Abstract

Water is an essential commodity upon which all life on Earth depends. According to the United Nations, one quarter of the world's population experience water scarcity. Serious water scarcity will block social development and endanger human health .In this paper, I establish model to help figure out the problem of water scarcity. In the first part, I used the analytic hierarchy, by looking at the bottom of the data and determine the weight of each layer to calculate the water demand. In the same way, I can get the total amount of water supply, and with (the water supply, the water demand) for the coordinates of the point in the coordinate system of 1 by 1 square area, I introduce a new parameter - the water stress indicator to divided the square area into several small areas. So that I can determine the extent of water scarcity in the region through the location of the point. In the second part, I chose Shandong Province, China as a severe water shortage area, and chose the Liaoning Province and Jiangxi Province as a comparison, bring the data into the model, by its position validates that our model is correct and universal significance. By substituting the three cities' data in, I found that the results obtained are in good agreement with the water map, which means our model is universal and correct. This model can be used to analyze the current situation of water resources in a region, also can be used to predict future trends. The disadvantage is that the water is a necessity of life, so I ignore the impact of price factors on it, which may cause minor errors.
