摘　　要：在对胆扎林区抚育间伐经营活动研究的基础上,编制出云杉胸径定量间伐标准表,说明轻度间伐可调整林分密度、促进林分生长、改善林分生态因子,从而获得良好的经营效果和生态效益.The quantitative thinning standard set by diameter at breast height for Picea asperata is compiled according to study on management activities of thinning in Danzha forest district. It is demonstrated by the experiments that satisfactory management effect and ecological benefits can be obtained by appropriate light thinning to regulate forest density, improve forest growth and to ameliorate ecological factors inside the forest stands.
