[Abstract]:Based on the Labdsat5 TMN Landsat8 OLI satellite remote sensing data and the object-oriented classification method, the distribution range of the administrative units above county level in Liaoning Province in 1990 and 2013 is extracted. The characteristics of urban area expansion in Liaoning Province in the past 20 years are analyzed. The results show that the urban area of Liaoning Province increased by 1 122.2 km / m during 1990-2013, and the urban area of 31 cities above the county level has been expanded, with the lowest expansion rate in Fengcheng City. The urban area increased 10.29%, the largest expansion was Donggang City, and the urban area increased 616.84; the absolute value of Shenyang's expanding area was relatively largest, 250.87 km2; Liaoning's urban area could be divided into four types according to the expansion mode: centralized concentric circle expansion mode, Along the main external traffic axis the belt expansion mode, the jump group expansion mode, the low density continuous spread mode, the economic growth, the population increase, the transportation traction, The implementation of the policy has contributed to the large-scale expansion of the urban area of Liaoning Province. In the 23 years from 1990 to 2013, the gross domestic product of Liaoning Province increased by 27 times, and the total foreign direct investment increased by 31 times in the 20 years from 1990 to 2010. It is suggested that in the process of urban development in the future, the urban scale should be properly controlled and the urban area should be expanded in an orderly manner.
