文章介绍了国际上围绕林业发展与自然保护之间所展开的辩论, 以及欧洲的整体林业观、美国的分类管理林业理论、日本建立森林生态系统保护区等。同时简述了菲律宾环境林业研究面对林区人口过密的难题和瑞典林业担心过分强调自然保护可能使其林产业在国际竞争中丧失竞争力等问题。德国林业界反对压缩木材生产; 美国林业界认为, 100年前平肖提倡的林业与自然保护就是一致的。台湾杨政川认为, 对森林单纯保护、优生性和劣生性变化的演化方向同时存在。

Some Thoughts on Contradition between Natural. Conservation and Forestry and Solution Proposed

The first part of this paper gives an account of the debate over the forest development and natural conservation with FAO and the periodical "Ecologist" as the representative arguers. The second part describes the overall view of forests in European countries, the theory of categorical management of forests in USA, and the establishment of conservation area of forest ecosystem in Japan, discussing on the coordination of nature conservation and forestry, and on casing the contradition. The paper also gives a brief account of the different problems in the Philippines and Sweden. The problem in the former country is excessive population density in the forest regions, while the latter is fearful of losing the competitive power in the international forest product market, if an overestimate of natural conservation is made. Circles of forestry in Germany arc against reduction of forest cutting in timber production. In USA a silviculturist said that one hundred years ago no contradition existed between forestry and natural conservation. Yang Zhichuan, a scholar in Taiwan province, maintains that in pure forest conservation both aristogenic and dysgenic changes may simultaneously occur in an evolutionary succession.
