Abstract: Aiming at the problems of poor allocation accuracy and low environmental contribution rate in landscape plant allocation methods, a landscape plant allocation method based on comprehensive evaluation index method is proposed in this paper. First, he spatial state of abstract landscape plant configuration is regarded as the spatial sequence of specific configuration points and lines, and the characteristics of different levels of space are constructed. Then, calculate the index weight with the help of analytic hierarchy process to complete the construction of allocation index system. Finally, with the help of the comprehensive evaluation index method, the single category factor index and similar index are determined, the contribution rate of configured plants to the environmental impact is calculated, the landscape plant configuration model is constructed, and the landscape plant configuration is completed. The results show that the configuration accuracy of the proposed method is high.

Keywords: comprehensive evaluation index method; hierarchical features; Markov chain; contribution rate; flexibility.
