多源高分辨率卫星遥感影像监测林地动态变化研究

Monitoring of Forestland Dynamic Changes by Using Multi Source and High Resolution Satellite Remote Sensing Images

以内蒙古大兴安岭克一河林业局、吉文林业局林地动态变化监测为目标,应用多期国产高分辨率卫星遥感数据,辅以德国Rapid Eye、法国SPOT5和SPOT6、美国TM遥感影像;叠加占用征收林地资料、伐区作业设计、林木采伐许可证、林政案件资料、森林资源二类调查以及林地保护利用规划等专题数据资料。通过目视解译与提取识别,检测林地和林木的变化情况,结果表明:卫星遥感影像对林木采伐、占地、毁林开垦和森林灾害监测效果明显。

Keyihe Forestry Bureau and Jiwen Forestry Bureau are located in Daxinganling,Inner Mongolia. The monitoring of forest land changes was conducted by using multi source domestic high resolution satellite remote sensing data,supplemented by Germany Rapid eye,SPOT5 and SPOT6,TM remote sensing image;Such data were also used as those of occupation of forestland,felling area design work,licenses of forest harvesting,forestry administration,forest resources management survey,forest conservation and utilization planning. The dynamic changes of forest land are detected by visual interpretation,identification and extraction of forest land and forest disaster. The results show that the monitoring effect is obvious and effective in monitoring of occupation and requisition of forestland,forest harvesting and deforestation,reclamation of forest land and forest disaster.
