需求格局。结果显示:西北区域尤其是新疆农林牧渔业虚拟水流动活跃程度高于我国其他地区。各经济区域(或各省区)该部门虚拟水流出均主要流向国内其他地区;多数地区对应流入均主要源自进口,多数区域及省区农林牧渔业虚拟水均呈现净流入。城镇居民消费是经济区域农林牧渔业虚拟水国内流动以及省区对应国内流出的主要需求。

Based on the multi-regional input-output method, with the distinction of 30 provinces （excluding Xizang） and 42 economic sectors, this paper systematically anayzes the spatial and demand pattern of regional virtual water flow of the agri- culture, forestry, animal husbandry and fishery industry, in the scale of economic regions and provinces. Results show that the virtual water of the agriculture, forestry, animal husbandry and fishery industry in the Northwest Region, especially Xin- jiang, flows more actively than other regions. The virtual water outflow of this sector in every economic region or province mainly directs at the other regions in China. The sectorial virtual water inflow in most regions primarily comes from import. Most regions show net seetorial virtual water inflow. The consumption of urban residents is the primary demand of either do- mestic sectorial virtual water flow in any economic region or the provincial domestic outflow.
