森林健康评价方法综述

Review of forest health assessment methods

围绕森林健康评价方法,介绍了森林健康和森林健康评价的概念,在此基础上详细分析和评价了11种常见的森林健康评价方法的研究现状和特点,并从研究尺度和优缺点方面对各种评价方法进行了对比。结果表明:主成分分析法、层次分析法和综合指数评价法应用较多;评价方法不同,评价结果会有明显的差异;目前的评价主要针对森林健康现状的评价。在进行森林健康评价时,针对不同的森林类型应具体问题具体分析,选取合适的方法进行森林健康评价;评价方法不仅要着眼于现状,还应能够预测森林健康未来发展趋势。

This paper was focused on forest health assessment methods. First,the concept of forest health and forest health evaluation were introduced. Then,the concepts,research statuses,and advantages as well as disadvantages of 11 common forest health assessment methods were analyzed and evaluated. It was found that the principal component analysis,the analytic hierarchy process,and the comprehensive index evaluation method were used more frequently; with different evaluation methods,the evaluation results were significantly different; the current review is focused on the evaluation of the status. In a forest health assessment,it is suggested that the specific problems should be analyzed,and from these,the appropriate method for the forest health assessment should be selected. Evaluation methods should not only focus on the status,but also should be able to predict the future trends of forest health.
