中文摘要：

卫生填埋是我国现阶段最主要的城市生活垃圾处理方式，定量分析城市生活垃圾可生物降解有机质成分对于研究填埋垃圾的厌氧降解过程具有重要意义。通过一系列常规化学试验，利用抽提差重法、比色法及灼烧差重法，依次测定了垃圾中含水率，挥发分与灰分，脂肪类，易水解物与半纤维素，腐植酸，难水解物、不水解物与纤维素，木质素与固体残渣等成分，为入场垃圾可生化性评价及降解过程中固相成分变化的动态监测提供了一种简便快速的测定方法。

英文摘要：

The sanitary landfill is main garbage disposal way in the present of China. The ingredient analysis of biodegradation organic substances has an important significance for estimating anaerobic degeneration process of the garbage. Through a series of routine chemical tests, the authors respectively determined the fats, hydrolysate and hemicellulose, humic acid, non-hydrolysate and cellulose, lignin in garbage. The test results provide a simple and fast monitoring method to evaluate dynamic biodegradation and solid change of the garbage.
