摘 要:依据相关历史资料和森林资源调查数据,分析了东北林业大学帽儿山实验林场的红松原始林历史上的破坏和恢复现状。那时的原始林森林茂密,树木参天,公顷蓄积量约300 m3左右。这片原始林虽经历代政权的建立和更迭,但因人口稀少,生产力水平低下,开发利用有限等原因,减少了森林资源的消耗,自然保护了森林的存在与发展。但在1896~1945年间,遭到了沙皇俄国和日本军国主义的大势掠夺采伐破坏,原始林一扫而光,夷为荒山秃岭和残破林,每公顷蓄积仅为54.9 m3。为改变现状,迅速恢复森林资源,帽儿山林场于1958年以恢复生态学为理论依据,在全面调查的基础上引种红松种群,调整结构,形成针阔混交林,至今经过50年的恢复和改造,效果显著。In accordance with the relevant historical data and the restoration forest resources data, the stattts of Korean pine primitive forest before destruction in Maoershan experimental forest farm was analyzed. This forest was dense and the amount of growing stock was about 300 m3/ha, this primary forest experienced the regime establishment and change, but was protected and developed due to sparse population, low levels of productivity. In 1896 - 1945, the forest was destroyed by the predatory logging of Czar Russia and Japanese militarists. The primary, forest was wiped and razed to the barren ridge with only 54.9 m3/ha forest maintained. In order to change the status, and make the rapid recovery of forest resources, forest workers took the restoration ecology theory as the basis to make a comprehensive survey, adjust the structure, and introduce the Korean pine populations in 1958. After 50 years, the mixed needle-deciduous forests were established, the restoration effect was significant.
