Research on Model of Water and Climate Change in China

Abstract

In this paper, we studied a problem about the world’s water especially the present situation of water resources through Analytic Hierarchy Process (AHP). According to AHP, we build a main model called Water Supply Capacity, and set up two auxiliary model which are called Sewage Disposal Model and the Grey Forecast Model. The Water Supply Capacity Model indicates a measure method about water supply capacity among a region. The Grey Forecast Model is used to do the fitting and prediction to coordinate our study. Finally, we designed a formula to evaluate the water supply capacity and drew some conclusions about how to relief the drought in China. Those models include many factors, such as time, rainfall, groundwater, surface water, administration and so on. Meanwhile, all the data used in our paper are derived from reliable way, such as National Bureau of Statistics of the People’s Republic of China. So that our model is credible and practical.
