从CAB林业文摘看世界林业科学的发展

Judging world Tendency of Forestry Scientific Research by CAB Forestryabstracts.

通过对ＣＡＢ林业文摘的前期（１９７８～１９８６年）和后期（１９８７～１９９５年）报道的林业文献对比分析，结果表明世界林业文献量在前后期都居前１０名的国家是美国、印度、德国、加拿大、英国、日本、前苏联、澳大利亚、中国和法国，反映出世界主要林业科研国家具有连续性和稳定性的特征。从研究内容看，森林生物学和森林培育学的主题在前后期都居领先地位；对森林昆虫和森林生态学主题研究的重视程度后期比前期有明显提高；而树木气象学等几个主题文献量前后期都处于最后几位。中国林业科研文献量增加的速度居世界前矛，研究重点在前后期都以森林生物、森林昆虫和森林培育为主攻目标，在后期对森林生态和遗传育种等主题的研究也已有了足够的重视。

According to comparing and analyzing the forestry literature repo rted by CAB Forest ry Abstracts in previous period(1978～1986) and later period(1987～1985),it was conclutcd that the first tea countries were chang-less in the two periods,i.e.USA,India,Germany,Canada,UK,Japan,former USSR,Australia,China and France, which reflected that the main forestry scientific research countries were of Succession and stability,In research sub-stance, the subjects on forest biology and forest cultivation were the leading ones in the two periods, and researches on the subjects of forest entomology and forest ecology were taken much more seriously in the later period than before,But the other subjects,such as forest meteorology,were standed ch angeless ih the later period,The speed incressing literature amout of foreat scientific research in China was much more quickly than tbe most of othercountries,Forest biology, forest entomology and forest cultivation were paied more attention to in china in the two periods,and forest ecology, genn etics and breeding were focused in the later period.
