Study On Land Use Change In Uxin Banner

At present,researchers trying to analyze land use change and its driving forces is less.Therefore,taking the remote sensing images in 2007 and 2016as the research object,this paper analyze the land use change and its driving forces in Uxin Banner.The results show that:(1)In 2007,the order of all kinds of land use in Uxin Banner was grassland>unutilized land>woodland>cultivated land>water area>construction land,which is consistent with that in 2016.It shows that the study area is the interlaced zone of grassland and unused land,agriculture and animalhusbandry.(2)The main characteristics of land use types transformation in Uxin Banner are the conversion of grassland and unused land and the conversion of grassland and woodland.From 2007 to 2016,92,154 hm~2 of grassland was converted into unused land,79,661 hm~2 of unused land was converted into grassland,52,369hm~2 of woodland was converted into grassland,and 47,850 hm~2 of grassland was converted into woodland.(3)During the study period,land use types in Uxin Banner varied greatly in construction area,increased 5936hm~2,followed by cultivated land and unutilized land,increased 5056hm~2 and 5776 hm~2 respectively,and again grassland,reduced 17946hm~2,with annual changes of 16.98%,2.09%,0.27%,-0.23%respectively,water area and woodland remained basically stable.(4)From 2007 to 2016,the land use level of Uxin Banner was relatively small,and the amount of change and rate of change of land use were 0.96 and0.52%respectively,indicating that the land use of Uxin Banner was in a development period in recent 10 years,and the land use development was slow.(5)In the 10 years from 2007 to 2016,the landscape pattern has obvious changes,the landscape diversity index decreased from 1.22 in 2007 to 1.15in 2016.As the landscape became more and more single,the diversity of landscape decreased,and the landscape was occupied by a few types of land.As a result,the uniformity of the landscape increased,the evenness index rose from 37%to 52%.The landscape dominance index of Uxin Banner in 2007was 1.37 and increased to 1.43 in 2016.The values of the patch densities in2007 and 2016 were all small,indicating that the ductility or reunion level of various plaque types was low,the degree of spatial heterogeneity was larger,and the connectivity among the patch types was poor.The plaque index of grassland was the largest,indicating that Uxin Banner matrix for the grassland.Generally speaking,the study area landscape use was not very rich, fragmentation was relatively low,landscape dominance was not high,the landscape had no advantage type,but the distribution of each type of plaque was uniform.(6)Using the qualitative and quantitative analysis method,this paper identified 13 related land use driving factors in Uxin Banner.Through principal component analysis,determined the main driving forces of land use change in Uxin Banner are:population growth,economic development and scientific and technological progress.(7)After analyzing the regional situation,this paper discussed the way of sustainable land use in Uxin Banner.
