| 摘 要： | 在分区选择典型样点的基础上，从土地利用结构类型和土地利用强度等方面对中国东北带（ＮＥＣＴ）近年来的土地利用变化进行分析，揭示出样带上土地利用发生变化较剧烈的区域为农牧交错带，变化的原因主要是人类活动强度的增加。此结论对样带上的生态敏感区域制定土地利用开发与管理下策应具有意义。

| Abstract: | On the basis of selected 7 sample areas along NECT according to the land-use and land cover,this paper analyzed the land-use change relating to the land-use structure and intensity in NECT during 1984-1996.The preliminary results show that significant land-use change has occurred in the transitional zone between agricultural and pastoral regions,and the change is mainly induced human activities.This preliminary conclusion might have some significance for land-use exploitation and management in those ecological fragile areas in NECT. |
