Forest health theory is a new concept in the late 20th century to guide the operation and management of forest resources and forest pests governance a Forest Health Theory, China introduced in 2001, is intended as the construction of China's forestry guidance to improve the quality-oriented shift from quantity growth theory. In response to the presence of a single structure, stability, anti-human interference capacity is weak, not strong ecological service functions, high fire danger rating, low levels of biodiversity and pest hazards aggravated existing plantations of Beijing mountainous low level of productivity the main problems, 2006, the Beijing Municipal Bureau of landscaping project start \This test has been carried out, our existing plantations of Beijing mountainous comprehensive survey and data collection, to take a healthy business transformation measures based on the demonstration zone species plantations, after nearly three years, the test to obtain a preliminary results, major achievements and innovations are as follows: According to science, applicability, operability principles, combined with the natural features and value need to build a health assessment index system of the main species plantations of Beijing mountainous area of ??Beijing mountainous plantations. Selection of the average diameter at breast height, canopy density, the density of the tree layer, seedling regeneration density, the nine evaluation of the shrub species diversity Simpson index, the herbal species diversity Simpson index, the ratio of pest damage, fire danger rating, soil organic matter content, from productivity community structure, resistance (interference), four aspects of the soil conditions to evaluate the health of forest ecosystems. Negative oxygen ion concentration on forest microclimate and air monitoring, environmental and social benefits of forests included in the evaluation of forest health standards. Forest health diagnosis - forest functional orientation - forest health transformation - forest health monitoring forest health business model. Forest ecology, silviculture theory, recent natural operating theory as the theoretical basis, combined with the actual situation of the plantations of Beijing mountainous, a complete system of forest health management measures, including forest health stand structural adjustment (including zonal forest vegetation recovery and structural adjustment of low-quality stand health), monitoring and control of forest pests and diseases, forest fire management, soil health and management, biodiversity conservation.
