摘要:针对依靠煤炭工业发展形成的中小城镇在矿产资源枯竭后城市产业发展转型问题，以大雁镇和牙克石市建成区为研究对象，利用RS和GIS技术，对研究区2006年，2011年，2017年的遥感影像进行景观分类处理，选取6种景观格局指数进行计算，分析该区域多年的景观动态变化。结果表明：大雁镇和牙克石市主要建成区在矿业生产活动停止后城镇建设类景观面积扩大，景观优势度比重变大，交通线发达城区建设完整规范；生态类景观得到保护与发展，面积增加，景观生态类型增多；草地面积减少，但仍属于优势景观；城镇待建用地景观面积增大，景观优势度占比不断增加，城镇规划利用空间大。研究结果可协助矿业城市在经济转型过程中实现可持续发展。

Abstract:In response to the problem of industrial transition in small and medium-sized towns developed on the basis of coal industry after the depletion of mineral resources，taking the built-up areas of Dayan Town and Yakeshi City as research objects，Using RS and GIS technologies，the remote sensing images of the study area in 2006，2011，and 2017 were subjected to landscape classification.Six types of landscape pattern indices were selected for calculation to analyze the landscape dynamic changes in the area over the years.The results showed that after mining activities stopped，the urban construction landscape area and its dominance proportion in Dayan Town and Yakeshi City in main urban areas increased.The proportion of transportation lines also increased，and the urban construction became more complete and standardized. Ecological landscapes were protected and developed with increasing area and ecological types.Although grassland area decreased，it remained a dominant landscape. The area of urban land waiting for construction increased，and the dominance proportion of the landscape continued to increase，this resulted in a larger planning and utilization space.The research results could help mining cities achieve sustainable development in the process of economic transformation.
