Expansion of Urbanization Based on Remote Sensing Technology Research to Zhengzhou City as an Example
Taking the region around Zhengzhou as a study area, the urban building information was extracted from TM images of 2006 and 2010 through the decision tree method. On the whole, the result of extraction is satisfactory. The overall quality coefficients of urban building information were all above 0. 89. From 2006 to 2010, the area of urban building has increased from 196.2 km2 to 279.5 km2; a net increase ratio of the urban building in the study area was 42.4%. Urban building has presented the trend of expansion from the center of the city. The main direction of expansion in the west and northeast whiles the expansion in the other directions evenly. The factors of traffic, population, economic were thought to be the most important driving force of urban expansion.
