摘要: 为评价资源枯竭型城市转型期的生态质量时空演变特征,本文以阜新市中心城区为研究区域,基于Landsat遥感影像构建遥感生态指数(RSEI),以OSM数据和POI数据为基础识别城市功能区,借助参数最优地理探测器模型探究城市生态质量与城市功能区之间的复杂性关系。结果表明:①2004—2022年阜新市中心城区生态质量整体呈略微下降趋势、波动相对稳定,形成四周好、中间差的盆地状格局;②Hurst指数均值为0.67,强持续性最近邻指数值为146.53,生态质量未来变化趋势呈现均匀持续性,大部分区域变化趋势与过去相同,但局部地区有反持续性趋势;③识别出“31+1”类城市功能区,功能区生态质量由高到低依次为绿地、公共服务、工业、交通、居住、商业、矿区,且不同因子交互作用均会增强对生态质量的解释力。研究结果可为资源枯竭型城市转型期针对不同功能区的生态保护和恢复工作提供科学参考。

Abstract: In order to evaluate the spatio-temporal patterns of ecological quality in resource-depleted cities during the transition period.This article takes the central urban area of Fuxin as the research area, constructs a remote sensing ecological index(RSEI) based on Landsat images, and identifies urban functional areas based on OSM data and POI data. This article uses optimal parameters-based geographical detector to explore the complex relationship between urban ecological quality and urban functional areas. The results show:①From 2004 to 2022, the ecological quality showed a slight downward trend, with relatively stable fluctuations, forming a basin-like pattern with good surroundings and poor middle.②The average value of the Hurst index is 0.67, with a strong persistence nearest neighbor index value of 146.53.This indicates the future change trend of ecological quality shows uniform sustainability, the change trend of RSEI in most areas is the same as before, but there is an anti-sustainable trend in some areas.③“31+1” types of urban functional areas are identified, and the ecological quality of functional areas from high to low. They are green space, public services, industry, transportation, residential, commercial, and mining areas. Interactions among different factors enhance the explanatory power of ecological quality. The research results can provide scientific reference for ecological protection and restoration work in different functional areas during the transformation period of resource-depleted cities.
