Research On Water Resources Carrying Capacity And Spatial Distribution Of Population Increment

The research area of this paper is Changji.Changji has a good location and good development conditions.Analyzing the water resources carrying capacity and spatial distribution of population increment in Changji is helpful to promote the population growth in the western region and provide scientific support for the redistribution of the population from east to west in China.The paper constructs the calculation model of water resources carrying capacity of population,per capita water demand forecasting model and environment evaluation model.The paper constructs the calculation model of water resources carrying capacity of population,per capita adequate water demand forecast model and environment evaluation model.The research has got Changji's population carrying capacity and population increment,and extracted the living suitable space.This paper studies the spatial distribution of population increment in Changji Prefecture.The main conclusions of the study are as follows:In recent years,the enhancement of Changji's water supply capacity is beneficial to the development of Changji.The water saving space of Changji's first industrial is very large.Under the world advanced level of water saving and the status of Changji's economic and social development level,the population carrying capacity of water resources is about 2 million 51 thousand and 400 people,an increase of 638 thousand and800 people.Traffic and water are the main factors affecting the spatial distribution of population in Changji.The habitat suitability index of Changji between 6.8~86.7,the average value is 33.9.The total area of habitat suitable space is 15839 km2 across the state.The suitability index is higher in the West than in the East.Suitability index ranking is Manasi County,Hutubi County,Qitai County,Changji City,Fukang City,Jimsar County,and Mori Kazak Autonomous County.Manasi County,Hutubi County,Fukang City,Jimsar county and Qitai county has the potential for population growth.The negative growth of population in Changji city and the amount of Mulei County show that the number of their population has been overloaded,and the environmental pressure of Changji city is biggest.
