摘要：

公园绿地和城市功能空间是城市空间的组成部分，研究公园绿地与城市功能空间耦合协调关系及其影响因素，对优化公园绿地合理布局，促进城市功能空间协同发展具有重要意义。以乌鲁木齐市中心城区为研究对象，运用核密度分析、标准差椭圆、耦合协调度模型和地理探测器等方法，在分析公园绿地与城市功能空间分布格局的基础之上，进一步探析二者空间的耦合协调关系及其影响因素。结果表明：（1）公园绿地与城市各功能空间形成了内密外疏、圈层式递减、向西北方向扩展的空间聚集特征。（2）公园绿地与城市各功能空间的分布重心均与城市中心发生了一定程度的偏离。公园绿地、居住空间、交通运输空间、公共服务空间呈西北—东南方向分布。休闲娱乐空间、商业空间呈东北—西南方向分布。（3）公园绿地与城市各功能空间耦合协调的主导类型为中度失调型，耦合协调度呈现出“中部高、东西两侧和南北两翼低”的空间分异特征。其中，人口因素、交通条件是影响公园绿地与城市各功能空间耦合协调度的主要因素，社会经济则是次要因素。

Abstract:

The study of the coupled coordination relationship between park green spaces and urban functional spaces, along with its influencing factors, is crucial for optimizing the layout of park green spaces and enhancing the synergistic development of urban functional spaces. This research focuses on the central urban area of Urumqi City, Xinjiang, China, employing kernel density analysis, standard deviation ellipse, coupling coordination degree model, and Geodetector. It aims to analyze the distribution patterns of park green spaces and urban functional spaces and investigate their coupling and coordination relationship and influencing factors. The findings reveal that: (1) Parks and urban functional spaces exhibit a spatial aggregation characteristic that is dense at the center and sparse at the edges, diminishing in concentric circles and expanding toward the northwest. (2) The distribution centers of parks and urban functional spaces have shifted away from the city center, with parks, residential, transportation, and public service spaces aligning in the northwest-southeast direction, while leisure and commercial spaces align in the northeast-southwest direction. (3) The predominant coupling and coordination type between park green spaces and various urban functional spaces is moderate dissonance, with the degree of coupling and coordination displaying spatial differentiation characterized by higher levels in the center and lower levels in the eastern, western side, and extremities of the north-south axis. Demographic factors and transportation conditions are identified as primary influences on the degree of coupling and coordination between parks and urban functional spaces, with socio-economic factors playing a secondary role.

Key words: POI data, park green space, urban functional space, coupling coordination, geodetector
