东北、内蒙古四大森工集团是我国天然林资源主要分布区和国家重要的木材战略储备基地。自天保工程启动以来，天然林保护进展为世人瞩目。利用历次清查成果数据，对20世纪90年代年以来区域内森林资源变化特点进行研究分析。研究结果表明，东北、内蒙古四大森工集团的森林资源总量稳步增加，森林质量持续改善，林木长消盈余扩大，天然林保护取得重大成就。然而，四大森工集团森林过疏、过密现象普遍，中幼龄林面积比例大，用材林和珍贵、大径级树种资源少，不合理经营现象较为普遍，木材战略储备资源不足的状况仍未得到根本改变。针对四大森工集团森林保护发展存在的问题，有针对性的提出了加强天然林保护和森林经营管理的对策建议。
東北、內矇古四大森工集糰是我國天然林資源主要分佈區和國傢重要的木材戰略儲備基地。自天保工程啟動以來，天然林保護進展為世人矚目。利用歷次清查成果數據，對20世紀90年代年以來區域內森林資源變化特點進行研究分析。研究結果錶明，東北、內矇古四大森工集糰的森林資源總量穩步增加，森林質量持續改善，林木長消盈餘擴大，天然林保護取得重大成就。然而，四大森工集糰森林過疏、過密現象普遍，中幼齡林麵積比例大，用材林和珍貴、大徑級樹種資源少，不閤理經營現象較為普遍，木材戰略儲備資源不足的狀況仍未得到根本改變。針對四大森工集糰森林保護髮展存在的問題，有針對性的提齣瞭加彊天然林保護和森林經營管理的對策建議。

The four forest industry enterprise groups in Inner Mongolia and Northeast China are the major areas of natural forests in China and are the very important bases for wood reserve.The protection of natu-ral forests is the focus since the beginning of natural forest protection project.In this paper,the status of the forest resource in Inner Mongolia and Northeast China was analyzed based on the data acquired since the 1990s.The results showed that the general volume increased steadily,forest quality improved,the growth volume increased and cut volume decreased.More resources can be used and the natural forest protection project is successful.But as a whole,the forests in some areas are too sparse or too dense.The area of young and middle-aged forsrs is relatively larger,but the timber forest and precious,large DBH trees area is small.There still exist some irrational management practices and the lack of wood resources has not been changed.Based on the problems,some suggestions were proposed for natural forest protection and forest management.
