湖北省马尾松低产林成因与改造对策

据统计,我省马尾松林面积和蓄积分别占全省的37.8%、40.6%,均居全省之首。然而不容忽视的是,我省马尾松林普遍存在着林种结构单一、生长速度缓慢、生态防护功能低下、经济效益差等突出问题。大量低产、低效马尾松林的存在极大地浪费了我省有限的林地资源,严重阻碍了我省建设林业资源大省和产业强省的目标实现。为此,笔者就我省马尾松低产林形成原因及其改良措施谈几点看法,仅供参考。

Genesis and Countermeasure of Pinus massoniana Lamb. Low-yield Forest in Hubei Province

Statistics suggested that the area and volume proportion of Pinus massoniana Lamb.to Hubei Province were 37.8% and 40.6%,which were both the highest in all tree species.But there were some gen- eral problems,such as the tree species structure was single,the growth speed was slow,the ecological protec- tive function was low,and the economic benefit was bad.The low-yielding and inefficient Pinus massoni- ana Lamb.forest wasted the limited forestland resource seriously,and it prevented us becoming the forest resource and industry prosperous province.Therefore,the authors analyzed the formation cause of low- yield forest,and gave the view on improving measures,for reference only.
