Describes the natural regeneration of various types of pinus armandii forests in Qinling mountain forest region. Natural regeneration at the mountain foot and the stream side was much better than that of the mixed forests with grasses or shurbs. Regeneration of the forests a.t cliffs or the forest mixed with bamboos was underdeveloped. The regenerated saplings and seedlings on cleared areas were complicated with certain proportion of. non-objective tree speices. The relationships between natural regeneration and cutting and skidding system, canopy closure, litter layer thickness, the depth of soil layers, topography, understorey or ground vegetation were analyzed. Considerations for the management and utilization of the forests were also suggested.

This article describes a modern forest management system-management byobjective which has been adopted in the Western European countries such as Austria andGermany. Its characteristics are: objective trees are selected for culture in the first thin-ning; stand improvement and intermediate felling in all management activities are de-termined in accordance with the growth and development of the objective trees and theimpact of surrounding trees on them during the growing period. The main steps involvedin the system are: objective is set on basis of the requirement and specification or woodproduct and the bioiogical characteristies of tree growth; suitable stands in whichenough objective trees can be found are selected.Objective trees are chosen on the follow-ing principles: trees are predominant in the stands with vigorous growth and intactstem, without big branches and are evenly distributed in the stands with a H / D valuebelow 80. The principal mode of intermeidate felling is thinning by interpretation.
