乌兰布和沙漠高分辨率遥感影像梭梭林解译方法探讨

利用ALOS、SPOT5高分辨率遥感影像,结合野外调查,完成了乌兰布和沙漠研究区遥感影像信息的目视解译及植被制图,并结合GPS野外样点进行精度评价,解译精度为93.3%,梭梭林面积为165 410.62 hm²,占乌兰布和沙漠地区总土地面积的17.27%。最后,对乌兰布和沙漠遥感影像梭梭林解译的方法进行了探讨。

Discussion on the Method of High-resolution Remote Sensor Data Interpretation of Haloxylon Ammodendron in Ulan Buh Desert

According to ALOS,SPOT5 high\|resolution remote sensing image analysis and field investigation,we have completed the remote sensing information visual extraction and vegetation mapping in Ulan Buh Desert,while combined with GPS field records,we have finished accuracy evaluation,the result was satisfactory.The accuracy of visual interpretation was about 93.3%,the area Haloxylon Ammodendron was 165 410.62 hm²,accounting for Ulan Buh Desert 17.27% of total land area.Meanwhile,methods of remote sensing image interpretation,which were suitable for Haloxylon forest in the Ulan Buh Desert ,were also discussed.
