公园城市理念下建成区复合生态廊道识别与空间规划引导:以沈阳市中心城区为例
Identification of composite ecological corridors and spatial planning guidance in built-up areas under the concept of park city:Taking Shenyang City Center as an example
摘要
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 out-ward 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 corri-dors.However,there were problems,such as a single corridor network structure,the exacerbation of ecological iso-lation,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.关键词
