摘要

随着生态文明建设的发展,我国城市规划和发展进入了一个需要优化和建设生态空间的阶段。许昌作为国家宜居城市,近年来经济发展迅速,城市规模大幅扩张,对中心城区及周边地区的生态空间网络布局产生了影响。因此,识别和优化许昌市生态廊道的空间布局对于生态发展和公园城市建设至关重要。本研究利用多源地理空间数据识别和提取许昌市中心城区的生态廊道。利用生态阻力模型和重力模型,识别并验证了许昌市主要生态廊道格局位于魏都区这一中心城区。最后,划定了中心城区的 11 条主要生态廊道。针对生态廊道的确定,本研究综合运用空间分析方法和文本分析方法,对城市生态廊道的特征进行了评价。结果表明,许都公园向外延伸,是生态网络的枢纽,西湖公园和鹿鸣湖公园构成了城市公园系统的核心。最后,根据各生态廊道及其穿越的公园绿地的空间关系、生态效益和市民体验,提出了优化城市生态廊道布局的策略。

Identification and Analysis of Ecological Corridors in the Central Urban Area of Xuchang Based on Multi-Source Geospatial Data
With the development of ecological civilization construction, urban planning and development in China have entered a phase in which optimizing and constructing ecological spaces is required. As a national livable city, Xuchang has experienced rapid economic development in recent years, leading to significant urban expansion that has impacted the layout of ecological space networks in the central urban area and its surroundings. Therefore, identifying and optimizing the spatial layout of ecological corridors in Xuchang City are crucial for ecological development and park city construction. This study utilizes multisource geospatial data to identify and extract ecological corridors in the central urban area of Xuchang City. Ecological resistance and gravity models are employed to identify and verify that the primary ecological corridor pattern in Xuchang City is situated in Weidu District, which is a central urban area. Finally, 11 main ecological corridors in the central urban area are delineated. In response to the identification of ecological corridors, this study integrates spatial analysis methods and text analysis methods to evaluate the characteristics of urban ecological corridors. The results indicate that Xudu Park extends outward, serving as the hub of the ecological network, and that West Lake Park and Luming Lake Park form the core of the urban park system. Finally, based on the spatial relationships, ecological benefits, and citizen experience of each ecological corridor and the green parks it traverses, strategies for optimizing the layout of urban ecological corridors are proposed.
