贵州人工商品纯林树种结构调整存在的问题及对策

Solutions to Tree Species Adjustment of Artificial Commercial Pure Forest in Guizhou

为改变贵州省森林质量总体较差、人工纯林过多、树种单一、经济效益不高的局面,全面提升森林优质木材生产、木本粮油生产、蓄水保土、固碳释氧等综合能力,更好支撑经济社会发展,把人工商品纯林树种结构优化调整作为提高森林质量的突破口。本文根据多次实地调研结果,总结了人工商品纯林树种结构优化调整过程中存在的问题,并研究提出了相应对策,以期助推林业高质量发展。

A serious threat can often be found in the forest quality with artificial pure forests,single tree species,and economic benefits in Guizhou Province,China.It is a high demand to fully improve the comprehensive capacity of forest for the better economic and social development,including the high-quality wood production,woody grain and oil production,water storage and soil conservation,carbon fixation and oxygen release.Among them,the forest quality can be expected to optimize and adjust the population structure of tree species in the artificial commercial pure forest.In this study,a series of field investigations were implemented to clarify some existing challenges in the optimization and adjustment of the tree species structure in the artificial commercial pure forests.Some recommendations were then proposed to promote the high-quality development of forestry.
