云南松林是滇中高原重要的森林类型,但因过度采伐、植物入侵及病虫为害等出现了不同程度退化。我们通过试验,总结出了退化云南松林混阔控紫的恢复技术模式。该模式核心是针对高密度云南松林开展抚育间伐术,中低密度云南松林开展封山育林,对恢复过程中出现入侵林分的紫茎泽兰实施人工防除技术,从而把退化云南松林逐步导向针阔混交复层异龄林。
Pinus yunnanensis is an important forest type in the Central Yunnan Plateau, but degenerated to some extent due to over-harvesting, plant invasion and pests and diseases. Through experiments, we conclude the technical model for the restoration of broad-leaved purple in Pinus yunnanensis forest. The core of this model is to carry out tending thinning for high-density pine forests in Yunnan Province, and afforestation in middle-low density pine forests in Yunnan Province. Artificial prevention and control techniques are applied to the invasion of Eupatorium adenophorum during the restoration process, Stratum anaerobic forest.
