基于多评准决策的都市公园生态系统服务评估——以台中市公园为例

Urban Park Eco-system Services Evaluation Based on Multiple Criteria Decision Making—the Case Study of Parks in Taichung

近年来,生态系统服务的研究广受重视,都市规划者与居民也开始重视都市生态系统中所能发挥作用并做出贡献的服务功能,公园绿地作为都市环境组成的重要土地利用模式之一.是众多学者表明可以提供多样生态系统服务功能的重要场所,本研究通统服务的评估方式进行探讨,通过偏好序列结构法进行排序,初步探讨现有不同尺度与类型都市公园的生态系统服务功能评值。分析结果显示,面枳较大与树林所占面积较大的都市公园在生态系统服务上的提供相对起其他公园要更丰富。为不同专业领域的学者对于评估指标权重的看法亦有所差异。本研究初步探究出一个适合都市公园的评估工具,希望对于公园评估研究与景观规划实务上有所贡献。

In the passing years,the research on ecosystem services has received extensive concern,and urban planners,urban residents and,other relevant units have also begun to attach importance to the service functions that can be played and contnbuted to urban ecosystems.As one of the significant land use patterns composed of the urban environment,park greenbelt is also a significant place where a great number of scholars indicate that it can provide a variety of ecosystem service functions.In the current research,the evaluation methods of ecosystem services in urban parks are explored with the model of Multiple Criteria Decision Making,and the evaluation values of ecosystem services in existing urban parks of different scales and types are preliminarily probed into through ranking by means of PROMETHEE.The analysis results demonstrate that the provision of ecosystem services in urban parks with larger areas and forests is indeed richer than that in other parks,and scholars in different professional fields hold different views on the weight of evaluation indicators.In the current research,an evaluation tool suitable for urban parks has been initially developed,wishing to make a little bit contribution to park evaluation research and landscape planning practice.
