摘 要
在当前的林业生产中,使用传统的数据采集方式已经不能符合林业数据信息化,数字化的管理要求。3S技术把森林资源的调查与监测推向了现代高新科技的新时代, 从而使森林资源调查与监测范围扩大、周期缩短,精度提高、现势性增强、工作量减小,进入数字化、实时化、自动化、动态化、集成化、智能化的新时代。以移动GIS为平台的野外森林资源信息采集技术的发展,实现了林业资源调查与管理工作中的从野外数据调查采集到室内专业化数据处理,以及对森林资源数据的信息化管理的三个不同工作阶段的信息化管理掌上森林资源调查系Qtree的采集方式和功能做了解,分析该软件在资源数据采集上的不够完善之处,然后深入研究FORESTAR Mobile 系统的功能结构设计,明确了基于移动GIS的森林资源采集系统其对我国“数字林业”的发展的推动作用。

Along with the development in the construction of “digital forestry”, the traditional way of data acquisition has not been able to satisfy the requests of data processing .A new member named 3S was introduced to resolve the problem. It has created a new period with high-tech for the works in forestry resources survey and supervise, greatly enrich the scope,shorted the time, improved the resolution of the data, reduced the human works, enhanced the timeliness. Since then, forestry resource survey and supervise work stuffs came into the world with dynamic, digital, intelligent, automatic, integrated resolution. The acquisition technology plated on Mobile GIS has realized the forestry information-based management in data acquisition, processing and management, mended the construction of the digital forestry’s step greatly.
The article is mainly talked about the research on the characters of forestry resource and the technology in data acquisition works, described the ways XingYuanTong Mobile and Qtree Mobile provided in data acquisition, found out the certain limitations they got ,then laid great stress on stating the way FORESTAR Mobile system supplied in dealing with the limitation problems, analyzed the benefit Mobile GIS brought in the forestry works, confirmed the importance it played in the forestry re
