基于GIS空间分析技术,运用最小距离法和基于路网的行进成本分析法,对不同尺度的杭州城市休闲绿地空间可达性进行定量测度。研究结果表明:①杭州城市休闲绿地的平均可达时间为3.8 min,92.11%的居民可在10 min内到达一处休闲绿地;可达性最差(可达时间30~50 min)的居民区分布在主城区的边缘地带。②风景区类休闲绿地的可达时间为20.33 min,可达性最好的是西湖风景区绿地和西溪湿地风景区绿地。③各乡镇街道到风景区绿地的可达性呈现出以西湖为中心的不严格的圈层结构,距离西湖风景区越远,可达性越差。最后探讨了杭州城市休闲绿地可达性的差异,以期为城市休闲绿地研究提供新思路,为杭州城市休闲绿地的空间格局优化提供科学参考。 |

Urban leisure green space is a typical green open space very important for maintenance of urban ecological security and human health. Accessibility to urban leisure green spaces directly affects the quality of services for city dwellers and reflects the region's urbanization level. Accessibility to urban green spaces can be used as an indicator to assess the effectiveness of providing ecological services to residents of the green areas in current system and long-term future system. With socio-economic development, Chinese people and governments are paying much more attention to urban green spaces, and more and more citizens have the desire of contact with nature, and are willing to live close to urban green spaces. Consequently, governments plan to develop and optimize urban green space allocation to meet these demands. In this paper, a quantitative method based on landscape accessibility of green space in Hangzhou City was employed to improve index systems. Aided by GIS technique, this paper conducts analysis on the accessibility and service ability which considers the population densities of every district, applying the methods of buffer zone, minimum distance and travel. The results indicate that: (1) In Hangzhou City, on average it takes 3.8 minutes from a residential area to a urban leisure green space, and 92.11 percent of urban residents have access to a leisure green space within 10 minutes; the residential areas with poor accessibility are the outskirt areas of the city. (2) As to scenic-spot green spaces, their accessible time is 20.33 minutes. Xihu and Xixi are found to be much more accessible than other scenic spots. (3) The accessibility exhibits a structure of annulations centered around Xihu, the farther the distance is away from Xihu, the poorer the accessibility is. The work of this paper will help improve the key index system for assessing urban green spaces in China, and can provide planners and policymakers with important and valuable information for urban green space planning and assessment. |
