摘　　要：The degradation of the eco-environment has been a challenge for sustainability in resource-based cities around the world.Although much attention has been drawn to this issue,few insights have been acquired regarding the spatial differentiation and mechanism of the factors influencing habitat quality in resource-based cities from the perspective of the interactions of natural and human factors.Using Tangshan City as a case study,this paper evaluates habitat quality by integrating Ecosystem Service Value Assessment and the InVEST-HQ model,identifies the spatial distribution of Tangshan’s habitat quality with spatial auto-correlation,and explores the influencing factors and their mechanism of influence on the spatial differentiation with the geographical detector model and Space production theory.The results show that:(1)The total value of the habitat quality in Tangshan City in 2019 was 3.45×10^(10) yuan,and the habitat quality value was 24435.05 yuan ha-1.The habitat quality value presents a clustered distribution pattern of"hot in the north and the south,cold from the center to the west".(2)On the county scale,Qianxi County had the best habitat quality and Lubei District had the worst habitat quality;Shangying Township had the highest average habitat quality and Kaiping Street had the lowest average habitat quality in the township unit.(3)The results of geographical detectors show that natural environmental conditions are the important basic factors affecting the spatial differentiation of habitat quality in Tangshan City,while urbanization and industrialization factors are the most important external forces driving the spatial differentiation of habitat quality.The contributions of average elevation,average slope,raw material industrial density,and population density to the spatial differentiation of habitat quality are all above 0.40.The interactions of any two factors on habitat quality are enhanced.Areas with concentrated populations,rich industrial resources,and convenient transportation become low-value 退化的生态环境一直是全球资源型城市可持续发展的挑战。尽管此问题已经引起了学界的广泛关注,但从自然与人为因素相互作用的角度探讨资源型城市生境质量的空间分异格局及其影响机理的研究较少。本文以唐山市为例,基于综合生态系统服务价值和InVEST-HQ模型对生境质量进行评估,利用空间自相关识别唐山市生境质量的空间分异特征,并借助地理探测器模型和空间生产理论探讨唐山市生境质量空间分布差异的影响因素及其影响机理。结果表明:(1)2019年唐山市生境质量总值为3.45×10^(10)元,每公顷生境质量价值为24435.05元。唐山市生境质量值呈现出"南北偏热,中西偏冷"的分布格局。(2)县域尺度上迁西县生境质量最优,路北区生境质量最差;乡镇单元上上营乡生境质量均值最高,开平街道最低。(3)自然环境条件是影响唐山市生境质量空间分异的重要基础因素。城市化和工业化因素是唐山市生境质量空间分异的重要外在动力。平均海拔、平均坡度、原材料业密度和人口密度对生境质量空间分异的贡献均大于0.40。任意两因子对生境质量的交互作用均为增强。人口聚集、工业资源丰富、交通便利的区域成为生境质量低值区,景观格局优美、降雨充沛、气候舒适的区域成为生境质量高值区。空间生产理论可以用来解释生境质量空间分异的形成机理。
