摘　　要：[目的]揭示牛栏河的生态现状,为今后生态治理和修复工程提供依据。[方法]通过对研究河段的水质状况、河岸带状况和污染来源等进行实地调查,并采用综合评价方法对调查数据进行评价。[结果]牛栏河整体近自然状况较好,研究河段8—10号河段均处于自然状态,3,5—7号河段均处于近自然状态,1,2,3号河段均处于退化自然状态;牛栏河总体水质较差,继续进行河流的生态修复与治理,有由下游到上游逐渐变好的趋势。[结论]研究河段的主要污染源为养殖粪便污染、生活垃圾污染以及生活污水污染,在今后牛栏河的治理中应着重考虑这些问题。[Objective] The ecological condition in the Niulan River was investigated to provide bases for ecological management and restoration project. [Methods] Based on the investigation of water quality, riparian zone and pollution sources of the study reach, a comprehensive evaluation method was used to evaluate the survey data. [Results] The natural condition of Kraal River is good. Of which, reaches of 8-10 are in the state of nature, 3, 5-7 reaches are in near natural state, 1, 2, 3 reaches are in a degraded natural condition. The water quality of Kraal River is general poor. If river harnessing being continued, the water quality would improve from downstream to upstream gradually. [Conclusion] The main pollution sources of the study reach are manure, garbage pollution and sewage pollution. Therefore, in the future governance, these pollution should be focused.
