摘  要：
【目的】利用物元模型对森林资源质量进行评价,以期为相关研究提供参考。【方法】根据评价目标和森林资源质量的定义建立森林资源质量评价指标体系,以1999年湖北省通山县森林资源二类调查数据为例,建立森林资源质量评价物元模型。【结果】1999年湖北省通山县森林资源质量等级为Ⅲ级,即良。用模糊综合法对数据进行分析,得出森林资源质量等级也是Ⅲ级,证明物元分析法可用于森林资源质量评价的研究。【结论】与模糊综合评价法相比,物元分析法无需人为给定指标权重,减少了评价过程中人为主观因素的影响,使评价结果更为客观。

摘  要：
[Objective] The present study was aimed to evaluate the quality of forest resources using matter-element model in order to provide references for relative research. [Method] Index system for evaluating forest resource quality was constructed according to the assessed objectives and their association with the forest resource quality. Based on the evaluation index system, the data of secondary forest resource inventory in Tongshan County, Hubei was used to establish a matter-element model for evaluating forest resource quality. [Result] The grade of forest resource quality of Tongshan County, Hubei in 1999 was evaluated as the third(good)on the basis of evaluation indexes. Further, when the forest resources were evaluated using fuzzy comprehensive evaluation method, the grade was also found to be the third. [Conclusion] The results revealed that the matter-element model was accurate for evaluating the forest resource quality. Compared with fuzzy comprehensive evaluation method, matter-element model does not need to weigh the evaluation index by person and avoids the effect of subjective factor. Consequently, the evaluation results are more objective and reasonable.
