摘要
当今木材消费结构发生了巨大变化,珍贵用材十分短缺,价格不断推高,然而我国现有珍贵用材资源存量很少,大量进口珍贵用材受到国际环保压力越来越大,必须立足国内培育珍贵用材,增加国家木材战略贮备。亚热带地区是我国林业生产最具活力的地区,因具有水热资源、种质资源、栽培技术和资金投入等优势,适宜大力发展珍贵用材林基地。亚热带地区优先发展的珍贵用材树种有香樟、闽楠、红豆树、福建柏、光皮桦、毛红椿、赤皮青冈、锥粟等,其基地发展模式主要有利用良好立地的新造林模式、基于次生林和生态公益林的改建模式及利用非规划林地的造林模式等,并提出了珍贵用材种质遗传保育和采种母树建立技术、主要珍贵用材树种新品种选育和种子丰产技术等急需解决的相关共性关键技术以及设立扶持、进行政策优惠和配套技术支持等保障条件。
Analysis on wood consumption structure and resources in China demonstrated shortage of precious timber and high price of wood With resources advantages of water, heat, germplasm, cultivation technique and capital, subtropical area has been the most vigorous forestry production area and suitable for establishing precious timber production bases. Recommended species are Cinnamomum camphora, Phoebe bournei, Ormosia hosiei, Fokienia hodginsii, Betula luminifera, Toona ciliata var. pubescens, Cyclobalanopsis gilva, Castanea henryi, etc. Models for the bases could be new afforestation, transformation from ecological forest and plantation around houses. Key techniques are needed to be solved with capital, policy and technical support conditions.
