城市建筑

城市化加速使得城市土地资源稀缺，随着居民公共空间需求的增长，城市公园建设面临资源有限与需求增长的双重挑战。以天津市中心城区68个公园为例，构建了空间服务绩效与功能服务绩效评估体系。结果显示，中心城区公园服务绩效整体处于中低水平，综合公园表现最佳，空间与功能服务绩效不完全一致。除综合公园外，居民偏爱周边小绿地。未来应增建小型口袋公园，提升专类、社区公园服务质量。公园建设需考虑服务覆盖，避免资源浪费。本研究为城市公园服务绩效评估提供了新思路与方法，为公园管理优化与质量提升提供了科学参考。

The acceleration of urbanization has led to the scarcity of urban land resources and an increase in residents' demand for public space. The construction of urban parks faces the dual challenges of limited resources and increasing demand. This paper takes 68 parks in the central urban area of Tianjin as an example, and constructs an evaluation system for spatial service performance and functional service performance. The results showed that the overall performance of park services in the central urban area was low, with comprehensive parks performing the best, and the performance of spatial and functional services was not completely consistent. Besides the comprehensive parks, residents prefer small green spaces in the surrounding area. In the future, small pocket parks should be built to improve the service quality of specialized and community parks. The construction of parks needs to consider service coverage to avoid waste of resources. This paper provides new ideas and methods for the evaluation on urban park service performance, and provides scientific references for optimizing park management and improving quality.
