辽河干流物理生境完整性灰色综合评价

Grey Clustering Evaluation for Liaohe River Physical Habitat Integrity

通过对相关影响因子的分析,提出了评价指标体系及评价标准。根据选取的各指标的特点,采用灰色聚类方法进行定量综合分析,通过灰色聚类综合模型在辽河物理生境完整性评价上的应用,验证了该模型的可行性和有效性。评价结果表明,辽河干流物理生境完整性程度总体上处于"一般"的状态,需要给予更多的保护。

Through the analysis of relevant factors,this paper put forward the evaluation index system and evaluation standard. According to the in-dex characteristics and using the comprehensive analysis of the grey clustering method quantitatively,this paper verified the feasibility and effective-ness of the grey clustering model,through the application in Liaohe physical habitat integrity assessment. The results show that the physical habitat integrity of Liaohe River has been evaluated as“general”grade and more protection should be given.
