Space-time evolvement of Guangdong urban-rural integration

In order to evaluate urban-rural integration of Guangdong Province from space-time evolvement angle,urban-rural integration from 2000 to 2012 in Guangdong Province and various cities of the Province in 2010 were quantitatively calculated in principal component analysis and exploratory spatial analysis methods. The results show that in recent years, the development of urban-rural integration in Guangdong Province is quick, however, it is imbalanced between various cities, exitsting an obvious dual-spatial structure. Urban-rural integration development level is poor in the northern and the east and west wings of Guangdong province, and the pearl river delta are the highest. It is a significant positive correlation between spatial difference of urban-rural integration and economic development, location factors, and.urbanization level. Finally, according to the results of evaluation, relevant measures are put forword to promote coordinative development of urban and rural areas.
