摘　　要：广州流溪河是广州市的一条重要河流,对广州市的社会经济、水利资源与生态环境都有着重要的影响。生态修复是近年来我国学者研究的热点,为了更加了解流溪河整体的生态健康状态,选取从化区的流溪河段,采用模糊概率评价的方法对流溪河的生态系统进行评价。结论是流溪河从化调查段总体上处于近自然状态,受人为干扰的情况较少,近自然特征明显,整个调查河段,自然状态占26.7%,近自然状态占53.2%,退化状态占16.9%,完全人工化状态占3.2%。Liuxi River is one of the most important rivers in Guangzhou, which is of great importance for the economy, water resources and ecological environment of Guangzhou. Ecological restoration is one of the research focuses recently. In order to better understand the ecological health of the whole river, in this paper, the flow stream reach of Liuxi River Conghua section is selected, ecosystem health evaluation method using fuzzy probability evaluation of the Liuxi River. The conclusion is that the river in the near natural state in general and it is less affected by human disturbance. Significant near natural features. The whole survey reach, the natural state accounted for 26.7%, in the near natural state accounted for 53.2%, the state of degradation accounted for 16.9%, completely artificial state accounted for 3.2%.
