摘要
根据虚拟水理论,采用多目标综合决策的方法,以武威市凉州区的农作制为研究对象,以提高区域农作制的经济效益、生产效益、生态效益为目标,选择用工量、净收益、农产品单位质量虚拟水含量、单位水价值等8个评价指标,对现有不同农作模式进行优先排序.结果表明:凉州区农作模式的优势度依次为葡萄>制种玉米>蔬菜>玉米>啤酒大麦>小麦>薯类>油料,进而得出凉州区应从虚拟水贸易角度出发,优先发展综合效益高的葡萄酒酿造、玉米制种、蔬菜种植等产业,合理安排农产品区际贸易,从区域水资源平衡及水资源高效利用层面上缓解水资源压力.
According to the theory of virtual water,the farming system of Liangzhou District of Wuwei City was taken as research object in order to improve the economic efficiency,ecological benefit and productivity of the farming system.Eight indices were selected such as amount of labor,net income,virtual water contents of agricultural products,unit water value etc.by using the multi-objective decision method to make the priority of the plant industry structure.The results showed that the priority of the plant industry structure as grapescorn for seedsvegetablescornbarleywheatpotatooil seeds.In order to ease the pressure of water scarcity from the regional water balance and the efficiency for use,the district should give priority to the development of the wine,corn for seeds,vegetables and other integrated-effective industries from the perspective of virtual water trade,at the same time,it also should make the reasonable arrangement for the regional trade of agricultural products.
