中国林学会为了促进学术的繁荣,去年第四季度连续举办了两次学术报告会。一次是去年11月18日在林业科学研究院,由该院贾成章教授作了“利用太阳光能提高森林生长量”的学术报告。贾教授首先将太阳光的性能,太阳光与树种生物学特性的关系,林木对光线的要求等方面作了详细的论述;然后提出了利用太阳光能提高森林生长量的看法。他认为注意造林密度,加强抚育管理,改善林分环境是利用太阳光能提高森林生长量的重要途径。在森林经营上,加强太阳光能的研究,是一个重
In order to promote academic prosperity, the Chinese Society of Forestry has conducted two consecutive academic seminars in the fourth quarter of last year. Once on November 18 last year, in the Academy of Forestry, Professor Jia Chengzhang made a “use of solar energy can increase the amount of forest growth,” the academic report. Professor Jia firstly discussed in detail the properties of sunlight, the relationship between sunlight and the biological characteristics of trees, the requirements of trees for light, and then put forward the idea of using sunlight to improve forest growth. He believes that paying attention to the density of afforestation, strengthening tending and management, and improving the stand environment are important ways to utilize the sunlight to increase forest growth. In the forest management, to strengthen the research of solar energy is a heavy task
