GPS eTrex在森林资源监测中的应用

Application of GPS eTrex on Forest Resource Monitoring

概述了GPSeTrex手持式全球卫星定位仪的工作原理、性能、坐标系统的转换及校正。详述其在森林资源调查、规划及监测中的应用。利用 2 0 0 2年度云南省森林资源连续清查的成果 ,对采用GPSeTrex全球卫星定位仪与常规“连清”方法进行对比分析。提出了今后森林资源监测工作的建议。

The principles, functions as well as the conversion and correction of coordinate system of GPS eTrex were summarized in this paper. The application of GPS eTrex on continuous forest inventory, forest management inventory, supervision of reforestation achievement, implementation of forest quota system, and inventory of occupation of woodland and so on, was illustrated. By using the results of continuous forest inventory from both routine approach and GPS eTrex, the comparative analyzed was carried out, and some suggestions were proposed for the future work of forest resource monitoring.
