摘要
运用SPSS17.0数学统计软件,通过主成分分析法,在得到了可以反映鹫峰国家森林公园森林健康的各个主成分的基础上,根据各个主成分的贡献率计算出不同林分样地的综合得分,并按照得分的高低对健康状况进行排名。通过对评价结果进行分析,给出了一些有益于森林健康的措施,并说明了主成分分析在森林健康评价中的可行性与适用性。
In the use of SPSS 17.0 Mathematics and Statistics software, we have received various principal components which can reflect forest healthy of Jiufeng National Forest Park through the principal component analysis. Based on these, we may calculate synthesized score of different forest plot according to the contributed rate of each principal component. And healthy status of different forest plot is ranked in accordance with the level of scores. The article may give some useful measures for forest health and describes that the principal component analysis is feasible and practical in the forest health evaluation.
