Ecosystem health assessment is one of the main researches and urgent tasks of ecosystem science in 21st century. An operational definition on ecosystem health and an all-sided, simple, easy operational and standard index system, which are the foundation of assessment on ecosystem health, are necessary in obtaining a simple and applicable assessment theory and method of ecosystem health. Taking the Korean pine and broadleaved mixed forest ecosystem as an example, an originally creative idea on ecosystem health was put forward in this paper based on the idea of mode ecosystem set and the idea of forest ecosystem health, together with its assessment. This creative idea can help understand what ecosystem health is. Finally, a formula was deduced based on a new effective health assessment method--health distance (HD), which is the first time to be brought forward in China. At the same time, aiming at it's characteristics by status understanding and material health questions, a health index system of Korean pine and broadleaved mixed forest ecosystem was put forward in this paper, which is a compound ecosystem based on the compound properties of nature, economy and society. It is concrete enough to measure sub-index, so it is the foundation to assess ecosystem health of Korean pine and broadleaved mixed forest in next researches.
生态系统健康评估是21世纪生态系统科学的主要研究内容和紧迫任务之一。在获取简单实用的生态系统健康评估理论与方法时，需要一个关于生态系统健康的操作性定义以及一个全面、简单、易于操作且标准化的指标体系，这是生态系统健康评估的基础。以红松阔叶混交林生态系统为例，本文基于模式生态系统集的思想和森林生态系统健康的理念，提出了一种关于生态系统健康的原创性思路及其评估方法。这种创新思路有助于理解生态系统健康的内涵。最后，基于一种新的有效健康评估方法——健康距离（HD）推导出一个公式，这是该方法首次在中国被提出。同时，针对红松阔叶混交林生态系统的现状及物质健康问题，提出了其健康指标体系，该生态系统是基于自然、经济和社会复合属性的复合生态系统。该体系具体到可测量子指标，是后续研究中评估红松阔叶混交林生态系统健康的基础。
