摘要
对2008年SPOT5遥感图像进行相关处理,在GIS平台上,采用人机交互式解译的方法,提取出2002～2005年大仓乡京津风沙源工程区小班信息,并通过抽样进行实地调查验证,解译精度达到要求。将解译结果与各年实际造林数据进行比较,工程造林总体保存率达84.97%。结果表明,该方法能够准确、高效、快捷地提取工程区信息,为应用"3S"技术辅助开展京津风沙源工程监测提供了科学依据。
After processing the satellite remote sensing SPOT5 image in 2008, the subcompartment information of the project in Dacang Town, Duolun County from 2002 to 2005 was extracted by the computer classification and the man-machine interactive classification on the platform of GIS. Field survey verified by sampling, the interpretation precision can meet the requirements. Comparing the interpretation result with the actual afforestation data, the overall survival rate of the project afforestation reached 84.97%. The result indicated that this method can accurately, highly-effective withdraw the afforestation information of the project area quickly, and provide the scientific basis for 3S technology in carrying out the Beijing and Tianjin sandstorm source project monitoring auxiliary.
