Spatial and temporal dynamic changes of urban land use in typical mountainous areas of northern Guangdong Province
According to the Land Survey Regulations,the state conducts land surveys every 10 years according to the needs of national economy and social development. To date,three national land surveys have been carried out. On the basis of national land survey,it is of great significance to analyze the spatial and temporal dynamic changes of land use for the utilization and scientific management of national land resources. In this paper,Lianzhou City,a typical mountainous city in northern Guangdong Province,was taken as the research area. Landsat remote sensing images in 2009 and 2019 were used,and land use and cover change (LUCC) rate and degree of typical mountainous cities in northern Guangdong Province were analyzed by means of land use dynamic degree and spatial autocorrelation. The results show that over the past 10 years,forest land and cultivated land are the main types of temporal and spatial dynamic changes of land use in the study area;the intensity of land use in the study area is low,and the change is not obvious,and there is a certain spatial differentiation law.
