摘　　要：网络论坛是我国互联网舆论形成的重要力量之一,正引起社会各方的广泛关注.通过对大量实际数据的统计分析,发现网络论坛发帖量满足:幂次定律、自相似性、1/f噪声和捷夫定律.说明网络论坛是一个复杂的自组织临界态系统.应用自组织临界理论可以分析网络突发事件和舆论形成中的诸多现象.最后提出一种评价网络论坛舆论的定量指标.实验表明,该指标能有效发现网络论坛突发事件.Network forum in China is one of the main sources of the public opinions and it plays more significant roles in social life than before. This paper analyzed massive data from one of the real network forums, and finds that some phenomena satisfy the theories of the power law, the self- similarity, the 1/f noise and the Zipf law. They mean that the network forum is one of the SOC （self organization critical） systems. Applying the self organization critical theory can explain how the paroxysmal events happened and how the web opinions formed. Finally, a quantitative criterion for web opinions is presented, and it can detect the paroxysmal events, which is demonstrated with a series of experiments.
