速生丰产林是集约经营的人工林。林分的生长、发育除了受自然条件的制约以外,还要受人们经济活动的强烈影响。完全受自然条件限制,而不受人为控制的不叫速生丰产林。 我省营造速生丰产林已有二十多年的历史。但是从七十年代后期开始,速生丰产林的营造技术和管理措施才逐步有新的突破。虽然我省早在1958年就提出营造速生丰产林,但从1976年才开始真正的进行这项工作,1979年才推广开来,营造的面积迅速扩大。目前,可以说是处于方兴未艾的阶段。据估计,全省现有速生丰产林的面积约在五十万亩左右。但从现在的情况看,营造速生丰产林的标准不统一,质量上不去。为了进一步提高我省速生丰产
Fast growing forest is intensive management of plantation. In addition to being restricted by natural conditions, the growth and development of the forest stand are strongly influenced by the economic activities of the people. Fully limited by the natural conditions, but not under the control of people called fast-growing high yield forest. My province to create fast-growing high-yield forest has more than 20 years of history. However, since the late 1970s, new technologies have been gradually introduced to create technologies and management measures for fast-growing and high-yield forests. Although our province proposed to build fast-growing and high-yield forests as far back as 1958, this work was not started until 1976, and was popularized in 1979. The area thus created has rapidly expanded. At present, it can be said is in the ascendant phase. It is estimated that the existing area of fast-growing and high-yield forests in the province is about 500,000 mu. However, from the current situation, the standards for creating fast-growing and high-yield forests are not uniform and the quality is not improved. In order to further enhance the province’s fast-growing and high yield
