To clarify the differences in the landscape environment quality of urban country parks, we used the analytic hierarchy process method (AHP) and the approaching ideal solution method (TOPSIS) to build a criterion layer from four points of view: ecological environment, visual landscape, service facilities and humanistic landscape. We selected 21 evaluation factors to form an index layer to evaluate the landscape quality of four country parks in Shanghai. The AHP- TOPSIS evaluation system was validated using the post occupancy evaluation method (POE) to verify the accuracy and appropriateness of the system. We proposed landscape improvement strategies based on the evaluation results. The results showed that the combined AHP-TOPSIS-POE model can be used to effectively assign weights to evaluation indexes when evaluating the landscape quality of country parks and to avoid the one-sidedness of single-factor decision making and the errors caused by human subjective factors. The AHP-TOPSIS-POE model provides a new framework for evaluating the landscape quality of urban country parks.
