河口县林业局门前有两棵5年生柚木,树高16米,胸径25厘米。见过这两棵树的人,对如此这般迅速的生长量,无不感到惊讶和兴奋! 另据有关报道,新西兰靠80万公顷以辐射松为主的人工速生丰产林,每年生产木材850万立方米,占全国木材产量的95%,一变木材进口国为出口国。以上至少给了我们这样的启迪:营造速生丰产林不可忽视! 我省林业形势严峻,木材供需矛盾日渐突出,林木消耗量大大超过生长量。专家论证,这一情况如不迅速扭转,不用多少年,我省将滑下谷底,成为缺林少材的省份,生态环境将更加恶化。扭转形势的办法,无非是节流和开源。
Hekou County Forestry Bureau in front of two 5-year-old teak, tree height 16 meters, diameter 25 cm. According to reports, New Zealand’s 800,000 hectares of artificial fast-growing and high-yield forest dominated by Pinus radiata produces 8.5 million pieces of wood per year, according to reports from the two trees that saw such rapid growth. Cubic meter, accounting for 95% of the country’s timber production, a change of timber importing countries as exporting countries. Above at least give us such inspiration: to create fast growing forest can not be ignored! Forestry situation in our province is grim, increasingly prominent contradiction between supply and demand of timber, tree consumption greatly exceeded the growth. Experts argue that if this situation is not rapidly reversed and there is no need for years, the province will slip down and become a province that lacks forests and less timber and the ecological environment will worsen. The way to reverse the situation is nothing but throttling and open source.
