驼梁森林健康评价研究

The Health Assessment of Tuoliang Forest

运用SPSS 11.5统计软件,通过因子分析法,在得到了可以反映驼梁森林健康的各个主成分的基础上,根据各样地B层指标的贡献率计算出样地A层指标的得分,然后采用专家打分法确定A层指标权重,进而计算出各样地的综合得分,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,为驼梁森林生态旅游的开发奠定理论基础。

Using statistics software SPSS 11.5, through the factor analysis method,on the basis of obtaining each principal component which could reflect health of Tuoliang forest ,according to the contribution rate of all kinds of sample B layer indicators ,the A layer index scores were calculated. Expert scoring method was used to determine A layer of index weight, and then the kinds of composite scores were calculated according to the score of high and low ranking of health.Through the analysis of evaluation results, some measures conducive to the interests of forest health were proposed, so as to provide theoretical basis for the development of ecological tourism of Tuoliang forest.
