同志们！中国林学会召开的这次“三北”防护林体系建设学术讨论会开得很好。国家科委、国家农委都很重视。国家农委张平化副主任在身体不大好的情况下特地抽出时间,到会上召开了一部分学者、专家的座谈会,听取大家的意见。他对这次学术讨论会是很满意的。我参加了几次大会和小会,听了几位专家的学术报告,看了一部分学术论文。我作为一个长期从事林业工作的人参加这次会是一次很好的学习机会,有些学术报告,是我过去没有听到过的,很受启发。我想,把大家这些思想、科学理论研究集中起来,对于搞好“三北”防护 Comrades! The symposium on the construction of the “Three Norths” shelterbelt system held by the Chinese Academy of Forestry went well. National Science and Technology Commission, National Agricultural Commission attach great importance. Zhang Xiaofa, deputy director of the National Agricultural Committee, specially took time out of his health and held a series of symposiums for scholars and experts to listen to everyone’s opinions. He is very satisfied with this symposium. I attended several conferences and meetings, listened to the academic reports of several experts and read some academic papers. My participation as a long-time forestry practitioner in this meeting is a great learning opportunity. Some academic reports, which I have not heard before, are very much inspired. I think we should pool the study of these ideas and scientific theories and do a good job in safeguarding the “Three Norths”
