中文摘要	用16种化学方法对红壤、黑土、垆土、褐土、灰漠土五个典型土壤活性有机质进行测定,结果表明,333 mmol/L KMnO4常温振荡1h的方法测定结果变异系数小,重现性好,且操作简便快速,可作为土壤活性有机质测定的基本方法.虽然不同方法测定的活性有机质数量不同,但它们之间表现出较好的相关性,说明它们在一定程度上都可反映土壤有机质的活性.
英文摘要	Contents of labile organic matter in five typical Chinese soils including red soil, black soil, loess soil, fluvo-aquic soil and grey desert soil were measured using 16 chemical methods. The results showed that the method using 333 mmol/L KMnO_4 shaking for 1 hour could be used as basic method to determine labile organic matter in soil because it had some advantages such as good repeatable, smaller variance coefficient, simple and speed operation process. Moreover, the amount of labile orange matter varied with analysis method. Nevertheless, the data among methods were close relative generally, which indicated that different part of labile orange matter in soil was extracted by various methods.
