Spatial and Temporal Characteristics of Urban Expansion and Green Space Pattern Evolution in Xinjiang for the Past 35 Years
Urban expansion will lead to the reduction of green spaces and the degradation of ecological functions,especially in the arid and water-scarce cities in Xinjiang.It is urgent to carry out quantitative research on urban expansion and green space pattern evolution.Using remote sensing data,this paper quantifies the changes in impervious surface area and its proportion,green space area and its proportion,and green space fragmentation in Xinjiang as a whole,cities that Production and Construction Corps are stationed and cities without the corps from 1985 to 2020,analyzes the evolution characteristics of urban expansion and green space pattern in Xinjiang,explores the development differences between Corps stationed cities and non-Corps stationed cities,and provides scientific support for sustainable development in the western region.The results show that:1)The impervious area in cities of Xinjiang continues to increase from 379.89 km2 to 4 947.60 km2 in the past 35 years,and the area of green space decreases from 408 800 km2 to 393 100 km2,with the fragmentation of green space decreasing first and then increasing;2)The integrated development of the corps and local government has accelerated the urban expansion of the region,especially the expansion of cities in which the crops are not stationed;and 3)In the past 35 years,the green space area in cities where corps are not stationed has continued to decline,while the green space area of corps stationed cities continued to rise before 2010 and decreased rapidly from 2010 to 2020.In the future,the integrated crops-local development in Xinjiang needs to pay more attention to green space development in order to achieve high-quality and sustainable development.
