摘要
针对退耕还林工程动态监测任务繁重、投入大且人工监测精确性低的问题,在前人研究的基础上,根据退耕还林监测的需求,对遥感数据源的选择、数据的处理过程及在退耕还林监测中的应用做了详细的探讨,较完善地提出了基于遥感技术的退耕还林监测技术。并通过与传统监测方法的对比,得出遥感在退耕还林监测中具有广阔的应用前景。最后,指出多源数据融合和发展新的遥感信息提取方法将是该技术今后的重点发展方向。
The dynamic monitoring of farmland to forests project need launch into much money and in general the result of manual monitoring has a low precision. According to the requirement project monitoring, discuss the monitoring technology of remote sensing from the sides of data sources selection, process and application. Moreover, the paper compares the new technology with conventional method and concludes that remote sensing will have a broad using in dynamic monitoring of farmland to forests project. At last, the paper points out that fusion of multi-source data and new information extraction technology of remote image are the important developing direction of this technology in the future.
