生态景观林林分改造工程建设理论与千岛湖区实践研究

马尾松和杉木林是受人为干扰下形成的次生的退化森林生态系统,群落结构不稳定,在千岛湖区选择针叶林阔叶化林分改造工程符合当地森林植被的自然演替规律,同时也被生产实践证明是有效的。本文回顾自1963年以来千岛湖区生态景观林林分改造工程的历程,对千岛湖区生态景观林林分改造工程建设指导思想、技术措施和建设成效进行了思考,同时提出千岛湖区生态景观林林分改造工程建设应加强对建设成效的监测,林分结构调整时应适当加大上层马尾松林的间伐强度,以及林分改造应与生物防火林带建设和森林病虫害的预防相结合等建议。

Research on construction theory of forest distribution alteration project of zoology sight forest and its practice in Qiandaohu district

Abstact: Horsetail pine and fir forest are hypo-growth degradation forest ecosystem formed by jamming.Its community structure is instable.The ongoing forest distribution alteration project of conifer broad-leafization in Qiandaohu district accords with the natural succession rule of local forest vegetation,meanwhile it is effective proven by practice.This passage reviewed the course of forest distribution alteration project of zoology sight forest in Qiandaohu district since 1963,reflected its guidance,technique measures and construction effect.Furthermore,put forward some suggestions such as,pay more attention to the supervision of construction effect,increase the space cut intensity of superstratum horsetail pine while forest distribution alteration,and forest distribution alteration should be combined with the construction of biology fireproofing forest belt and prevention of forest diseases and insect pests.
