The assessment of the spatiotemporal evolution of habitat quality caused by land use changes can provide a scientific basis for the ecological protection and green development of mining cities. Taking Yanshan County as an example of a typical mining city, this article discussed the spatial pattern and evolution characteristics of habitat quality in 2000 and 2018 based on the ArcGIS platform and the InVEST model. The conclusions are as below: from 2000 to 2018, the area of farmland and construction land changed the most in the study area. Among them, the area of farmland decreased by 3.48%, and the area of industrial and mining land and construction land increased by 53.25%. Areas of low, relatively low and high habitat quality expanded, and areas of medium and relatively high habitat quality shrank, which is closely related to the distribution of land use. The areas with high habitat degradation degrees appear around cities, mining areas and watersheds, while the areas with low habitat degradation degrees are mainly distributed in the southern woodland. The distribution of cold and hot spots in the habitat quality distribution of Yanshan County presents a pattern of “hot in the south and cold in the north”. The results are of great significance to the precise implementation of ecosystem management decisions in mining cities and the creation of a landscape pattern of “beautiful countrysides, green cities, and green mines”.

评估土地利用变化引起的生境质量时空演变可为矿业城市生态保护和绿色发展提供科学依据。本文以盐山县为例，基于ArcGIS平台和InVEST模型，探讨了2000年和2018年生境质量的空间格局和演化特征。结论如下：2000-2018年，研究区耕地和建设用地面积变化最大。其中，耕地面积下降3.48%，工矿用地和建设用地面积增长53.25%。栖息地质量低、相对低和高的区域扩大，栖息地质量中等和相对高的区域缩小，这与土地利用的分布密切相关。生境退化程度高的区域出现在城市、矿区和流域周边，而生境退化程度低的区域主要分布在南部林地。燕山县生境质量分布冷热点分布呈现“南热北冷”格局。研究结果对矿业城市生态系统管理决策的精准实施，打造“美丽乡村、绿色城市、绿色矿山”的景观格局具有重要意义。燕山县生境质量分布冷热点分布呈现“南热北冷”格局。研究结果对矿业城市生态系统管理决策的精准实施，打造“美丽乡村、绿色城市、绿色矿山”的景观格局具有重要意义。燕山县生境质量分布冷热点分布呈现“南热北冷”格局。研究结果对矿业城市生态系统管理决策的精准实施，打造“美丽乡村、绿色城市、绿色矿山”的景观格局具有重要意义。
