Urban heat island effect evaluation method based on atmosphere reanalysis data

The invention discloses an urban heat island effect evaluation method based on atmospheric reanalysis data, and the method comprises the steps: obtaining the related data of an urban heat island, and carrying out the preprocessing of the related data; based on the preprocessed data, a typical heat island form is determined; based on the typical heat island form, obtaining a typical heat island mean value, and evaluating the typical heat island mean value; and obtaining a typical heat island area ratio based on the typical heat island form and the evaluation result, and obtaining a heat island range and degree influenced by urbanization according to the typical heat island area ratio. The heat island evaluation method is simple, scientific and objective, and can provide a new angle and tool for urban meteorological research. 本发明公开了一种基于大气再分析资料的城市热岛效应评估方法，包括：获取城市热岛的相关数据，并对所述相关数据进行预处理；基于预处理后的数据，确定典型热岛形态；基于所述典型热岛形态，获取典型热岛均值，并对所述典型热岛均值进行评估；基于所述典型热岛形态和评估结果，获取典型热岛面积比，根据所述典型热岛面积比，获取城市化影响的热岛范围和程度。本发明的热岛评估方法简单、科学、客观，可为城
