| Summary: | 碩士 === 逢甲大學 === 土地管理所 === 90 === With the rising economic development, people pay more attention to the quality of their living environment such that the reasonable and effective assessment of living environmental quality becomes an important issue for urban residents now in Taiwan. Because the assessment of living environment quality lacks well-accepted and practical measurements and is difficult to be quantified, the procedures of environmental quality evaluation is often involved with fuzzy property. Therefore, this study utilized fuzzy theory to assess the qualitative indices of the living environment quality and established an evaluation structure that objectively presents the cognition of some selected experts.
In this thesis, a living environment quality evaluation system was constituted and then applied to four urban communities of Taichung. With secondhand information and GIS (Geographic Information System) analysis results, the related data of these communities and their differences in living environment quality were discovered. In this study, the fuzzy numbers were calculated from the linguistic variable of fuzzy theory to represent the importance of the evaluation indices and then the fuzzy membership function of each evaluation index was built. The evaluated results of the fuzzy comprehensive judgment were compared with those of the eighteen experts.
The study results indicated that the community security is the most important factor of living environmental quality and followed by maintenance of disaster prevention/rescue facilities, while the accessibility of public service organization was considered as the most unimportant factor. With the fuzzy membership function, the five-level distribution of each evaluation index for all communities was found based on the questionnaire results from our experts. The evaluation results of four communities based on fuzzy theory discovered that three of them were ideally consistent with the results of the experts.
