摘要
旨在研究主被动遥感结合的地表覆被变化监测方法,使用高分数据和哨兵1号数据分别代表被动和主动遥感,对新疆西天山国家级自然保护区地表覆被变化情况进行检测,进而对得出的林地、草地、建筑物检测结果进行联合分析,最终得到主被动遥感联合变化检测结果。通过实地精度检验对主被动遥感联合变化检测结果进行验证。结果表明,该方法的变化检测结果精度达到90%以上。说明结合主动遥感和被动遥感既能克服天气的影响,又能在检测中保留光谱和纹理等丰富的信息,变化检测的精度较高;主被动遥感联合变化检测可以较为快速、准确地掌握地表覆被类型的变化,能够在一定程度上减少被动遥感数据的云量困扰。并且该方法在林地和建筑物上有较高的敏感性,适合森林自然保护区的森林变化和建筑监测。
The purpose of this study was to find the monitoring method of land cover change combined with active and passive remote sensing.GF-1 data and Sentinel-1 data that stand for active and passive remote sensing,respectively were used for land cover change detecting in West Tianshan National Nature Reserve in Xinjiang,then the two kinds of the results about the changes of buildings,grassland and forest were combined and analyzed before the final change detection results were obtained.The results accuracy of the method acquired by field survey was more than 90%.The results showed that the combination of active remote sensing and passive remote sensing could not only overcome the influence of weather,but also retained rich information such as spectrum and texture in detection,and the accuracy of this method was high.The change detection method of active and passive remote sensing combination could grasp the changes of surface cover type quickly and accurately,and reduce cloud disturbance of passive remote sensing data to some extent.The method is sensitive to forest land and buildings,resulting in a suitable way for forest change monitoring and building monitoring in forest nature reserve.
