新时期城市园林绿化评价指标研究——以徐州市为例

Research on the Evaluation Index of Urban Landscaping in the New Era——A Case Study of Xuzhou

从契合城乡建设发展新理念的角度出发,对城市园林绿化评价的部分指标进行更新和验证。蓝绿空间占比、蓝绿融合度、蓝绿用地连通度3个指标,不局限于绿地范畴,从生态系统服务角度评价城市生态系统的整体水平。深入分析不同类型绿地乔、灌木所占比例,能够促进城市绿地提质增效。为提升城市公园体系的服务功能,更好地满足市民休闲游憩需求,分别评价公园体系的服务半径。上述城市园林绿化评价新指标由国家生态园林城市——徐州的建设实践进行验证。

In line with the"ecological civilization"concept of urban and rural construction and development,some indicators of urban landscaping evaluation are updated and verified.The three indicators,the proportion of blue-green space,the degree of blue-green integration,and the degree of blue-green land connectivity,are used to evaluate the overall functions and services of the urban ecosystem rather than only the green space.The proportion of arbores and shrubs in different types of green space are conducive to promoting the quality and increase of urban green spaces and enhancing the capacity of carbon sinks.In order to improve the service functions of the urban park system and better meet the needs of citizens for leisure and recreation,the service radius of the park system was evaluated separately.The preservation of the city’s natural landscape pattern ensures the continuity of the city’s traditional style.All of the aforementioned new indicators of urban landscaping evaluation are verified by the construction practice of Xuzhou,a national ecological garden city.
