| 1 | Quantifying fire severity:a brief review and recommendations for improvement显示文摘Introduction:Quantifying fire severity is an important aspect of studying the response mechanism of terrestrial ecosystems to wildfire,and it is of great significance to fire ecology.In this paper we comprehensively introduce and compare the classification and quantification methods for fire severity;we discuss the development and application status of various methods,and we elucidate their existing problems.Results:1)According to features of the burned area,fire severity can be classified as light,moderate,and heavy.2)Using composite burn index(CBI)to quantify and record the fire severity.3)In quantifying fire severity with vegetation change,there are certain limitations and theoretical problems to be solved.4)Remote sensing could very well be an important means of measuring fire severity in the future,but there are still many problems that need to be solved before the remote sensing index can become a global fire severity indicator.Discussion and Conclusion:Only by clarifying the relationship between fire behavior,fire severity,time related variables and the pre-and post-fire ecosystem can the existing models be perfected or new,better fire severity measurement models be proposed for broad applications. | Dongdong Han Xueying Di Guang Yang Long Sun Yuetai Weng | 2021 | Ecosystem Health and Sustainability2021，7，1： | 1 |
