Based on field investigation, guided by the principle of maneuverability, sciences, comparability, acceptability, this paper took health assessment of Badaling forest center about plant species diversity, construction of forest community, canopy density, cover of shrub community, age structure, stand, soil erosion, plant diseases and insects pests and measured for ordination by adopting the complex structure and function indicator method, which set off 4 ordination for forest ecosystem. Health forests of small scale are the structure of more layer and age, mixed forest, better layer of shrub and grass, better biodiversity and productivity, which are better stability, anti-interfere and vigor . This is a kind of better structure of forest health community which offers the scientific theory of forest health management for Badaling forest center.
