摘　　要：分析了影响居民分布的因素,描述了居民分布曲线;根据居民分布曲线与 Langevin方程曲线的相似性,建立了基于Langevin方程的居民分布模型;通过模型求解过程,说明了模型参数在居民分布中的实际意义。居民分布的Langevin模型可以定量描述城市居民分布规律,揭示城市居民分布的宏观现象,为城市新建居民小区及改造交通系统提供科学的理论依据。The factors affecting the inhabitant distribution were discussed and the inhabitant distribution curves were described. From the similarity between the inhabitant distribution curve and the curve of Langevin equation an inhabitant distribution model based on Langevin equation was built. The actual implication of the model parameters were illustrated in detail along with the model solving process. The Langevin inhabitant distribution model can quantitatively describe the behavior of inhabitant distribution, reveal the macro-phenomenon of the urban inhabitant distribution, provide the scientific grounds for the inhabitant region construction and the traffic system reformation in the city.
