摘　　要：为了提高森林资源调查的精度和效率,提出1种利用北斗卫星导航系统(BDS)及全球定位系统(GPS)双星座定位技术进行森林资源调查的方法:以北京市海淀区东升八家郊野公园为研究区,分析比较BDS/GPS双星座数据较之于单星座数据在提高精度上的优势;然后使用Visual Studio2010开发森林资源调查后处理软件,研究如何提高森林资源调查管理效率。结果表明:BDS/GPS双星座定位数据的绝对误差大多不超过5 m,实际误差在X、Y、Z方向上均小于单BDS和GPS的误差;双星座定位技术可以提供较高精度的森林资源调查结果,满足相关技术规定的精度要求,结合森林资源调查后处理软件,可提升森林资源信息化水平,为林业卫星导航提供参考。In order to improve the accuracy and efficiency of the forest resources survey,the paper proposed a survey method using BeiDou navigation satellite System(BDS)and Global Positioning System(GPS)double constellation positioning technology:by taking Dongsheng Bajia country park in Haidian District of Beijing as the study area,the advantages of BDS/GPS double constellation data in improving the survey accuracy were compared with single constellation data;and Visual Studio 2010 was used to develop the post-processing software of forest resources survey for studying on improving the management efficiency of the survey.Results showed that:the absolute error of the BDS/GPS double constellation positioning data could be mostly less than 5 m,and the actual errors in the X,Y,and Z directions would be all smaller than those of the single constellation data,indicating that double constellation positioning technology could meet the precision requirements of related technical regulations with high-precise survey achievements,and combining with the proposed post-processing software,it could provide a reference for enhancing the informationization of forest resources and forestry satellite navigation.
