摘要
金佛山方竹低效林具有普遍性,为提高竹林的经济效益和生态效益,文章根据相关标准和文献,提出了针对不同类型低效竹林的改造方案和技术措施.低效竹林改造应遵循自然修复和人工促进相结合的原则,兼顾近期效益与远期效益,因地制宜、因林施策,措施与技术科学合理、经济可行.无论是低效次生林还是低效人工林,间伐改造都是最主要的改造方式.在间伐改造过程中,应做到"砍老留幼、砍密留稀、砍小留大、砍弱留强、不砍林中空地的散生竹和林缘竹",使林中无病虫竹、无老弱竹、无枯立竹、无伤残竹、无高伐桩,对稀疏、老化竹林和林中空地应及时进行适当补植,尽快恢复成林.
Abstract
Low-yield Chimonobambusa utilis forest is common in many places.In order to improve its economic and ecological benefits,this paper proposes the plans and technical measures for improving the low-yield Ch.utilis forest of different types in accordance with relevant standards and literature.Low-yield bamboo forest improvement should follow the principle of combining natural restoration and artificial promotion,take into account both short-term and long-term benefits,and implement the scientifically rational and economically feasible technical measures tailored to local conditions and forest conditions.Thinning is the most important method to improve either the low-yield secondary forests or the low-yield artificial forests.In the process of thinning,it is imperative to achieve the goal of"cutting the old and keeping the young bamboo,cutting dense forest and keeping sparse forest,cutting small culms and keeping large culms,cutting weak and keeping strong,and maintaining the scattered bamboo in forest gaps and the bamboo at the forest edge",so to ensure there are no disease and pest infected bamboo,no old and weak bamboo,no withered standing bamboo,no damaged bamboo,and no high logging stakes in the forest.For sparse or aged bamboo forests and forest gaps,appropriate replanting should be carried out in a timely manner to restore them back into forest as soon as possible.
