摘  要：
研究了人工抚育 6年后油松林的生长状况、群落组成和结构 .结果表明 ,不同人工抚育措施的油松林平均胸径、树高、冠幅均有极显著差异 (P <0 0 1) ,采取抚育措施的两个样地间的油松胸径和冠幅差异均达到显著水平 ,其中既打枝又间伐的油松林的胸径 (7 8± 0 2 9cm)、树高 (5 5± 0 0 9m)和平均冠幅(2 4 9± 7 2 4cm)最大 ,未打枝和间伐的油松林最小 ;随着人工抚育措施加强 ,单株油松的平均新叶、老叶和枝的生物量逐渐增加 ,达到极显著水平 (P <0 0 1) ;在不同抚育措施下 ,既打枝又间伐的油松林地上生物量最大 (44 0t·hm-2 )、未打枝和间伐油松林地上生物量最小 (14 9t·hm-2 ) ;油松新叶和老叶长度的差异性显著 ;油松的比叶面积在生长初期 (5月和 6月 )和末期 (9月 )差异性显著 ;人工抚育措施增加了林下植被的种类数量和盖度 .

摘  要：
The investigation on the growth status,community composition,and structural characteristics of Pinus tabulaeformis forest artificially tended for six years showed that there were significant differences in the average DBH,height,and crown size of the forest among the treatments DA (trimming without intermediate cutting),FA (trimming and intermediate cutting) and CK (without trending).Treatment FA had the highest values of average DBH (7.8±0.29 cm),height (5.5±0.09 m) and crown size (249±7.24 cm),while the CK had the lowest ones.The average biomass of new leaf (1 year old),old leaf (2 or more year old),and branch per tree increased significantly ( P <0 01) with enhancing tending treatments.The aboveground biomass of treatment FA was the biggest (44 0 t·hm -2 ),and that of CK was the smallest(14.9 t·hm -2 ).The leaf length and SLA at the early and terminal stages of development (May,June and September) had significant difference among the treatments,and the amount of community composition and the cover degree of undergrowth plants increased evidently under artificial tending treatments.
