摘要
城市公园空间布局直接影响到公园的使用、社会公平,影响着社会、生态功效的发挥。本文采用不同计算方法,比较计算方法,并深入分析基于道路网络可达性分析方法的机理。结果表明:①基于道路网络的算法可以更准确地评价城市公园的可达性;②济南城市公园数量不足,只有约1/3的市民可以方便的使用公园,人均公园占有量与国际都市差距甚远;③济南城市公园空间分布不均衡:市中区可达性较好,主城区高于外围区域,总体上从主城区向外呈辐射状减弱的趋势。
A city park' s spatial layout represents the justice of social equity,subsequently influencing its social and ecological function. In this paper,a mechanism model and its calculation method of accessibility were deeply discussed.The results show that:①Network analysis,based on road network more accurately assesses accessibility of urban parks;(2) Jinan city is in lack of urban parks, only about one in fifth of the residents can use parks conveniently,and there is a remarkable distance in park area per capita compared to international cites;③spatial distribution of urban parks is uneven:Shizhong district has a better accessibility,the urban area is better than the surrounding area,and accessibility shows a trend of weaking from downtown to the outside.
