摘要：
Because the traditional evaluation method of urban green space landscape spatial structure has the problems of low evaluation accuracy and long evaluation time, an evaluation method of urban green space landscape spatial structure based on entropy weight method is proposed. Firstly, under the selection principle of evaluation indicators, the evaluation index system of urban green space landscape spatial structure is constructed, and the evaluation indicators are obtained. Then, the trend surface filtering method is used to detect the abnormal data in the evaluation index data, and then according to the detection results, the entropy weight method is used to determine the weight of the evaluation index. Finally, based on the determined weight value, the comprehensive evaluation of urban green space landscape spatial structure is carried out. The simulation results show that the proposed method has higher accuracy and shorter evaluation time for urban green space landscape spatial structure evaluation.
