Study on Optimization of Water-Intensive Industrial Layout from Perspective of Virtual Water Strategy

From the perspective of virtual water strategy, and the method of quantitative model was utilized, this paper has constructed an agricultural and industrial production layout diagnosis and adjustment model under the background of virtual water strategy, and then taking the 14 areas of Hunan Province as the object of study, it diagnosed the matching relationship between the industry and agriculture production and water resources scientifically. The result shows that there has a bigger difference between the situation of Hunan agriculture layout and its ideal layout mode which is under the background of virtual water strategy. Among the 14 areas of Hunan, the agricultural layout is overcrowding in Changsha, Zhuzhou, Xiangtan and Yueyang. However it is too sparse in the region of Xiangxi, Huaihua, Zhangjiajie and Yongzhou. As a whole, the main task that adjustment of Hunan agricultural structure based on virtual water strategy is to increase layout density of agricultural production, and the matching relationship between Hunan industrial layout and water resources is not ideal. And among them, the industrial layout of 6 areas contained Changsha, Xiangtan, Loudi, Zhuzhou, Hengyang and Chenzhou is dense, where insufficient water supply and seasonal water shortages has been happened or it is most likely to appear in the future. In contrast, the industrial layout of 7 zones including Zhangjiajie, Yongzhou, Xiangxi, Yueyang, Yiyang, Huaihua and Shaoyang is too sparse. What’s more, they should have augmented the density distribution of industry and made full use of regional water resources.
