基于遥感的广东省桉树区域分布

The Research of Guangdong Eucalyptus Regional Distribution Based on Remote Sensing

以Landsat TM影像为信息源,遥感(RS)、地理信息系统(GIS)及统计分析等为手段,结合定位系统(GPS)实地调查验证,研究广东省桉树区域分布。结果表明:TM影像提取广东省桉树信息平均精度为92.78%;2011年广东省桉树林面积1350165 hm^2,占全省森林面积的13.3%;珠三角、粤西、粤东、粤北4个区域桉树面积分别为466687.03、375885.71、349579.92、158012.11 hm^2,分别占广东省桉树总面积的34.6%、27.8%、25.9%、11.7%。

Based on Remote Sensing Technology,GIS software,and other Data Analysis Method,this paper summarizes Guangdong Eucalyptus regional distribution combined with the GPS verification and using of Landsat TM data. The result shows： Average precision for information extraction of Guangdong Eucalyptus is 92. 78%. In 2011,Guangdong Eucalyptus is distributed in an area of about1350165 hm2,accounting for the forest area of 13. 3%. Pearl River Delta region,Western Guangdong,Eastern Guangdong and Northern Guangdong Eucalyptus are distributed apart in an area of about 466687. 03 hm2,375885. 71 hm2,349579. 92 hm2 and 158012. 11hm2,accounting for the forest area of 34. 6%,27. 8%,25. 9% and 11. 7% respectively.
