Abstract
不透水面的分布规模、空间格局和变化是影响区域生态系统和环境变化的重要指标。Landsat 8卫星的成功发射使得基于Landsat系列遥感影像的陆地生态环境监测及其科学研究得以延续。本研究以该卫星搭载的陆地成像仪(OLI)影像为遥感数据源,基于植被-不透水面-土壤(V-I-S)模型,采用最小噪声分离法(MNF)和支持向量机(SVM)相结合的方法实现地表信息遥感影像分类,并提取高反照和低反照覆盖初步提取不透水面,利用遥感指数去除水体、阴影等干扰物后,得到研究区不透水面的分布现状,在此基础上分析其空间格局。结果表明:相较于TM影像,OLI影像辐射分辨率提高为16bit,其波段范围普遍变窄,影像经大气..
