Spatiotemporal distribution and centre of gravity dynamic change of wild fruit forests in Emin County,Xinjiang from 2007 to 2020
Taking the distribution area of wild fruit forests in Emin County as the research area,using the remote sensing images of Quick bird in 2007 and Gaofen-1 satellite in 2013 and 2020,and the wild fruit forests field measurement data,the information inter-pretation and area extraction of wild fruit forests were realized,and based on the dynamic degree model,transfer matrix model and center of gravity migration model,the temporal and spatial distribution characteristics and dynamic changes of wild fruit forests in the study area from 2007 to 2020 were analyzed,and the mutual conversion between various features and wild fruit forests was mastered.The shift of the center of gravity of the spatial distribution of wild fruit forests was analyzed,and the reasons affecting the temporal and spatial distribution of wild fruit forests in the study area were discussed.The results showed that the area of wild fruit forests increased by 3.91 km2 from 2007 to 2020,which showed a continuous and slow increasing trend,and the development of tourist attractions di-rectly led to the increase of building land area;in the past 14 years,the area of wild fruit foresst increased gradually,which was attrib-uted to the frequent conversion of grassland and bare soil to wild fruit forests,and the transformation of grassland to wild fruit forests was the most significant;the change range of the center of gravity of wild fruit forests was small,and the spatial distribution was rela-tively stable.
