|Since UNEP, IUCN and WWF provoked the idea of “sustainable development” of a city in 1980, the establishment of greenspace system became a worldwide issue of urban development However, the urban greenspace in Taiwan has not reached its function because of the fragment and unfitting allocation. Therefore, the study tried to develop a theoretical framework for establishing an evaluation model based on the landscape ecology point of view. It tried to examine the evaluation factors of the allocation of urban parks and greenspace. Aiming at the structure, feature, and fitting allocation of urban parks and greenspace, the study underwent two-phases of questionnaire conducting by experts. In phase one, the questionnaire carried Fuzzy Delphi method to examine and choose the evaluation factors of the allocation of urban parks & green space. Evaluation factors included three hierarchies. The first hierarchy included the criteria of “completeness of physical ecology” and “cultural functions”. While hierarchy the second included “context”, “ecological functions”, “recreational functions”, and “cultural functions”. The third hierarchy included sixteen criteria, such as “area of park or greenspace”, etc. In phase two, the questionnaire applied Fuzzy Analytic Hierarchy process Method to obtain the comparison value of each pair of factors. Then the study utilized the calculate process of Similarity Aggregation Method to obtain the weight of each individual factor. Finally, the evaluation framework of the allocation of urban parks and greenspace was established.
The evaluation framework was applied to Dong-Feng Park and Feng-Ler Park in Taichung city as case studies. It was found that the completeness of physical ecology in Dong-Feng Park is superior to Feng-Ler Park, because of its fine spatial structure and functions of landscape. While the cultural functions of Feng-Ler Park is superior to Dong-Feng Park, because there are various opportunities to recreate. The evaluation outcome indicated that how does the importance of the influence of physical environment of the sites to the ecological allocation. The result could be used as a reference for future planning, design, and improvement of parks and greenspace. Furthermore, it also could be a foundation of ecological assessment for urban greenspace system.
