摘　　要：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。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 general problems, such as the tree species structure was single, the growth speed was slow. the ecological protective function was low, and the economic benefit was bad. The low-- yielding and inefficient Pinus massoniana 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.
