The Jinan Xiaoqing River was reconstructed in 2019, which plays the role of the urban river with flood drainage, irrigation, waterway transportation, recreation, and other functions. Based on the landscape effect of the plant configuration patterns in six typical landscape sections of Xiaoqing River in Jinan, the relevant data was collected through a detailed sample survey. The concepts of horizontal and vertical structure in the plant allocation model were introduced to build the evaluation index system. Two methods of Analytic Hierarchy Process (AHP) and cluster analysis were used as comprehensive evaluation analyses for 16 plant allocation models in the study area. The results indicate that: The function attribute is the main factor in the influence factors of the criterion layer based on AHP, and safety and landscape sustainability are the primary influence factors of the index layer. The results between AHP and cluster analysis methods were slightly different. Still, both could screen out the best landscape configuration patterns M1, M2, M11, M13, and the worst plant configuration patterns M3, M8, and M9. Compared with AHP, the cluster analysis method is more realistic due to its dominated by objective evaluation. Therefore, combining subjective and objective analysis is more valuable for comprehensively evaluating the plant landscape effects.
