Explaination of water scarcity situation for Hebei Province

摘要

We choose the region of Hebei as our example to find its water scarcity situation. R-type clustering method is developed to divide the factors of physical and economic scarcity into four parts, hydropower construction investment, effective irrigation area, water consumption per capita and other reasons. Then we invoke Principal Component Analysis (PCA) to determine the weight of each factor. We find the backward hydropower construction situation mainly causes the water scarcity.
