Study On The Correlation Analysis Model Between The Urbanization And The Development Of Water Resources In Beijing Tianjin Hebei Region

At present,global warming has reached a world consensus.With the acceleration of urbanization,the impact of human activities on climate change can not be ignored.A series of activities,such as the rapid growth of population and the rapid development of economy,have changed the original water cycle process,thus affecting the distribution of precipitation and even the change of the whole climate.The change of precipitation directly affects the amount of water resources.Not only that,with the development of industry and agriculture,the water pollution in Beijing Tianjin Hebei region is gradually aggravating,resulting in the overall shortage of water resources and serious pollution.Based on this,this paper takes Beijing Tianjin Hebei regional urbanization and water resources as the research object,and explores the relationship between urbanization and water resources in the context of climate change,aiming to find out the index factors that influence each other.In addition,this paper uses the regional climate model to simulate the climate change in the past 53 years,and predicts the future climate change,establishes the response model of urbanization under the condition of climate change.This paper mainly completes the following work:(1)studying the current situation of urbanization and water resources in Beijing Tianjin Hebei region,analyze the change trend of precipitation in recent 53 years,and use MK and sliding T mutation test to analyze the mutation of average annual precipitation.(2)dividing 26 meteorological stations in Beijing Tianjin Hebei region into urban and rural areas,and study the impact of urbanization on each meteorological factor in detail.(3)using the data mining algorithm Apriori to establish the correlation model between urbanization and water resources,and explore the relationship between urbanization and water resources.(4)using the regional climate model(precis)to simulate the climate change in 53 years and predict the temperature and precipitation.The response model of urbanization to climate change is established to explore the response of urbanization to climate change.(5)designing and implementing the urbanization and water resources association analysis system,and visualizing the research results.
