摘要
根据金殿林场森林资源档案数据,基于林场管理现状调查结果,客观分析了林场森林经营存在的问题和低产低效林产生的原因。结果表明:金殿林场低产低效林形成的原因主要是栽培树种选择不当、自然灾害发生频发,栽培树种配置不当、种植密度过大,政策体制限制较大、造林后经营管理措施不到位等。结合林场实际情况,提出调整林分密度、林分结构、实行补植补造和封山育林等改造措施,并对改造后的效果进行了预测,对改造中存在的困难进行了探讨,为今后林场科学经营国有森林资源提供重要指导意义。
According to the forest resources archives data of Jindian Forest Farm and the investigation results of forest farm management status,this paper objectively analyzed the problems existing in forest management and the causes of low-yield and low-efficiency forest.The results showed that the main reasons of low-yield and low-efficiency forest in Jindian Forest Farm were improper selection of tree species,frequent natural disasters,improper allocation of cultivated tree species,excessive planting density,restrictions on policy and system,and inadequate management measures after afforestation.Based on the actual situation of the forest farm,this paper put forward the improvement measures such as adjusting the stand density and stand structure,implementing supplementary planting and afforestation,closing the mountain for afforestation,as well as forecasted the effect after the improvement,and discussed the difficulties,so as to provide important guiding significance for the scientific management of state-owned forest resources in the future.
