Abstract
Based on the background of water shortage in Ningxia region, this paper studies the current situation and development prediction of water resources in China and establishes a regression analysis mode. Firstly, the current situation and major problems of water resources development and utilization in China were analyzed with Excel. Secondly, the regression model is established to predict the total national water consumption in 2020 and 2030, the results of the model prediction are compared with the national goals of 2020 and 2030. Finally, the ARIMA model was established by SPSS software to predict the time series and obtain the national and provincial water resource management and control and development trends in 2020 and 2030.

Based on the background of water shortage in Ningxia region, this paper studies the current situation and development prediction of water resources in China and establishes a regression analysis mode
According to the water resources bulletin 2012-2016, China's surface water resources and groundwater resources have little change each year, precipitation is greatly affected by other factors such as climate
For industrial water use efficiency in different parts of the situation, in a study period, the region may be at an early stage, may be a stage of development, gradually to the late stage of development, it is possible that the experience of development, early and late three times, so this article take the various types of mathematical curve model to fitting was carried out on the water consumption per ten thousand yuan of value-added by industry series
Summary
More people and less water and uneven spatial and temporal distribution of water resources are China's basic national conditions and water situation, the shortage of water resources, serious water pollution and deterioration of water ecology are very serious problems, which have become the main bottleneck of economic and social sustainable development. With the further development of industrialization and urbanization, the demand for water resources will continue to grow over a long period of time, the contradiction between supply and demand of water resources will be more acute, and the situation of water resources in China will be more serious. According to the water resources bulletin 2012-2016, China's surface water resources and groundwater resources have little change each year, precipitation is greatly affected by other factors such as climate. Situation in our country, from the national surface water exploitation and utilization of significantly more than the development and utilization of groundwater, mainly composed of surface water and groundwater is complementary, but different from the north-south geographical position, exploitation and utilization of six in the north area of surface water and groundwater development and utilization of a smaller gap was basically use at the same time, the status of exploitation and utilization of six in the south area of surface water and groundwater development and utilization of the gap is great, basic is in a state of only the surface water
