Study on Population Development and Carrying Capacity of Water Resources and Land Resources in China-Taking the Next 10 Years as an Example

摘要

The article takes the next 10 years as the research period to explore the challenges that water resources and land resources will face in the context of the universal two-child policy in China.By adjusting the population parameters in the policy context and using CP PS population forecasting software to predict the population size in the next 10 years,we find that the total population of China will continue growing in the next 5 years.In the next 10 years,the urban population will decrease very slightly after the increase for 7 years,reaching a peak in 2027,and the increase will cause deepening urbanization.It is necessary to take countermeasures to cope with the problem of the carrying capacity of water resources and land resources brought about by the growth of the total population and the deepening of urbanization under the influence of the universal two-child policy effect,so as to achieve the harmonious development of population growth and urbanization with ecological environment.
