摘要
基于GIS技术和景观格局分析方法,以巩义市G310国道两侧5km缓冲区内农村居民点为对象,研究了1990年和2008年两个时点农村居民点景观格局特点与时空演变。结果表明,农村居民点景观格局特征和景观格局指数动态变化度均受缓冲道路影响,邻近道路的农村居民点主要以原地外延增长为主,远离道路的农村居民点主要以分裂增长为主。
Based on the technology of GIS and the method of analyzing landscape pattern, with rural residential area located within the 5 km distance field of both sides of G310 National highway near the city of Gongyi City as the research object, this paper analyzes the characteristics of landscape and the temporal-spatial evolution of the rural residential area. It is concluded that the landscape characteristics of the rural, residential areas and the dynamical change degrees of the landscape patterns indexes are both influenced by the buffer zone on both sides, with the rural residential areas near the road spreading outward and those far away from the road extending in separation.
