Study on Spatial Pattern Evolvement and Features of Rural Settlement Based on GIS

Taking the rural settlement distribution information of Chengdu Longquanyi district as a database which was set up by RS images of 2005and 2010,GIS and spatial analysis model were used to quantitatively analyze the temporal and spatial distribution characteristics of rural settlement and its evolvement rule.The results showed that there were significant difference in rural settlement spatial distribution between 2005and2010compared with the rural settlement quantity of each grid which number was 380and scale was 2.34km2.Second,by calculating the nearest neighbor statistics,the rural settlement spatial distribution of 2005showed significant dispersion trend in general,while the 2010presented clumped pattern but insignificant in terms of statistics.Third,the quantity of rural settlement was decreasing and its spatial distribution morphology trended to agglomeration in 2010compared with 2005.This research can provide decision-making basis for rural settlement arrangement and application reference for new countryside construction,increase and decrease of urban and rural construction land planning,rural land integrated consolidation and so on.
