城市发展使得城市公园逐渐孤立化、破碎化。研究依据层次分析法,制定了连接城市公园的游憩型绿道的评价指标因子和准则作为选线的依据,以北京三环内区域为研究范围,利用河流、交通线路等线性空间连接孤立的城市公园,构建了公园-绿干道-绿支道三个层次的绿道网络。研究同时发现,城市公园的面积越大,公共交通便捷度越高,对居民游憩活动的吸引力越大;河道沿岸绿化相对于水质对滨河游憩活动开展的影响更大;道路绿化覆盖率、与社区的连接度和道路等级对游憩活动开展至关重要。
Urban development makes the city park gradually isolated and fragmented. Based on the analytic hierarchy process (AHP), the evaluation index factors and criteria for the recreation greenways connecting urban parks were established as the basis for route selection. Taking the areas within Beijing’s Third Ring Road as the research area, linear spaces such as rivers and traffic routes were used to connect isolated cities Parks, build a park - Green Road - Green Branch three levels of greenway network. The study also found that the larger the area of urban parks, the higher the public transportation convenience, the greater the attraction to the residents’ recreational activities. The impacts of the greening along the river banks on the recreation of riverbanks are greater than the water quality; Community connectivity and road rankings are crucial to recreational activities.
