A Study on the Correlation between Urbanization and Water Resource Load of Bijie City, Using the STRIPAT Model
To verify the correlation between urbanization and the consumption of water resources,this paper quotes STRIPAT model and the kuznets curve to analyze the water resource load quantitatively and its relationship between social and economic factors,such as population (Pi),urbanization (Ui),GDP(Ai) and technology (Ti).Through ridge regression model,the coefficient of four variables (Pi,Ui,Ai,Ti) are available.From the research,three results are available.If the population (Pi),urbanization level (Ui),GDP (Ai) and technology (Ti),each of the four independent variables changes by 1％,it will cause the water resource load to change by-0.200 8％,0.316 2％,-(0.041 9％-0.004 2％ ln Ai),0.200 8％,or 0.014 0％.the urbanization coefficient of quadric is positive,showing that kuznets curve does not exist.It compares the positive and negative effects of the economic growth and technological progress on the environment load.Based on the above research,the paper reaches the conclusion that Scheme 5 in the six schemes is the most suitable developing pattern for a city.In Scheme 5,if GDP is in the rapid growth trend,the population keep the medium growing speedthe bijie city water consumption is 781 036.93 ×104 m3 and 771 746.4× 104 m3 respectively.Water environmental load is the lowest at this time.
