摘　　要：对辽河干流物理生境目前自然状况进行研究,为日后保护、修复与管理工作提供相关信息依据。选取相关因素,构建评价指标体系及相应的评价标准,利用模糊综合评价模型,得到辽河干流物理生境完整性评价结果。结果表明:辽河河流地貌特征为生物提供了较好的生存环境;水利工程有效地改善并恢复辽河的自然生态环境,对生态环境干扰度较小;辽河的水文特征表现对社会经济发展及人民生活质量的提高具有积极的作用。总体来说,辽河干流物理生境完整性处于"一般"状态。Providing relevant information basis will be used to protect, restore and manage Liaohe physical habitat＇s natural condition. This study selected related factors, constructs the evaluation index system and the corresponding evaluation standard, the fuzzy comprehensive evaluation model was used to get the results. The results showed that geomorphology features of Liaohe provide a good living environment for biont. The natural ecological environment of Liaohe would be effectively improved and restored by Water conservancy project that its disturbance degree is smaller. Hydrological characteristics of Liaohe performance has played a positive role on social economic development and the improvement of people＇s living quality. On the whole, Liaohe river physical habitat integrity is in a state of ＂general＂.
