不久前,中国林学会召开学术会议,邀请从事植物生态、水土保持、沙漠化和地理地貌研究的专家、教授,以及战斗在“三北”(东北、华北、西北)地区林业战线上的科技工作者,讨论如何加快“三北”防护林体系建设问题。许多专家、教授一致呼吁:建设好“三北”防护林体系,必须做好总体工程规划。在总体工程规划的指导下,严格按照科学程序,把各方面的工作做好。 Not long ago, the Chinese Society of Forestry held an academic conference inviting experts and professors engaged in plant ecology, soil and water conservation, desertification and geomorphology as well as scientific and technological workers fighting on the forestry front in the “Three Norths” (northeast, north and northwest) , Discussing how to speed up the “Three Norths” shelterbelt system. Many experts and professors unanimously appealed: To build a “three north” shelterbelt system, we must do a good job in overall project planning. Under the guidance of overall project planning, we should strictly follow scientific procedures and do a good job in all aspects.
