中文摘要：

在理论分析手持型GPS接收机面积测量原理的基础上,对9个不同大小地块在不同时段、不同干扰条件下实际面积测量的精度进行分析,详细论证了手持型GPS接收机完全能够满足退耕还林、造林地验收、小班面积测量等精度的需要,可广泛应用于森林资源调查.

英文摘要：

Based on theoretical analysis of area measurement principle,the practical area survey precision of nine different sized plots in different period and under different interfered conditions are analyzed by using handheld GPS receiver.It is demonstrated in detail handheld GPS can fully meet the precision needs of returning farmland to forest,inspection and acceptance of afforestation land,area survey of sub-compartment,etc.It can be widely used in forest resource inventory.
