摘　　要：快速的城镇化、工业化进程深刻地改变了资源型城市景观健康状态,对景观进行科学管护的重要性日渐凸显。本研究选择土地利用、坡度、高程等8个景观特征要素,使用二阶聚类和格式塔归档法对迁安市进行景观特征识别;在此基础上,利用“健康-影响-风险”模型构建资源型城市景观生态健康评价指标体系,以景观特征区域为评价单元,使用综合指数法计算景观健康综合指数,分析1995-2020年迁安市景观健康状态变化趋势。结果表明:(1)迁安市可分为17类景观特征类型和11类景观特征区域。1995-2020年间,乡村聚落景观、城镇景观、城镇工矿用地景观的景观健康等级以III级为主,其他景观特征区域的景观健康等级相对较高,为IV级;(2)1995-2020年,水域景观、乡村聚落景观、城镇工矿用地景观的景观健康综合指数呈增加趋势;其他景观特征区域的景观健康综合指数呈下降趋势;(3)以相关规划为依据,结合迁安市景观生态健康评价结果,按照“问题识别-重点优化”的思路,针对主要景观特征区域,即低海拔耕地景观、城镇工矿用地景观、城镇景观提出景观优化建议。The rapid urbanization and industrialization process have profoundly changed the health status of resource-based urban landscapes,and the importance of scientific management and protection of landscapes is becoming increasingly prominent.In this study,we selected 8 landscape character elements such as land use,slope,and elevation for analysis,and adpoted second-order clustering and Gestalt filing method to identify the landscape character of Qian'an.On this basis,a resource-based urban landscape ecological health assessment index system was constructed using the"health-impact-risk"model.The landscape character regions were used as assessment units,and the comprehensive index method was used to calculate the landscape health comprehensive index.The trend of landscape health status changes in Qian'an from 1995 to 2020 was analyzed.The results indicated that:(1)Qian'an can be divided into 17 landscape character types and 11 landscape character regions.From 1995 to 2020,the landscape health level of rural settlement landscapes,urban landscapes,and urban industrial and mining land landscapes was mainly level III,while the landscape health level of other landscape characteristic areas was relatively high,which was at level IV;(2)From 1995 to 2020,the landscape health comprehensive index of water landscape,rural settlement landscape,and urban industrial and mining land landscape showed an increasing trend.The comprehensive index of landscape health in other landscape characteristic regions showed a downward trend;(3)Based on relevant planning and combined with the results of landscape ecological health assessment in Qian'an,following the approach of"problem identification-key optimization",landscape management suggestions and strategies are proposed for the main landscape characteristic regions,namely low altitude cultivated land landscape,urban landscape,and urban industrial and mining land landscape.
