摘要
以滹沱河石家庄市市区段为例,利用高分辨率卫星影像数据,以多尺度影像分割与面向对象object-ori-ented影像分析方法为主要技术,融入传统分层分类法理论,利用样本多边形对象的成员函数建立训练区,通过监督分类获得滹沱河流域生态要素的空间数据,采用ArcInfo软件对此数据进行分析研究,提出石家庄市区段滹沱河流域不同生态功能区划分方案。
Taking Hutuo River in Shijiazhuang section as example, this paper put forward the ecological regionalization scheme using high resolution satellite image. It utilized the multi-scale image segmentation and object-oriented image analysis method as the main technique and combined traditional classification theory. It set up the training area using the member functions of sample polygon objects, acquired the spatial data of ecological features using supervised classification method, and analyzed the data using Arclnfo soft-ware.
