摘要 以往的森林资源二类调查主要以地面调查为主,工作量重、流程繁琐,同时存在表、图、卡片分离的情况,调查期间会牵涉大量属性数据与空间数据,其中空间数据需要在纸质地形图采集,属性数据调查结果则以代码的形式进行保存,所以业内数据录入任务重,且在工作开展中出错率高,数据更新困难,与当前林业资源管理工作的开展不相符。在卫星技术、航空航天技术、遥感数字图像计算机解译技术持续发展背景下,以GIS、RS、GPS为主的3S集成技术因独特的高效快速、低耗科学等优势在森林资源规划设计调查领域中得到了大力应用,实现了传统工作模式不足的弥补,更能满足森林资源再生性、动态性与辽阔性等特征。在现代信息技术持续发展背景下,各类功能强大设备的出现更是为先进技术的应用提供了便利,将PDA与GIS技术联合开展森林资源规划设计调查成为了现下关注的焦点,可实现工作效率与质量的提升,促森林资源管理更加规范。故而本文结合工作实际致力于这方面展开探索,以供参考。 In the past,the second-class survey of forest resources was mainly based on ground surveys,with heavy workload and cumbersome procedures.At the same time,tables,graphs and cards were separated.During the survey,a large amount of attribute data and spatial data would be involved.The paper topographic map is collected,and the attribute data survey results are saved in the form of codes,so the data entry task in the industry is heavy,and the error rate in the work is high,and the data update is difficult,which is inconsistent with the current development of forestry resources management.Under the background of the continuous development of satellite technology,aerospace technology,and remote sensing digital image computer interpretation technology,3S integration technology based on GIS,RS,and GPS has been used in the field of forest resource planning,design and investigation due to its unique advantages of high efficiency,speed,and low-cost science.It has been vigorously applied in the traditional work mode,which can make up for the insufficiency of the traditional work mode,and can better meet the characteristics of the regeneration,dynamic and vastness of forest resources.Under the background of the continuous development of modern information technology,the emergence of various powerful equipment has provided convenience for the application of advanced technology.The joint PDA and GIS technology to carry out forest resource planning and design investigation has become the focus of attention now,which can achieve work efficiency With the improvement of quality,the management of forest resources will be more standardized.Therefore,this paper is devoted to exploring this aspect in combination with the actual work for reference.
