摘要
运用ERDAS和ArcGIS软件,分析贵安新区土地利用变化情况。2006—2016年来贵安新区城镇面积一直在增加,且2010年至2016年增加速度更快;农田面积一直在减少,2010年至2016年减少速度更快;水域面积稍有减少;林地面积稍有增加;草地面积呈先减少后增加的趋势。从土地利用类型转换上来看,其他类型之间都有相互转换,但以农田和草地转换为城镇最为显著。
In this study we used ERDAS and ArcGIS to analyze the land use change in Gui'an District,Guiyang.The urban area of Gui'an District had been increasing from 2006 to 2016,and the growth rate was faster from 2010 to 2016.The farmland area had been decreasing,and the reduction rate was faster from 2010 to 2016.The water area decreased slightly,the forest area increased slightly,and the grassland area showed a trend of decreasing first and then increasing.There were interconversion among all types of land use,yet the conversion from farmland and grassland to urban land was the most significant.
