This article aims to explore the characteristics of Guangzhou Xingfong Landfill leachate, and pro- vides theoretical bases for technical transformation project. Through analysing the values of pH, COD and BOD: in Xingfeng landfill leachate from 2005 to 2009 ,the results show that:Guangzhou Xingfeng solid waste landfill has been advanced into the "aging" stage;pH has stabilized in the range of 7.73 to 8.2 since 2009, which has an increasing trend; COD and BOD5 are significantly decreased but remain at a high value, and there is a clear correlation between the two; the BOD5/COD range from 0.48 to 0. 19, and this poor biode- gradability may cause some difficulties in biochemical treatment of leachate.%通过对2005～2011年兴丰垃圾填埋场渗滤液中pH值、COD和BOD3浓度变化分析，结果表明：广州兴丰生活垃圾填埋场已提前进入“老龄化”阶段，自2009年以来渗滤液中pH值稳定在7．73～8．24之间，且有增大的趋势；COD和BOD3均有大幅度下降，但仍保持较高值，两者间有明显的相关性；BOD5／COD的值介于0．48～0．19之间，可生化性差。
