Urban transformation is an inevitable trend for mining cities to achieve sustainable development. Analyzing the spatiotemporal evolution laws and driving mechanisms of mining cities is necessary for providing a scientific basis for their transformation. In this study, Jixi was taken as an example, which is a typical mining city in China. Based on geographic information system, various mathematical statistical analysis methods were used to quantitatively analyze the evolution pattern of mining cities. In addition, the driving mechanisms of land expansion in mining cities were examined further. The results showed that (1) the urban land in the mining city is mainly distributed in low-lying areas, and land expansion mainly occurred in flat areas. (2) Based on the distribution of mineral resources, the land use pattern of mining cities was scattered; with steady economic development, the urban spatial pattern tends to be compact. (3) The spatial pattern of mining cities is affected by natural, economic, and policy factors. The results reveal the spatiotemporal evolution law and driving mechanism of the patterns in mining cities, thereby providing a scientific basis for the sustainable development planning and land management of mining cities.
城市转型是矿业城市实现可持续发展的必然趋势。分析矿业城市的时空演变规律及驱动机制，对于为其转型提供科学依据具有重要意义。本研究以中国典型矿业城市鸡西为例，基于地理信息系统，运用多种数理统计分析方法对矿业城市的演变格局进行定量分析，并进一步探讨矿业城市土地扩张的驱动机制。结果表明：（1）矿业城市的城市用地主要分布在低洼地区，土地扩张主要发生在平坦地区；（2）基于矿产资源分布，矿业城市的土地利用格局较为分散，随着经济的稳定发展，城市空间格局趋于紧凑；（3）矿业城市的空间格局受自然、经济和政策因素的影响。研究结果揭示了矿业城市格局的时空演变规律及驱动机制，为矿业城市的可持续发展规划和土地管理提供了科学依据。
