在部分林区存在卫星信号弱或无信号的问题，这导致了卫星定位应用难以进行，为此笔者提出了一种将地面定位技术与卫星定位技术结合的应用方法。为证明地面定位技术在林区是否具有应用可行性，在高郁闭林分开展了地面无线定位信号强度随距离变化的规律以及树木遮挡对信号强度影响规律的试验。结果表明：无线信号在林区环境下与理想环境下的传播规律有相似性，可利用该规律修正理想传播模型。从理论角度证明了地面无线定位技术在高郁闭林分的适用性，可用于传播模型的建立和定位算法的研究。

In some forest, positioning by the satellites is different to be carried out due to weakness satellite signal or no signal. For this reason, an application method by combination of satellite positioning with ground positioning is proposed in this paper. To prove whether ground positioning technology is feasible in forest, the experiments to investigate the rela?tionship between wireless location signal strength variation and distance , and the effects of the trees blocking on the sig?nal strength experiments in the high canopy stands and carried out. The results show that the propagation of wireless sig?nal in the forest environment and the ideal environment are similar. This propagation characteristic can be used to revise the rules of the ideal propagation model. From the theoretical point of view, the application of the wireless location tech?nology in high?canopy forest stands is proved. This method provided a theoretical basis for the establishment of propaga?tion models and the study of positioning algorithm.
