红杉树是一种落叶灌木，广泛分布于中国的黄河三角洲。中国丹顶鹤的空间结构被认为对珍稀鸟类的景观和栖息地有影响。本文首先基于SPOT 5融合图像，采用Canny边缘检测和数学形态学算子对中国蚕蛾进行检测。然后计算了中国柽柳斑块的数量、面积、位置和斑块间距。实验结果表明，在断开连通图块后，汉唐图块的检测准确率约为93.4%。约70%的斑块的分布方向大致为南北向。91%的斑块间最小距离在12.5 ~ 57.5m之间。玫瑰花图表明，斑块间的方位角以北-西北为主，其次为东北和东南。研究结果表明，Canny边缘检测与基于数学形态学的圆形和椭圆形目标提取算法相结合的方法简单有效，易于识别汉唐斑块的空间结构，减少了汉唐斑块目视判读的时间和劳动量。
Chinese tamarisk (saltcedar) is a deciduous shrub that occurs widely across the Yellow River Delta in China. The spatial structure of Chinese tamarisk is believed to have an influence on the landscape and habitats of rare birds. In this study, first, Chinese tamarisk is detected using Canny edge detector and mathematical morphological operators based on SPOT 5 fusion-ready imagery. Then the numbers, areas, locations, and patch spacing of Chinese tamarisk patches are calculated. The experiments show that the detection accuracy of Chinese tamarisk patches is about 93.4% after the disconnection of connected patches. The distribution orientation of about 70% of the patches is approximately south–north. About 91% of the minimum distances among the patches are between 12.5 and 57.5 m. The rose graph indicates that the main azimuth between patches is north–northwest, and the second is northeast and southeast. The present study indicates that the integrating Canny edge detector with the algorithms for extracting circular and elliptical objects based on mathematical morphology is simple and effective for detecting Chinese tamarisk patches and is easy to identify the spatial structure of Chinese tamarisk patches, which reduces the time and labor for the visual interpretation of Chinese tamarisk patches.
