(R. Kaplan, 2001; R. Kaplan & Kaplan, 1989; Purcell & Lamb, 1984; Ulrich, 1986). This means that a greater proportion of natural areas can promote an environmental preference in urban areas (van Den Berg, Hartig and Staats, 2007). Additionally, significant positive correlations were found between landscape preferences and landscape heterogeneity and diversity (Dramstad et al., 2006; Franco, Franco, Mannino, & Zanetto, 2003; Lee et al., 2008; Palmer, 2004). Their results suggest that landscapes that function ecologically (e.g. less fragmented and more heterogeneous) are more attractive (Forman, 1995; Lee et al., 2008). For example, urban residents are more likely to be satisfied with their neighborhood environment when it contains large, connected patches of trees that are considered to function better ecologically (Lee et al., 2008). . However, some researchers hold opposing views regarding the relationships between ecological landscape and human preferences (Gobster, 1994; Steinitz, 1990). Parsons (1995) suggests that environmentally sustainable environments are perceived as less attractive. Steinitz (1990) conducted a study in a US national park and observed significant conflicts between visual preferences and landscape sustainability. However, few empirical works have reported similar results for urban green spaces or
