基于GIS的巩义市农村居民点景观格局时空演变研究
Studies on landscape pattern changes of rural residential areas in Gongyi based on GIS
摘要
Abstract
With the data of 1990 and 2008,landscape pattern changes of rural residential areas were studied in Gongyi based on GIS and the method for analyzing landscape pattern. The results show that the changes in rural residential areas can be seen in terms of the scale of growth,density increase and regular shape. The features,size,shape index and density of the rural residential areasanel temporal-spatial evolution were studied on different landforms,levels of economic development,traffic conditions and levels of population density. The area growth rate of the rural residential areas is fastest in mid-low mountains. The reduction rate of the figure index of rural residential areas is fastest in hilly region. The density growth rate is fastest in the mountainous regions. The faster social economy develops,the slower the area growth rate becomes and the faster the reduction rate of the figure index becomes. The nearer to G310 road,the slower the area growth rate will be and the faster the reduction rate of the figure index,as well as the density growth rate. The area growth rate,the reduction rate of the figure index and the density growth rate are fastest in the mid-leveled population density areas.关键词
