Land Use Change And Its Driving Factors In Arong Banner In 2009-2016

Land use / cover change is one of the most complex factors of the change of the earth system caused by human beings.At the same time,the land use pattern is the result of the interaction between the landowners' use and the natural conditions.Therefore,it has become a hot topic in the field of land change science to explore the changes in the spatial and temporal pattern of land use and the driving factors of the land use.In the present study,based on the remote sensing image data in2009-2016 and other auxiliary data in Arong banner,Hulun Buir,the Inner Mongolia Autonomous Region,this paper has extracted and interpreted the land use pattern of the region for 2009-2016 years,and further analyzed the change trend of the land use types in the region and the landscape structure of the region for recent many years.And the driving factors of land use change in the region were analyzed based oneconomic data and climate data.The results show that 1)the total area of Arong banner land is1107330.73 ha,and the land use type is dominated by forest.The forest area in the North accounts for more than 50% of the total area of the whole banner,followed by the southern cultivated land,accounting for about 30% of the total area of the whole banner.The area of the flag is more than 15% of the total area of the whole banner,and the other land account for about 5% of the land.2)in the 2009-2016 years,the overall change of land use in Arong banner was not large,and the area of some areas fluctuated.The area of cultivated land decreased first and then increased.The change of garden area is relatively stable,only 1 ha in2014.The area of woodland and grassland is decreasing year by year.The area of urban villages and industrial and mining land,transportation land and other land use area has increased year by year.The area of water and water conservancy facilities has increased by 364.02 hectares in2010-2011 years,and then the year is decreasing year by year.3)From the change trend of landscape index in this area,we can see that the degree of landscape fragmentation is increasing year by year due to the gradual increase of human activities.4)Variance decomposition showed that the economic factors had the strongest effect on the land use change,and the interpretation rate reached 72.9%;the second was the common effect of two,the interpretation rate was 26.9%,and the individualinterpretation rate of the climate factors was very low,only 0.2%.It indicates that socio-economic factors play a leading role in the process of land use change in the region.
