Abstract

Aiming at the problem of water shortage in the world, we set up an index to measure the supply capacity of regional water resources, and chose six regions to verify the accuracy of the index. Then we chose the Beijing area to analyze the causes of water shortage combined with the actual situation. After that, we predicted the water supply situation in Beijing area in the next 15 years and explained the impact of future water resources on the residents’ life by using the grey prediction method. Then the intervention plan is put forward, and the influence of the intervention plan is added to the evaluation model, and then the water supply capacity of the prognosis is predicted again. The quality of the intervention plan is evaluated, and suggestions for future water resources supply are put forward.
