摘要: 公园城市理念为建成区多元要素的复合利用提供了新模式,其中,生态廊道作为城市生态系统的关键组成部分,承担着建成区各生态空间之间信息流动和物质交流的主要职能。本研究以兴趣点数据为数据源,在ArcGIS 10.2平台上识别沈阳市的生态(混合)空间并将其作为源地,再利用最小阻力模型和引力模型在阻力面上识别高阻力、中阻力和低阻力潜在生态廊道,最后根据潜在廊道分布特征提出空间规划引导策略。结果表明: 2017—2022年间,研究区生态(混合)空间数量显著增加,生态阻力面呈向外扩张趋势且核心区阻力持续累积,高阻力和中阻力潜在廊道各增加1条,低阻力潜在廊道增加9条,但存在廊道网络结构单一、生态孤岛现象加剧以及阻力不断累积的问题。从公园城市理念出发,针对潜在廊道空间分布特征,提出了强化复合空间廊道支撑体系的空间规划引导策略。

Abstract: The concept of park city provides a new model for the integrated utilization of multiple elements in built-up areas. Ecological corridors, as key components of urban ecosystem, play a major role in facilitating information flow and material exchange between various ecological spaces within built-up area. We identified ecological (mixed) spaces in Shenyang using points of interest data on the ArcGIS 10.2 platform and considered them as sources. Using the least-cost model and gravity model, we identified potential ecological corridors with high, medium, and low resistance on the resistance surface, and proposed the spatial planning guidance strategy based on the distribution characteristics of potential corridors. The results showed that the number of ecological (mixed) spaces in the study area significantly increased during 2017-2022. The ecological resistance surface showed an outward expansion trend with continuous accumulation of resistance in the core area. There was an increase of one high-resistance and one medium-resistance potential corridor, and an increase of nine low-resistance potential corridors. However, there were problems, such as a single corridor network structure, the exacerbation of ecological isolation, and continuous accumulation of resistance. Based on the concept of park city and the spatial distribution characteristics of potential corridors, we put forward a spatial planning guidance strategy to strengthen the support system of composite space corridors.
