Urban forests provide multiple services including ecological, social, and economic benefits. Several evaluation programs for urban forest services have been developed in the US and applied to urban forest policy. However, there is no comprehensive program in Korea to evaluate the multiple services. This study developed a computer evaluation model for the multiple services suitable for structural characteristics of urban forests in Korea. Development of the model used the Python-based Django and the Plotly for statistical analysis. The multiple services for evaluation included carbon sequestration, abatement of various air pollutants, O2 production, microclimate amelioration, building energy saving, rainfall interception, erosion control, bird diversity enhancement, psychological welfare, and property value. This evaluation model can be applied to estimate urban forest services at the per tree level and at the per unit level through input parameters such as tree sizes and weather conditions. The model is also capable of spatial analysis and mapping as required for urban forest planning to enhance the multiple services. This new model is expected to be practical in easily quantifying urban forest services and in establishing guidelines of urban forest design and management.
