The environmental degradation of a city is mainly caused by its large numbers of dense buildings and structures. To green the limited exterior space outside a construction foundation has limited effect on improving the ecosystem and micro-climate of the environment since the plants are scattered and cannot form communities. This study will investigate the structure and composition of the green ecosystem in an urban system, and then propose the impact factors and assessment framework of urban green resources to be taken as a reference for a city’s green system. The underlying theoretical basis of this study is chiefly the "Landscape Ecology" and its related theories. Additionally, the study takes into account the existing domestic green policies and issues of urban environment. The study tries to identify the relationship of the urban ecological systems in Taiwan, observe the influence of changes in the trends of urban ecology, and describe qualitatively the ecological services provided by urban green resources. By applying the "Validity of Survey," an objective and efficient consensus-forming mode of operation, the study will determine the assessment factors in the simulation process. The Analytic Hierarchy Process Theory (AHP) displays function structures and evaluates the weight given to different assessment factors so that impact factors in the ecological assessment system of the urban green resources can be found. The research results will provide some insight into what issues to focus or avoid for future implementation of ecological planning.
