摘要
以遥感-地理信息系统为技术支持,以近红外TM遥感影像为主要数据源,建立统一的高斯-克吕格投影坐标系,进行图像裁剪处理;采用非监督分类法、影像数据与武陵山脉基础地形数据融合叠加分析法,对壶瓶山自然保护区森林立地进行人工目视判读;最后运用GIS空间分析法得到森林立地分类及面积。
With remote sensing-geographic information system as the technical support, and using near-infrared TM remote sensing image as the main data somme, a unified Gauss-Kruger projection coordinate system was established to perform image cropping processing.The artificial visual interpletation of the tbrest site of Hupingshan Natme Reserve was carried out by using unsupervised classification method, image data and Wul- ingshan basic terrain data tusion superposition analysis method.Finally, the GIS spatial analysis method was used to obtain the folest site classification and area.
