福建是我国南方多林省份之一,马尾松资源相当丰富,平均年产松材240万立方米,折蓄积量369万立方米。若以松根占蓄积量的15%计,每年就有松根55万立方米。这些松根过去基本上没有利用。随着对外开放,对内搞活经济政策的贯彻执行,林产工业有了较快的发展。加上目前我国森林资源短缺,能源亦比较紧张。因此,松根的综合利用,不仅有重要的现实意义,而且亦成为可能。但是,大规模挖掘马尾松树根,是否会破坏地表?引起的水土流失如何?则是令人关注的问题。水土流失是自然因素和人们各种生产活动
Fujian is one of the provinces in the southern China’s Duolin, Masson Pine resources are quite rich, with an average annual output of 2.4 million cubic meters of loose wood, folded volume of 3690000 cubic meters. If pine root accounts for 15% of the total volume, there are 550,000 cubic meters of pine root each year. These pine roots used to be essentially unused. With the opening up to the outside world and the implementation of an in-going revitalization of economic policies, the forestry industry has enjoyed rapid development. Coupled with the current shortage of forest resources in China, energy is also relatively tight. Therefore, the comprehensive utilization of pine needles not only has important practical significance, but also becomes possible. However, it is a matter of concern that large-scale excavation of Pinus massoniana roots can damage the soil surface and cause soil erosion. Soil erosion is a natural factor and people’s various production activities
