This study aims to propose a series of indicators that describe the characteristics of landscape elements, which can be used to predict the psychological evaluation of river landscape complexity and openness. Firstly, we proposed the indicators which is applicable for landscape image in previous study. Then we conducted a psychological evaluation experiment using 48 images that demonstrate different patterns of buildings and trees. According to the result, this study added indicators specifically tailored for landscape images contain trees. Finally, a predictive model performed well, which is applied to predict complexity and openness of landscapes with greenery, is constructed.
