| Abstract: | Northwest China is very short of water resources and its ecological environment is very brittle. With the implementing of the strategy of developing West China, the contradiction between water supply and need becomes more pronounced. Based on 40 years of meteorological data of 91 weather stations and combined with GIS, the dry/wet situation and water surplus/shortage quantity of different regions in Northwest of China are analyzed according to the climatic indices of precipitation, potential evapotranspiration and aridity. The results provide a basic knowledge for rational development and use of water resources in Northwest of China. |

| Keywords: | water resources campaign of developing west potential evapotranspiration aridity |
