摘要：利用张家口退耕区0.6m分辨率的快鸟(QuickBird)遥感影像,进行退耕区新造林地的长势监测。对快鸟影像进行正射校正,运用高斯滤波进行图像增强,减少噪音,增强退耕地的树冠信息。采用面向对象的图像信息提取技术,提取退耕还林地树冠信息,统计树冠面积,计算退耕还林造林成活率。根据实际测量的数据进行误差检验,由遥感数据自动提取的树冠面积平均误差为0.763m2,计算出的成活率精度为89.837%,为退耕还林的规划管理提供科学准确的依据。
The purpose of this paper is to monitor the growth of new planting trees in the cropland being converted to forests in the project of converting cropland to forest using QuickBird high resolution (0.6 m) remote sensing image in Zhangjiakou,Hebei Province. Ortho-rectification has been done for QuickBird image. Gaussian filter was applied to the image to improve the tree crown information and control image noise. Tree crown classifictation of QuickBird data was performed by using object-oriented image analysis,therefore,crown area was obtained and new planting trees survival rate was calculated based on the tree crown classification results. Finally,accuracy inspection had been done according to field measurement data,the results showed that the average error of crown area was 0.763 m2,the accuracy of survivae rate was 89.837%,The study will provide a scientific basis for programming and management of the project of converting cropland to forest.
