The rapid growth of urbanization has caused the intertwined relationship between the man-made system and the Earth development more dynamical and complicated. As the main link connecting the urban and environment, fuel energy has always been one of the hop-spots in recent scientific research. This paper proposed a novel method to estimate the mass of fuel load from urban area. The model comprehensively studied the parameter, fire load density (FLD), which is used to account for the total energy released by the surveyed building. A database of FLD was founded to investigate the influence of building type. In order to compile the urban land-use area in orderly manner, this study developed a classification of land-use type such as residential, commercial, business and the other six categories. Then, this paper described the conceptual framework that how to calculate total amount of fuel energy released and mass of various combustible materials in urban area. Additionally, the proposed model was applied in Washington D.C as case study. According to D.C. Zone Planning, the entire D.C. was divided into eight wards, which containing ten district area. The total area of each district was divided into the eight categories of land-use types. Finally, the models presented the mass distributions of various combustible materials in all districts of Washington D.C. Moreover, the differences in the fuel mass per capita among each district demonstrate that the different distribution areas of various land-use type show the significant influence on the fuel mass quantities.

城市化的快速发展使人为系统与地球发展之间的纠缠关系更加动态和复杂。作为连接城市与环境的主要纽带，燃料一直是最近科学研究的热点之一。本文提出了一种新的方法来估算市区的燃料负荷量。该模型全面研究了参数火荷载密度（FLD），该参数用于说明被调查建筑物释放的总能量。建立了FLD数据库，以调查建筑类型的影响。为了有序地编制城市土地利用区域，本研究对土地利用类型进行了分类，例如住宅，商业，商业和其他六个类别。然后，本文描述了一个概念框架，该概念框架如何计算城市地区释放的燃料能量总量和各种可燃材料的质量。此外，建议的模型已在华盛顿特区作为案例研究应用。根据区议会规划，整个区议会分为八个区，其中包括十个区。每个地区的总面积分为八类土地利用类型。最后，模型显示了华盛顿特区所有地区各种可燃材料的质量分布。此外，每个地区人均燃料质量的差异表明，不同土地利用类型的不同分布区域对燃料的影响显着。质量数量。
