摘　　要：根据林业勘界测量技术规范参照工程测量规范制定的思想,给出了林业勘界测量中GPS平面控制网设计的原则,在此基础上,针对目前国内GPS平面控制网技术指标的确定没有给出具体计算公式的不足,提出了林业勘界测量中GPS平面控制网的主要技术指标与中间最弱点点位中误差的关系式,并使用工程测量规范中已知的相关技术参数对推导出的关系式进行了验证,最后推求了林业勘界测量技术规范中GPS平面控制网主要技术指标。According to the requirements of establishing forestry boundary surveying specifications based on engineering surveying code,design principles of GPS horizontal network in forestry boundary surveying is given in this paper.Aiming to the deficiency in determination of GPS horizontal network technical specifications by empirical value,relationship formulas between main technical specifications of GPS horizontal network and the errors of the weakest point involved in forestry boundary surveying is proposed.The formula is verified by the known technical engineering surveying specifications.Accordingly,technical specifications of the GPS horizontal network in forestry boundary surveying are deduced.
