基于农作物虚拟水的云南省水资源战略研究

Water Resources Strategy in Yunnan Province Based on the Virtual Water of Crops

在深入研究虚拟水及虚拟水贸易的基础上,结合云南省2011年统计年鉴数据,建立了虚拟水账户并计算了2010年该区各种农作物虚拟水含量,发现粮食作物和糖料作物消耗水资源最多,并且糖料作物携带大量虚拟水出口。因此,进一步从优化农作物种植结构、利用市场经济推动、调整产业结构3方面提出保障云南省水资源战略安全的对策。

Based on the study of virtual water and virtual water trade, and the data of the 2011 Statistical Yearbook of Yunnan, we have established the virtual water accounts and calculated the virtual water content of a variety of crops in this region in 2010. The results show that the cereal crops and sugar crops consume the largest amount of the water resources, while the large amounts of the virtual water in the sugar crops are carried out through export. Therefore, it is proposed to safeguard the water resources in Yunnan in three strategic aspects such as optimization of crop structure, promotion of the market economy and industrial structure readjustment.
