摘　　要：本文主要从目标途径、生态系统途径和综合途径三个方面介绍了森林生态系统健康概念及其内涵 ,并分析了森林生态系统健康的评价指标体系及其标准。一般认为 ,不同的森林生态系统健康评估要根据具体的社会经济因素、生物物理环境、森林生态系统的自然属性选择合适的指标体系和标准。考虑到亚高山地区面临的主要任务是生物多样性保护和以水土保持为重点的生态功能恢复 ,因此采用生态系统学派 (强调生态功能 )为主进行健康诊断更具有实际意义 。Definition and connotation of forest ecosystem health were introduced from the aspects of the management objective approach, ecosystem approach, and integration approach. Furthermore, the evaluation indicators system and criteria of forest ecosystem health were analyzed. In a general way, social and economic facotrs, biophysical environment conditions, natural traits of forest ecosystem should be considered when evaluating forest ecosystem health status. With important biodiversity conservation, and water and soil conservation functions in West China, authors think it is essential to evaluate on ecosystem health for subalpine coniferous forests by adopting ecosystem approach concept emphasizing ecological function. Based on it we put forward the evaluation indicators and project of ecosystem health for subalpine coniferous forests.
