摘　　要： 通过对现有历史资料的分析,结合已有研究成果,对我国晋北6个典型历史时期森林生态系统的系统状况、发展诱因、系统后果及系统运动进行了全面的分析研究。研究表明,除建国后晋北森林稍有恢复外,历史上晋北的森林生态系统随时间的推移退化程度越来越高,而人类活动是导致晋北森林退化的根本原因。人类活动对晋北森林生态系统的破坏由易到难、由近至远,破坏的大体顺序是由平川盆地至低山区,由低山区至高山区,直至山区森林被摧毁殆尽。 Through the analysis of both existing historical data and existing research results,we thoroughly studied the systematic situation,developmental causes,systematic consequences and systematic movement of forest ecosystem in six typical historical periods of northern Shanxi province in China. The results indicated that： throughout the history,the forest ecosystem in northern Shanxi province degraded more and more seriously except for it got a little recovery after the foundation of China. The human activity was the root cause leading to the degradation of forest ecosystem in northern Shanxi province. The destruction of forest ecosystem in northern Shanxi province caused by human activity became from easy to difficult,and from near to far. The forest ecosystems in the plain and basin were destructed firstly,followed by those in low mountainous area and high mountainous area in sequence.
