Quantifying urban disaster resilience is needed to strengthen the capacity of urban disaster prevention and mitigation strategies. In previous studies, the spatial unit used for urban disaster resilience assessment was coarse, which could easily cause local differences to be overlooked. To rectify the problem, this study integrated high spatial-resolution urban grid data and built an index system from economic, social, administrative, and technological dimensions. On this basis, both exponential decay function and spatial analysis techniques were applied to establish a high-precision evaluation method of urban disaster resilience. The results showed that the urban disaster resilience of Futian District (FTUDRI) had a certain spatial aggregation effect, with an average of 0.37 ± 0.08, which was at a middle level. Areas with low and middle-low levels of FTUDRI which accounted for 27.28% were mainly located in the western, northern, and southern edges of Futian District, with undeveloped economy and inadequate emergency infrastructures. We considered the neighborhood impact of point indicators on urban disaster resilience and the results indicated if we neglected this there would be an underestimation of the urban disaster resilience assessment. Hospitals, administrations, and emergency material points were key driving indicators for improving FTUDRI. In conclusion, our results demonstrated the necessity of pursuing high-resolution urban disaster resilience assessments and the effectiveness of the newly proposed method. The results of this study can provide policymakers with a clear location of where a low level of urban disaster resilience occurs, providing a basis for urban disaster prevention and improvement measures.

需要量化城市抗灾能力，以增强城市防灾和减灾战略的能力。在以前的研究中，用于城市抗灾能力评估的空间单位是粗糙的，很容易导致局部差异被忽略。为了纠正这一问题，本研究整合了具有高空间分辨率的城市网格数据，并从经济，社会，行政和技术维度构建了一个指标体系。在此基础上，结合指数衰减函数和空间分析技术，建立了城市灾害抗灾力的高精度评估方法。结果表明，福田区城市抗灾能力具有一定的空间聚集效应，平均为0.37±0.08，处于中等水平。FTUDRI水平较低和中低水平的地区占27.28％，主要位于福田区的西部，北部和南部边缘，经济不发达，应急基础设施不足。我们考虑了点指标对城市抗灾能力的邻里影响，如果我们忽略了这一点，那么结果表明，城市抗灾能力评估将被低估。医院，行政管理部门和紧急物资要点是改善FTUDRI的关键驱动指标。总之，我们的结果证明了进行高分辨率城市灾难复原力评估的必要性以及新方法的有效性。这项研究的结果可以为决策者提供一个清晰的位置，以了解发生低水平的城市灾难复原力的地方，
