摘　　要：为了分析高速公路出入口周边土地利用随其建成时间的变化规律,以湖南省建成时间较早的19个出入口为研究对象,以1995、2000、2005、2010和2015年5期土地利用数据为基础,基于GIS分析计算土地利用强度和土地利用动态度,分析其随出入口建成时间的变化规律,并使用非参数检验验证相关结论.结果表明:1)出入口周边影响区的土地利用强度和土地利用动态度明显高于非影响区,在建成时间超过15 a后相关指标达到非影响区的2~3倍;2)影响区内的土地利用转化主要为耕地和生态用地向建设用地的转化,且在2010-2015年,影响区内的土地利用转化全部为耕地和生态用地向建设用地的转化;3)影响区内的土地利用强度和土地利用动态度随着出入口建成时间的增长而不断变大,通过Kruskal-Wallis检验,发现不同时间段的相关参数存在显著差异.In order to analyze the variation of land use around expressway entrances and exits with the completion time,19 entrances and exits built earlier in Hunan Province were taken as the research objects,and the land use data of the five phases in 1995,2000,2005,2010 and 2015 were used.The land use intensity and dynamic degrees were calculated respectively based on GIS analysis,and the variation with the completion time of the entrances and exits were analyzed.Finally,the results were verified by nonparametric test.The results show that:1)The land use intensity and dynamic degrees of the affected zone of the entrances and exits are obviously higher than those of the non-affected zone,and these indexes are 2~3 times those of the non-affected zone whenthe completion time exceeds 15 years.2)The land use transition in the affected zone is mainly the transformation of cultivated land and ecological land to construction land.From 2010 to 2015,all land use transition in the affected zone is the transformation of cultivated land and ecological land to construction land.3)The land use intensity and dynamic degrees in the affected zone continue to increase with the completion time of the entrances and exits.And there are significant differences in the indexes in different periods by using the Kruskal-Wallis test.
