摘要
基于2015年广西壮族自治区森林资源宏观监测遥感群团样地调查结果,分析具有丰富遥感判读经验人员和无判读经验人员在参考不同分辨率、不同时相遥感影像,以及林业经营管理资料的条件下进行判读,各地类的正判率情况。结果表明:经验丰富的判读人员对于乔木林、竹林、特殊灌木林和森林的正判率均高于无判读经验人员;高分辨率和合适时相的遥感影像,以及充分利用林业经营管理资料,均有助于提高正判率。
Based on the forest resources monitor results from remote sensing samples in Guangxi Zhuang Autonomous Region,this paper compared the interpretation accuracy between the experienced interpreters and inexperienced interpreters through the different resolution and remote sensing images of different time phase with the help of forestry management information. Results showed that,the accuracy rate of experienced interpreters were higher than inexperienced ones in the interpretation of arboreal forest,bamboo forest,special shrubbery and forest; higher resolution,more suitable time-phase remote sensing images and making full use of the forestry management information can increase the accuracy.
