Changes Of Nighttime Lights And Their Driving Factors In Inner Mongolia Autonomous Region

Studying the law of urban development space expansion has profound significance for the healthy development of the region and industrial upgrading.Since the reform and opening up,the Inner Mongolia Autonomous Region has been in a stage of great development and transformation.The Inner Mongolia Autonomous Region is located in the northernmost frontier of my country,with vast territory and abundant resources.It plays an important role in promoting new urbanization and improving the development and opening-up layout along the border.For a long period of time in the future,the urban development process of the Inner Mongolia Autonomous Region and the various problems it brings will become the focus of the sustainable development of our society.In order to grasp the information of the urban development process of the Inner Mongolia Autonomous Region in time and accurately,based on the problem of the unknown driving factors of the Inner Mongolia Autonomous Region at the current stage of major development and transformation,based on the night-light image data from 2012 to 2017,using numerical statistics,standard deviation ellipse and linear regression methods,Combining the image data of Gaofen No.1 and economic statistical data,the relationship between the temporal and spatial changes of night lights and economic development was analyzed,and the expansion intensity,direction and main driving factors of the development of night lights were explored.Research indicates:(1)2012-2017 Inner Mongolia night light changes have obvious stage characteristics,and the night light change intensity presents a "v" curve;Inner Mongolia night light sub-city change characteristics show that the spatial distribution of night light in Inner Mongolia urbanization is uneven,the main cities It is distributed along the main stream of the Yellow River and the main lines of transportation;the urbanization levels of the east,central and western regions differ greatly,and the night light intensity and urbanization level in the central part are significantly higher than those in the eastern and western parts.(2)The changes of night lights in the city center areas of the Inner Mongolia Autonomous Region are relatively stable,and there are fluctuations in the increase and decrease of night lights in some areas.Among them,the changes of night lights in Ordos City in western Inner Mongolia are the most obvious.(3)From 2012 to 2017,only Ordos City,Bayannaoer City and Ulan Qab City showed a spatial expansion of the night light spatial distribution,and the direction of the night light center of gravity moved to the city of Hubao E in the central region of Inner Mongolia Autonomous Region The group movement shows that the central region of the Inner Mongolia Autonomous Region,especially the Hubao’e City Group,has a strong pulling effect on the economic development of the entire Inner Mongolia Autonomous Region.(4)The areas where lights fall at night are mainly closed mines and some residential areas.From 2012 to 2017,the decline in energy extraction intensity,the waste of energy mining infrastructure and the sharp decline in energy prices were the main reasons for the decline in night light value in the Inner Mongolia Autonomous Region.The development of the Inner Mongolia Autonomous Region is most affected by energy factors,and it is currently leading the development of the entire Inner Mongolia Autonomous Region The dominant factor.
