资源型城市景观特征识别及生态健康评价研究
Research on landscape character assessment and ecological health assessment of resource—based cities
摘要
Abstract
The rapid urbanization and industrialization process have profoundly changed the health status of resource-based urban landscapes,and the importance of scientific manage-ment and protection of landscapes is becoming increasingly prominent.In this study,we se-lected 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 charac-ter 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 char-acter 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 levelⅣ;(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 in-creasing 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 re-sults of landscape ecological health assessment in Qian'an,following the approach of"prob-lem 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.关键词
