油松(Pinus tabulaeformis Carr.)占辽宁人工林总面积的30%以上,是辽宁重要后备森林资源。我们于1973—1983年在油松林主要分布区设立了13个定位观测点,按类型区、地位、质量、年龄和初植密度,建立69个区组,314块抚育间伐试验小区,研究油松林间伐效果、间伐技术和经营图表的编制,并从掌握油松林生长与年龄、立木密度之间的数量关系入手,探索以“三元控制”最佳密度管理为核心的间伐技术理论.

The productivity of various forest zones and the influential factors on its production were studied. The result showed that there are significant differences among these forest zones, of which the highest production occurs in the tropical mountain rain forest while the evergreen monsoon forest is lower and the least production appears in the dwarf mountainous woodland. No significant difference of production was detected between forest types within the same forest zone, where the tree form has no great variance...

The productivity of various forest zones and the influential factors on its production were studied. The result showed that there are significant differences among these forest zones, of which the highest production occurs in the tropical mountain rain forest while the evergreen monsoon forest is lower and the least production appears in the dwarf mountainous woodland. No significant difference of production was detected between forest types within the same forest zone, where the tree form has no great variance as the natural forest has reached its mature stage. Therefore the major influential factors on the total production are mean diameter, tree height and density of stands.It is owing to younger age of the secondary forest stand so that the production at present is low but it will obtain high production if better care of management should be taken, its wide range of area is a resource of reserve forest which should not be neglected. In order to promote its mature earlier intensive management must be taken.

本文探讨了不同森林带林分的生产力及影响产量的因素。研究结果表明,不同森林带林分生产力差异显著,热带山地雨林产量最高,常绿季雨林稍次,山顶苔藓矮林最低;同带间不同森林类型差异不显著。由于尖峰岭的天然林已达成熟阶段,干形变化不大,因此,影响林分总产量的主要因素是林分的平均直径、树高和密度。次生林目前尚处于中幼龄阶段,产量较低,如能加强管理,可获高产。大面积的次生林是一不可忽视的后备资源,应加强管育,促使早日成材。

The history and present situation of genetic resources conserva-tion of world forest, as well as appropriate tactics of China is discussed.20 million ha. of natural reserves are delineated in China, which acco-unts for 2.08% of China's territory. The natural genes of 354 importanttree species and vegetation species are under protection, and more than 30rare and valuable tree species were put under national protection of classone to three. 13 provenances and excellent provenances, such as Chinesefir (Cunninghamia R.Br.) and Masson pine (P. massoniana) were recognizedand related communities were in situ or ex situ conserved. Besides, pro-venances or stands of 18 tree species were partially conserved, and thecontracted reserve forests amount to 34 thousand ha. 26000 phenotypes we-re selected according to phormological characters. The conserved hybridsof poplar and other broadleaves,tneir plus trees and clones genes amountto 6000, while those of introduced eucalypts, Loblolly pine (P. taeda),Slash pine (P. elliottii) are more than 400. The conservation tactics ofChina forest genetic resources is systematic administration, effective con-servation, reasonable utilization and abundant development.

综述了世界森林遗传资源保存的历史和现状,作者认为中国森林遗传资源的保存策略应为系统管理、有效保存、合理利用、丰富发展。
