摘要
中国是一个森林覆盖率低、森林资源匮乏的国家。由于各种因素,森林生态系统有不同程度的退化。因此,研究中国森林生态系统健康状况,对保护现有的森林资源以及提高森林生态系统的质量具有重要作用。从森林生态系统的结构和功能的角度出发,选用复合结构功能指标评价方法。同时,在生态系统健康理论基础上,以活力(V)、组织结构(O)和恢复力(R)为评价指标,根据中美合作项目八达岭森林健康研究的数据,对八达岭地区森林生态系统的健康状况进行评价,建立一套相应的森林健康评价指标体系。
China is a country that owns lower forest overcast ratio and is short of forest resource. Owing to diversified factors, forest ecosystem has different degreed degeneration. Therefore the study of Chinese forest ecosystem health is very important to protect existing and improve the quality of forest resource.The complex fabric and function is chosen as the assessment of health indicator from the fabric and function of forest ecosystem. At the same time, on the basis of the biogeocenose theory, vigor （V）, organization （O）, and resilience （R） are taken as the indicators to evaluate large-scale forest ecosystem health. According to the data that studied by the item of Badaling Forest Health collaborated with America, a suit of estimate indicator system is established to appraise the status in Badaling.
