Paper Abstract

The paper took TM/ETM+ Landsat images in the year of 1986, 1995, 2000, 2001, 2002 and 2003 as the main information sources and the scopes of Chongqing's construction land during each period were extracted automatically and accurately. The space-time expanding of construction in Chongqing city for the past 20 years was monitored. And then, the motive force mechanism was analyzed combining topographical information data and social economic statistics. The result indicates: Although slope was the limited factor of urban expansion, there was no obvious correlativity with expanding rate in certain ranges. the slope played role to development of city only within a certain period. Expansion rate (y ) of construction land and the population growth rate (x ) present the relation of y = 1.8234x + 0.0763; The area (y ) of the construction land in Chongqing city has close relation with the per capita gross national product (x ) with coefficient correlation up to 0.9878, and they have a mathematical relation of y = 0.03x3-0.6852x2+34.987x+0.015 on number value.
