Abstract
[Objective]To thoroughly analyze the spatiotemporal heterogeneity characteristics of land use and reveal the dynamic response mechanism of ecological issues in the land use process.[Method]This study focuses on Anshan,a typical resource-based city.By utilizing the data from five phases of the land use change surveys from 2000 to 2020 and applying the land use dynamic degree model,it conducts an in-depth analysis of the dynamic change characteristics of land use in Anshan and its impacts on the ecological pattern,proposes corresponding policies.[Result]Land use types in the study area mainly are forestland,cultivated land,and construction land.The land use pattern in Ans-han has undergone significant changes.Construction land has shown a rapid and large-scale expansion trend,becoming the key factor driving the transformation of other land use types,which has affected the stability of the ecological pattern and the service functions of the ecosystem.Based on this,this study proposes countermeasures such as comprehensively promoting the ecological restoration of the agricultural space in the Liao River Plain in the northwest,constructing a high-quality development ecological space in the urban area of the central Anshan-Haicheng Economic Belt,and creating an ecological security pattern in the southeast mountainous forest-mining composite area.[Conclusion]The re-search findings not only provide a scientific basis for the optimal allocation of land space and ecological restoration in Anshan but also offer ref-erences for land use and ecological protection in similar resource-based cities.关键词
