| 摘 要： | 以乌兰布和沙漠的航空遥感图像为基础，对其阈值分割，并选取适当的结构元素进行数学形态学的运算，从而达到对遥感图像边缘提取的目的。利用Matlab7．0软件对研究区域进行图像处理分析，通过提取的边缘和原始图像对比，验证其方法的可行性和有效性，为乌兰布和沙漠地区具有代表性的稀少且呈群团状大样地植被调查提供技术参考。

| Abstract: | Based on the airborne remote sensing image in Ulan Buh Desert, the threshold was segmented and the appropriate structuring elements were selected to conduct mathematical morphology calculation so as to finish edge detection from the remote sensing image. The image processing and analysis in the study region by using Matlab 7.0 were conducted and through contrasting the edge detection and original image, feasibility and effectiveness were verified to provide technical reference to investigate scarce and mass-like vegetation in the Ulan Buh Desert. |
