This article introduce procedures and methods of using large scale (1:5,000) color infrared transparency to inventory the damaged forests by an example in West Germany; summarize the interpretation keys of identifying tree species and injury status of forest trees on color infrared aerial photos; analyze the stress degree to forest health conditions by factors such as species, ages and elevation. Finally, precision of the inventory are listed. Results have already demonstrated that methods of applying color infrared photos to assess the injury degree to forest trees caused by air pollution, disease and insects, natural disaster can rapidly provide information with higher precision which is needed during the planning process of making sound forest management plans.

Abstract Airborne videography is emerging as a remote sensing tool available to re-source management and assessment. An airborne video system, provided by USDAForest Service,consists of two major modules-an airborne video image acquisition sys-tem including the global positioning system and a video image processing system, to beused in China for monitoring and mapping two important Chinese pests,the pine cater-pillar Dendrolimus punctatus and the pine nematode Bursaphelenchus xylophilus. Videooffice sketch mapping is the preferred method for analyzing aerial video data , while com-puter screen sketch mapping should become the most efficient and effective technique af-ter the development on automated digital mosaicking. The automated damage area distinction and damage degree classification could be solved when using modern color-in-frared video cameras.This paper introduced the status of airborne video system and theapplications in foreign countries and China on the forest health management, and discussed the characteristics of the system and the tendency to improve.

This paper demonstrates a simple method of monitoring stand needle biomass and its changes in masson pine forest with Landsat TM data. The forest health situation can be known by comparing monitored satellite data with basic data obtained by forest resources investigation. According to the macroscopically monitored results, an experienced forester can predict the development trend of damage and present corresponding protecting strategy. Thus, the task of macroscopic monitoring and predicting forest damages caused by pests can be realized.
