Lynch’s (1960) landmark work indicated that identity, structure, and meaning were major components of urban environmental images. His theory about five elements in Landscape, including paths, edges, districts, nodes, and landmarks which attributes to the identity and structure that form a place’ imageability.

    Nasar, (1989, 1998) focused on the importance of meaning and evaluation connected with the five environmental attributes that people associate with their evaluative image of place, based on Lynch’s work. The attributes include naturalness, upkeep, openness, historical significance and order.

 

    Lynch (1960)and Nasar(1998) emphasized the importance of environmental elements that influence a city’s image and community’s appearance.

Although Lynch(1960) recognized the importance of meaning and evaluation, his research emphasized identity and structure.

    Nasar(1998) argued that knowledge about imageability alone is not enough for shaping city appearance. People have feeling and associations, positive and negative, about their surrounding and imageable elements. These feeling and meanings are also crucial to people’s perception and reaction to the environment.

    Nasar(1997) described aesthetic quality as an evaluative aesthetic experience in relation to the environment. Aesthetic responses have probabilistic relationship to physical attribute to the environment. This probabilistic comes from the continuing interactional experience of people with their surroundings.

 

    Measures of an environmental aesthetic are often placed into two categories: perceptual/ cognitive response and emotional/affective response.

    Perceptual/cognitive response means identification and understanding of the factors that contribute to the understanding of an environmental attribute. Cognitive study examines how people evaluate and begin to understand visual cues.

    Emotional/ affective response often investigates the process of an individual’s evaluation of environments and the resulting emotion.

    Likeability. Nasar operationalized a city’s image as likeability of the cityscape focusing on the meanings that represent inferences about the quality and character of the place and its user

 

    The first objective of the study was to investigate aesthetic response dimensions of urban greenway trails. The second objective was to investigate the relationship between any aesthetic response dimensions that exist and the ‘likeability’ of urban greenway environments within them.

 

  For the Design of Veterinary Medicine College, I used Lynch‘s theory of five element in landscape for physical analysis of the site. The path represents the Lincoln Avenue, the road inside of the site, which is very important part of the transportation of the site. The Edges, include the edge for the site and the edge for different functional areas, are the define of the space. The district of the site include teaching and research district, clinic district, outdoor greenery district, which can hold different human activities; The node in the site represents for some landscape point which can provide a place for people to stay and enjoy; The landmark, including the sculpture in front of the entrance, is the identity of the college.

  I applied the Nasar’s five environmental attributes as the cultural and ecological analysis of the site. Naturalness. The naturalness indicates the green space, the vegetation cover, and the ecological function of the site; the upkeep can be the maintain of the site; the openness, represents for the welcoming of the outside visitors; the order of the site, including the students and faculties daily routine, the schedule calendar of the college.

  Different theory of analysis can result for different conclusion, but as a designer, we should combine these two way of thinking ,both rational and sensible, to think more about how to realize the true value of the site.
