该文从理论基础到实践、从技术进步到效益评估、从林业调查发展史与中国现状相结合 ,全面地论述新体系建立的必要及技术支撑、运行模式和需要改进的问题 .2 0世纪 70年代末 ,遥感技术被应用于中国的森林资源调查工作 ,特别是森林蓄积量的估测 .曾研究了比值项的作用 ,确定用定量因子和定性因子联合估测森林蓄积量多元估计方程的形式 ,以及在中国不同气候带的应用 .在对精度和费用进行了细致的分析后指出 :遥感调查方法比传统方法节约经费 1 3～ 1 2 .近年来 ,作者在上述研究的基础上 ,用近代统计学和非参数方法进行了新的探索和深入研究 .解决了一些在林业资源调查中应用遥感技术的重要问题 ,并引入地理信息系统 (GIS)和全球定位系统 (GPS) ,为建立以遥感为主要技术手段的新的森林资源估测体系提供有力支持 This article from the theoretical basis to practice, from technological progress to benefit evaluation, from the history of forestry investigation and the status quo of China combined to fully discuss the necessary and technical support for the new system, mode of operation and the need to improve the problem .0 century 70 At the end of the decade, remote sensing technology was applied to forest resources survey in China, especially the estimation of forest stock volume.It studied the role of ratio items and determined the form of multivariate estimation equation of forest stock volume estimated by quantitative factor and qualitative factor , As well as its application in different climatic zones in China.After careful analysis of accuracy and cost, it is pointed out that remote sensing survey method can save 13% to 12% of the traditional method.In recent years, on the basis of the above research, Statistical and non-parametric methods, and solved some important problems in the application of remote sensing technology in forestry resources survey, and introduced the geographic information system (GIS) and global positioning system (GPS) As the main technical means of new forest resources estimation system to provide strong support
