基于枯落物分解原理，分析现有4种枯落物分解试验方法，即：野外分解袋法、实验室模拟分解法、现量估算法和综合平衡法各自的特点和适用范围。评价传统的研究枯落物分解的Olson指数衰减模型和修正Olson模型，结合东北林区的特点，建议一般采用野外分解袋法收集林区枯落物分解实验材料，延用01son模型进行计算，优于其他三种方法。

Based on litter decomposition theory, the features and application scope of the four experiment~ methods, namely field deeompos!tion bag method, laboratory simulation method, present amount estimation method and overall balance method were all analyzed. The traditional Olson exponential decay model and the revised Olson model that were used to study fitter decomposition were evaluated. Combined with the characteristics of Northeast forestry area, it is recommended to adopt field decomposition bag method to collect forest litter for experiment, and then calculate it by Olson model.
