Studies on the current state of forest management and genetic resources of tree plant in Sakhalin.

前苏联远东地区拥有大量的森林资源。该地区的趋势影响了世界市场上可获得的森林产品，特别是日本，该地区的木材开采可能造成严重的环境问题。因此，需要对远东的森林和林业进行更详细的调查。在政治和经济的混乱下，森林管理发生了重大变化。如果发生经济危机，俄罗斯政府正计划从林产品出口中获得更多硬通货，但这可能会导致森林砍伐和森林退化。库页州被指定为自由贸易区，州政府正在良好的空间引入市场经济。因此，森林砍伐和退化将是库页岛近期面临的严重问题。我们的调查还弄清了库页岛中南部的森林组成和结构，以及野生动物的生态。典型的调查在以下地点进行：1)北部分布边界的油松云杉林；2)南部分布边界的拉兹尼斯林；3)库页岛中部的冷杉-云杉森林；4)Optikha河的淡水鱼。

The former Soviet Far East has an enormous quantities of forest resources. The trend in the region influence the forest products available on world market, especially Japan, and timber exploitation in the region may cause serious environmental problems. Therefore more detailed investigation of the forest and forestry in the Far East is requested.Under the political and economic confusion, momentous change has been observed in forest management. In the event of -economic crisis, the Russian government is planning to get more hard currency from forest products export, but this may cause deforestation and degradation of forests. Sakhalin state was designated to free trade area and state government is introducing market economy at a good space. Therefore deforestation and degradation of forests in Sakhalin will be the serious problem near future.Our investigation also make clear the forest composition and structure, and ecology of wildlife in the central and southern part of Sakhalin. Typical investigations are carried out at the following places.1) Picea glehnii forest in its northern boundaries of distribution2) Lazix gmelini forest in its southern boundaries of distribution3) Abies-picea forest in the central part of Sakhalin.4) Fresh-water fishes in Optikha River.
