摘要
选取赤峰市区2003、2009、2013和2018年的Landsat TM/OLI遥感影像,利用支持向量机法分类法提取4个年份的中心城区,结合GIS空间分析方法研究城区扩张强度、速度在时间尺度下的变化趋势。结果表明:2003~2018年间,赤峰市中心城区由高速扩张转向低速发展,城镇化率由3.89%上涨至20.55%。
Landsat TM/OLI remote sensing images from 2003,2009,2013 and 2018 were selected in Chifeng,Support Vector Machine(SVM) method was used to extract 4 years of central city,the change trend of urban expansion intensity and speed was studied combining GIS spatial analysis method on time scale,the results showed thatthe central urban area of chifeng changed from high-speed expansion to low-speed development,the urbanization rate rose changed from 3.89% to 20.55% from 2003 ~ 2018.
