云南的热带地区,一方面森林被破坏,出现大量荒山荒地,需要恢复森林覆被以维持生态平衡;一方面具有优越的水热条件和丰富的树种资源,正是生产特有速生珍贵林木的理想场所。热带营林因此应运而生,但这一事业刚刚开始,缺乏各种基本资料。我们从一九七四年开始进行云南热区的优良速生珍贵用材树种调查,接触到热带地区的营林问题,现将有关资料整理出来,并就营林区划及树种选择提出初步意见,以供讨论、参考。
In the tropical areas of Yunnan, on the one hand the forests are destroyed and there are a lot of barren hills and wilderness, and forest cover needs to be restored to maintain the ecological balance. On the one hand, it has excellent hydrothermal conditions and rich tree species resources, and is an ideal place for producing valuable fast-growing rare trees . As a result, tropical forestry came into being, but this undertaking has just begun, lacking all kinds of basic information. Since 1974, we conducted a survey of excellent and quick-growing precious timber species in the hot area of Yunnan Province and contacted the management of the afforestation in the tropical areas. We have now sorted out the relevant information and put forward our preliminary opinions on the afforestation and tree species selection for Discussion, reference.
