遥感在森林资源调查中的应用动态综述

The review of remote sensing application to investigate forest resources

通过查阅并研究了1995年以来的国内外资料,综述了遥感应用于森林资源调查的沿革,重点介绍了“3S”技术在森林资源调查中应用现状,并提出未来遥感技术在进行森林调查方面应以精准化,数据网络化,新软件的研制、调查项目的多样化和减少调查的野外工作为主要研究方向。

The study summarizes the course of change and development of Remote Sensing application to forest resources ?investigation and the status quo of '3S'technique, which is the integration system of Remote Sensing, GIS and GPS and used widely in forest management, especially in forest resources?investigation. On the basis of review on progress and problems of Remote Sensing, suggestions on trends and contents of research in the future are put forward. They are generalized as follows: ①With the emergence of the high-resolution satellite data and the development of high spectrum technology ,the remote sensing expression of forest resources will become more accurate. ②Data of forest resources will form wide database net. ③Lot of software will be invented at rapider speed. ④The system will monitor and investigate from a single tree or forest resources to eco-environment. ⑤The quantity of field investigation work will be reduced further.
