Landscape Evaluation Method Based on Analytic Hierarchy Process

In this paper, we concentrate on the problem of landscape evaluation which is of great importance in landscape design and construction. First of all, we present a landscape evaluation index system, which is made up of four kinds of indexes, such as "regional ecoenvironment", "social, cultural and residential environment", "man-made physical environment and ecocivilization construction" and "organizational management environment". Particularly, the proposed landscape evaluation index system is made up of 27 influencing factors, which cover all aspects related to the problem of landscape evaluation. The main innovations of this paper lie in that we introduce the analytic hierarchy process technology to calculate the index weights. To compute the priority vector effectively, we exploit the EV approach to tackle the eigenvector problem. Afterwards, the interval AHP is used to formulate the landscape evaluation problem to a linear programming problem. Finally, we design an experiment to testify the effectiveness of the proposed algorithm. Furthermore, data of ten famous landscape examples are collected to construct a dataset, and evaluation precision is used as measuring metric. Experimental results demonstrate that the proposed is effective in landscape evaluation.
