The Inventory Method and Result Analysis of Forest Hazard Inventory by Using Color Infrared Aerial Photos
彩红外航空像片应用于森林灾害调查的方法与结果分析

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.
