目前林业现状和今后发展思路建国以来,党中央、国务院始终十分重视、密切关注林业建设,制订了正确的方针政策,采取了一系列有效措施,使我国林业在长期投入不足和面对人口增长、经济增长对森林资源巨大压力的情况下,仍然保持了较快的发展。一是人工造林保存面积居世界首位,实现了森林面积、蓄积量和覆盖率持续增长。全国人工造林保存面积达到7亿亩,约占世界人工林面积21亿亩的三分之一。目前,全国森林面积增加到23.8亿亩,森林蓄积量增加到112.7亿立方米,森林覆盖率由建国初期的8.6%提高到16.55%。二是防沙治沙取得重要成果,减缓了沙漠化扩展的趋势。特别是1978年三北防护林工程和1991年全国防沙治沙工程实
Since the establishment of the state of forestry and future development ideas, the CPC Central Committee and the State Council have always attached great importance to it, paid close attention to the forestry construction, formulated the correct guidelines and policies and adopted a series of effective measures to make forestry in our country face a long-term under-investment and population growth. Under the enormous pressure of economic growth on forest resources, rapid development still maintained. First, the area for artificial afforestation was the highest in the world, achieving a sustained increase in forest area, stock volume and coverage. The reserve of artificial afforestation nationwide reaches 700 million mu, accounting for about one-third of the world’s 2.1 billion mu of plantation forest. At present, the forest area in the country has increased to 2.38 billion mu and the forest volume has increased to 11.27 billion cubic meters. The forest coverage rate has been raised from 8.6% in the early days of the founding of New China to 16.55%. Second, achieving important results in preventing desertification and controlling desertification has slowed the trend of desertification expansion. In particular, in 1978 the Three North Shelterbelt project and the 1991 national anti-desertification project
