摘要/Abstract

摘要： 河流生境是河流生物赖以生存的环境，是维持河流生态完整性、维护河流健康的重要因素。本文结合蒲河流域环境特点，运用层次分析法建立了蒲河流域河流生境质量评价体系，对流域内25个河段的生境质量状况进行了综合评价，并进一步分析了河流生境综合评价指数与河流水质的相关关系。结果表明：（1）蒲河流域25个河段的生境质量状况差异显著，其中1个河段的生境质量等级为好，5个河段为较好等级，16个河段为一般等级，3个河段为较差等级。（2）生境综合评价指数与TP、NH₄⁺-N、COD_Cr呈负相关，生境质量评价体系中其他指标也与水质指标具有相关性，表明生境质量是影响水质的重要因素。

Abstract: River habitat is an important factor to maintain ecological integrity and river health. According to environmental characteristics of Puhe River Basin, a comprehensive river habitat assessment index system was established by using analytic hierarchy process. Habitat quality status of 25 sections of Puhe River Basin was evaluated. Correlation between the habitat quality indicators and water quality parameters were further evaluated. The results showed that: (1) Significant differences in habitat quality were found among the different sections. One section achieved the preferable level, 5 good, 16 fair, and 3 poor; (2) The comprehensive river habitat assessment index was negatively correlated with TP, NH₄⁺-N, COD_Cr, and other habitat quality indices were also correlated with the water quality index. It was indicated that habitat quality was a major factor impacting the water quality.
