摘要
中国东北地区有3700多万hm2森林资源,大部分为已严重退化的天然次生林。如何经营这些森林,是不予管理、任其退化,直至形成杂灌丛;还是"砍次留好",促进更新,逐步引向永久性森林?哈尔滨市林业局在山河、转山和丹青河3个直属林场,开展了以均衡发挥生态效益和经济效益为目地的经营实践,仅10余年时间3个林场就已获得了低投入、高产出的良好效果,走上了资源与经济良性循环的轨道。2009年9月,哈市林业局在中国林科院专家支持下,邀请德国森林经营专家Heinrich Spiecker教授和法国农业部高级顾问Dominique Danguy des Deserts先生考察了经营现场,并深入探讨了这些科学实验及其理论价值。
