摘要
本文在明确速生丰产林概念的基础上,着重探讨了发展速生丰产林在我国林业建设中的地位,澄清了国内外不同林业发展战略思路(如接近自然的林业,林业分工论,新林业学说和生态林业等)与发展速生丰产林的关系.最后根据园内外发展速生丰产林(工业人工林)的经验和教训,指出今后我国速生丰产林的发展道路及应注意的问题.
Since 1958, development of fast growing and high yielding forests has beenadvocated in China. Due to great importance attached to it always by government, theestablishment of fast and growing and high yielding forests in China has undergone sever-al stages of development, with much useful experiences accumulated (of course,there are lessons to be learned, too). In the 'Outline of Greening Programme by Af-forestation from 1989-2000 in China', a definite task is assigned for establishing fast growing and high yielding timber forest bases. It is palnned that the area of fast growingand high yielding timber forests in the year 200 will be 7.89 million ha. The long rangeprogram is to establish such timber forests with an area of 20 million ha in 30 years. In1989, the State Council had the development of such timber forests included in the stateindustry policy. Now China is executing a program of establishing 6.76 million ha of fastgrowing and high yielding forests. Although some difficulties in allocation of forest landand investment intensity are encountered, yet we must manage to overcome the diffi-culties by improving the program of land utilization, upgrading the sulvicultural scienceand technology, perfecting the forest policy, making ful1 use of investment andstrengthening management so as to attain all the objectives in the above mentionedprogram. Henceforwards, special attention will be paid to the following aspects in de-veloping the fast growing and high yielding forests: (1) strengthening the research andpractice of directional culture of fast growing and high yielding forest, (2) stressingthe combination of short rotional fast growing and high yielding forests with the longrotational general timber forests, combination of general timber forests with rare spe-cies timber forests, and combination of thmber forests with multiple putpose forests.(3) carefully solving the problem of land required for establishing fast growing and highyielding forests and enlarging the capacity of investment, (4) utilizing new technologyto actively promote the forest productivity, (5) adhering to the principle of sustainedforest utilization.
