By using statistics methods, a way of estimating cousume amount of forest resources was presented which, is suited to the new situation in the open wood-market in the Southern China's collective forest areas. And its reliable degree was tested and economic significance evaluated on the basis of on the spot research in Saxian county, Fujian province. 本文主要通过应用统计学的有关知识,提出适应南方集体林区木材市场开放新格局的一种估测林木资源消耗量的方法;并将这种方法在沙县进行了实地验证;分析了其可靠程度与经济意义。 Circulation of wood in Japan includes circulation of native log and that ofimported log, circulation of homc-made wood products and of products made fromforeign wood, and circulation of processed wood.

Circulation of wood in Japan includes circulation of native log and that ofimported log, circulation of homc-made wood products and of products made fromforeign wood, and circulation of processed wood. An introduction is made in this paperto the status, traits, future trends and resulting influence on Japanese forestry underdifferent modes of wood circulation. The circulation of mative wood in Japan was com-pleted directly between producers and customers in the past. Now it has evolved into acomplex process: forest owners ?log producers ?log market ?wood consumers. Thisis an inevitable result from specialization of production and circulation. Since 1960s,much more wood was imported into Japan. Foreign wood shares an increasing propor-tion in the total of wood supply. Compared to circulation of native logs in Japan thereare less intermediate links in the chain of circulation of foreign logs. The feature of circu-lation of home-made wood products in Japan is that the proportion of direct sales is lessthan in former times, and the proportion of sales on wood product market and throughwood brokers incresses. The feature of circulation of products made from foreign woodis sales through wood brokers, supplemented by sales on wood product market. Thecirculation of processed wood implics that wood is improted from foreign country and isprocessed in Japan. In recent years, due to change of international wood market,proportion of log in the total of imported wood decreases. Instead, wood productsand processed materials are imported. This is a real problem the Japanese wood pro-cessing industry is confronted with. 日本木材流通的特点是:国产材的开发利用与进口外材并举。60年代后,进口材在总需材量中所占比重越来越大;原木在总进口材中所占比重越来越小。这是当前日本林业生产、木材加工和流通领域所面临的新问题。 Describes the economical consideration of the best efficiency for forest production, and forest economical maturity. Decisive method of forest economical maturity based on the theory and method of productive functional, analysis sequential forest price and wood market price were discussed. 根据生产函数分析的理论和方法,分别以序列林价和现行木材市场销售价为基础,讨论了确定森林经济成熟龄的方法。
