Abstract
This research aims at developing a greenway network design model for a developed urban area. Since Frederick Law Olmsted built the Emerald Necklace, greenways had become a landscape planning strategy because it provide a new point of view of landscape conservation and make the harmonious coexistence of human and nature more possible. Though numerous researches had developed greenway planning methods, the previous methods did not completely deal with a greenway’s multiple functions including recreation, transportation and ecological conservation. So the main purpose of this study is to develop a new greenway planning model by integrating the factors and relative disciplines about greenway planning into the model.
This study applies multiple criteria decision making approaches to develop a greenway planning model that considers human and ecological functions. The analytic network process (ANP) method is adopted to evaluate the significances of patches; and, the evaluation criterias include landscape metrics, species conservation, the accessibility to the hotspot of human activity, environmental vegetation situation and service facility. The multiple objective programing (MOP) method is used to formulate a network design problem for determining the optimal spatial distribution of greenways. The problem considers two objectives including maximum the utilities of human society and natural ecology, and the following constrains: cost, redundant cost, functions and range. To verify the rationality and applicability of the developed model, a case study of greenway planning in Taipei, Taiwan was conducted and concrete recommendation of greenway network alternatives were proposed to the city government. In the case study, expert survey and Super Decision package were applied in ANP analysis and Lingo package and weighting method algorithm were employed in MOP analysis.
The proposed greenway planning model contributes to interdisciplinary integrations. The MOP model has comprehensively analyzed the multi-functions of greenways; the ANP evaluation made the model more practical; and, the case study could provide some useful advices for the practicing of greenway plan in terms of such as the budget adjustments and concrete alternatives.
