摘要:
河流生境质量评价是河流综合健康评价的关键组成部分,也是河流评价管理的重要手段.选择涵盖袁河干流和支流的30个调查点进行河流生境质量调查和评价,采用了反映河道、河岸和滨岸带生境状况的10个指标,建立河流生境质量评价体系,进行河流生境质量评价和等级划分.进一步研究评价结果与河流水质、河流近岸土地利用状况以及底栖动物群落的相关性,以便验证河流生境指标体系对河流状态的的表征状况,探讨影响河流生境的关键因素.研究结果表明:(i)袁河河流生境质量指数综合得分介于32～81,全流域83.4%的调查点处于中等及以上水平,总体质量状况较好;(ii)大型底栖动物种类数和多样性指数与河流生境质量关系密切,尤其是滨岸带生境;(iii)袁河河流生境质量状况与200 m、500 m缓冲区内的林地显著正相关,与建筑用地显著负相关,且相关系数在空间尺度上存在差异;(iv)袁河流域生境质量指数与CODMn显著负相关,影响河流生境的主要水质因素为有机污染物.
Abstract:
A key component of comprehensive river health assessment is river habitat quality assessment,useful for river evaluation and management and applicable to any river basin.In this study,thirty river sections covering the main stream and tributariesof the Yuanhe River are analyzed for river habitat quality assessment.Ten indicators(associated with bank, channel and riparian zoneproperties)are selected to construct thisriver habitat quality assessment system,and the evaluation results are divided into five grades according to the grading standard of the evaluation index.To verify the status accuracy of the river habitat indicator system on river status and to explore the key factors affecting influencing river habitat health,we analyzed the correlations between the evaluation results and water quality,river nearshore land use status,and benthic step community are analyzed.The results reveal that the river habitat index(ranging from 32 to 81)with rated mostsectionsasin good and fair status,though a few river sections exhibit the less healthy status(e.g.,monotonousbed material,high hardening level bank and/or a seriously disturbed riparian zone).The species number and diversity index of macrobenthos are closely related to the river habitat quality,especially inriparian zone.Habitat quality is positively correlated with forested land and negatively correlated with anthropogenically developed or developing land.The river habitat quality index is negatively correlated with CODMn,an organic pollutant and the main contaminant in Yuanhe River Basin.
