<p>In this study, we will understand the actual situation of street trees maintenance management systems in local governments in Japan and the development status of street trees maintenance management plans and management guidelines. Next, this study was to understand the current state of the street trees maintenance management system and its impact, and to investigate the problems of citizen's participation in street trees maintenance management. As a result, street trees maintenance work is mainly done in the civil engineering road sector. In large local governments, staff specializes in landscaping, while in small local governments, it's mainly civil engineering. In addition, most street trees management methods are outsourced by contractors, with less than half direct management by staff. The policy to maintain street trees is positioned in many local government green master plans. Since 2015, local governments have developed conservation plans for street trees and are working on sound conservation. Since the 2000s, local governments have been working on maintenance management systems with the participation of residents. Most of them are road beautification activities based on adaptive systems. In the future, the challenge will be to further expand the system and raise citizen's interest and value perception.</p>

<p>This study aims to discuss the psychological process how the evaluation and perception of residential area or neighborhood parks were connected with the formation of attachment to residential area through neighborhood parks. Concretely, the structural equation modeling was conducted based on the results of questionnaire surveys for the residents in new town. In addition, this study targeted two areas with different resident's activities, "Suzaku area" and "Sakyo area" in new town where the site of "Basic Parks for Community Use" is planned because the relationship between "evaluation and perception of residential area or neighborhood parks" and "attachment to residential area" is discussed limited to the park. As a result, the following findings were obtained; 1) in both areas, "attachment to residential area" is influenced "attachment to neighborhood parks." And, the positive "evaluation of neighborhood park environment" and "involvement through participation into neighborhood park activities" encourages "attachment to residential area" through "evaluation of residential environment," "involvement through participation into residential activities" and "attachment to neighborhood parks." 2) The difference is revealed that "attachment to residential area" and "attachment to neighborhood parks" have influence on each other only in "Suzaku area" which residents pursue activities.</p>
