上杭县林业发展潜力和可持续经营分析

Analysis of forestry development potentiality and sustainable management in Shanghang County

根据森林和林业资源消长的客观规律,遵循“法正林”概念和经营模式,运用林木生长和收获模型研究结果,采用动态比较的方法,分析上杭县的林业资源结构及其缺陷,研究并提出了分类指导的经营策略。分析表明,通过科学规划和经营,县域用材林林分在实施分类经营的前提下,可以适度缩减面积,保留生长(立地)类型良好的林分实施集约化经营,在10 a经营期内,可以增加2倍的采伐量,林木蓄积增长73%。同时可以促进竹林、经济林、薪材林等资源的增长,促进林区生产的多样化,实现林业生产、林区经济的协调、可持续发展。

Based on the objective laws of increase and decline of forests and forestry resources, and the ＂Normal Frost＂ concept and management model, using tree growth and harvest model, adopting the dynamic comparative method, this article analyses the forestry resources＇ structure and defects in Shanghang County, and studies and proposes specific guidance on the management strategy. The analysis shows that through scientific planning and management and classification management, timber forest area in the county can appropriately reduce and preserve forest stands of well growing （Site） type to implement intensive type management; the amount of logging can increase two times and stand volume can increase 73 % in the 10 year management. Meanwhile, the strategy can increase the resources of bamboo, economic forests, fuel - wood forests and other natural resources, promote forestry production diversification and realize forestry economy harmonious and sustainable development.
