我省自一九六○年以来,省林科所、山东农学院林学系、崂山林场、昆嵛山林场等单位对落叶松引种进行了大量的调查研究工作,取得丰富的成果。作者于1980年又进行了补充调查,增添了落叶松林群落结构等方面的材料。本文拟在上述研究成果的基础上,讨论一下几种落叶松与引种地区环境条件的关系。严格地说这篇材料是个集体的研究成果,由于作者水平所限,谬误不妥之处望大家批评指正。
Since 1960, the province has conducted a lot of investigations and studies on the introduction of larch in the departments of Forestry, Shandong Forestry College, Laoshan Forest Farm and Kunyu Mountain Forest Farm, and has achieved a lot of fruits. The author conducted a supplementary survey in 1980, adding materials to the community structure of larch forests. Based on the above research results, this paper discusses the relationship between several species of larch and the environmental conditions in the introduced area. Strictly speaking, this material is a collective research result. Due to the author’s limited level, mistakes are not good enough for everyone to criticize and correct.
