| Abstract: | The urban sprawl is an important issue to be solved urgently in the 21st century.The population,environmental and social problems resulting from the urban sprawl has drawn wide attention from governments and academic circles.The characteristics and the main influencing factors of urban construction land expansion in Zhengzhou City were researched and analyzed in this paper.The changes of construction land area is studied in the past 21 years based on the Landsat TM/ETM+ data as one of the main data sources,and using object-oriented and artificial visual interpretation methods combined with land-use map and Google Earth data of Zhengzhou City.On this basis,causal analysis is made between the construction land area and the influencing factors with economic data.The results are drawn as follows.1) Urban construction land area increased from 126.31 km2 in 1988 to 303.59 km2 in 2000.2) Construction land area had a year-on-year increase of 3.1 km2 from 1988 to 2000,with an annual rate of 2.18%.3) Averagely,construction land area expanded by 12.99 km2 per year from 2000 to 2009,with an annual rate of 6.18%.4) Expansion of construction land is dominated by a concentric-style center at February Seventh Square in the two periods.5) The main factors affecting urban construction land expansion in Zhengzhou are the number of urban residents,economic development,and industrial restructuring. |
