摘要: 本文对吉林省气候、土壤、地形和地质等三十四项森林生态指标进行了主成分分析,并在此基础上,对本省四十二个森林生态县进行了聚类分析,用判别分析检验了分类结果的可靠性。通过数量分类方法,将吉林省全域区划为5个森林生态区,为森林生态系统的管护和开发利用提供了科学依据。

Abstract: On the basis of analysing 34 forest ecological factors about climate, soil, landforms and. geology, 42 forest ecological counties are classified with cluster analysis and principal component analysis (PCA) and the reliability of 5 alternative of classification are examined with the method of discriminant analysis. With the aid of said numerical classification, 42 forest ecological counties of Jilin Province has merged into five forest ecological districts.Brief description of each district is given which will provide scientific basis for the conservancy and administration of forest ecological system.
