航测在南方森林采伐中的应用

<正>一 引言 森林采伐,首先要进行生产工艺和工程设计,由于这项工作大部分在野外进行,作业范围大,特别是南方山地林区地形复杂,导致外业工作量大,效率低。因此,我们尝试利用航测技术来解决。利用它把大量的外业工作移至室内进行,节省人力、物力,并能提高工作效率和工艺设计精度。同时航片上所反映的信息很多,借助一定的仪器设备进行立体观察,分析,测量和比较,这样在进行生产工艺和工程设计时,便于综合考虑多种影响因素,从而保证所选择的工艺方案经济上合理,技术上先进可行。由此可见利用航测技术进行森林采伐工艺设计,对改善作业条件,提高劳动效率,作业精度,以及提高林业现代化水平都具有重要意义。为此,我们就应用航测技术进行工艺设计做了些试验,探讨其可行性及适用程度。然而本文仅是最初的探讨,有些问题还有待于讲一步解决与完善。

THE APPLICATION OF AERIAL SURVEY TO THE FOREST CUTTING IN THE SOUTH

Before cutting down a forest, the production technology and project program need to be drawn out,which takes large amount of work and leads to inefficiency. It is suggested in this paper that aerial photo technique be adopted insead to improve the traditional measures,moving the field work into office so as to save manpower and material resources and raise efficiency. Moreover, with the aid of apparatus we can make stereoscopic observation and analysis, which ensures that the techn-ological program worked out will be resonable and feasible both in economy and technology. There remains some probles in this new method, however, which needs furt-> her investigalion and study to become an effective one.
