摘  要：
基于模糊评价模型对森林质量进行评价,主要方法是解决各个指标权重的问题。以红花尔基森林资源二类调查数据为基础,探讨4种赋权方法对其评价结果的影响,分别利用层次分析法、主成分分析法、熵权法、专家直接打分法确定其权重,并比较分析不同赋权方法得出的权重值与评价结果。结果表明,主成分与专家直接打分法得出各指标权重结果大致相同,得出的森林质量等级均为Ⅱ级;层次分析法与熵权法指标权重结果存在明显差异,得出的森林质量等级为Ⅲ级。分析表明主成分分析法和专家直接打分法在确定权重方面较其他2种赋权方法更为准确,获得的评价结果更符合实际状况。

摘  要：
Forest quality was assessed by using the model of fuzzy evaluation.The main issue of the assessment was to determine the weight of each index.Based on the second survey data of Honghuaerji,impacts of four weight determining methods on the results of the assessment were discussed.Four methods included analytic hierarchy process(AHP),principal component analysis(PCA),entropy weight,and expert scoring.Values of weight obtained from different methods and related assessment results were compared and analyzed.The results showed that the weight values calculated by the weighting method of PCA were similar to the evaluation results of expert scoring method,and the results belonged to the second grade.AHP method and entropy weight method gave different weight values of each index,and the results belonged to the third grade.The final result indicated that methods of PCA and expert scoring were more accurate than the other two methods,and more approximate to the actual situation.
