摘要
研究区域土地利用与景观格局的动态变化,为南京市实现土地资源的合理利用与可持续发展提供有力支持。基于南京市2023年、2024年的土地利用数据,采用土地利用动态度、景观指数分析等方法,分析南京市2023—2024年土地利用及景观格局的动态变化。结果表明:(1)南京市土地利用结构呈现多元化特征,表现为林地占比最高,其次依次为建设用地、耕地和水域。(2)整体上土地利用程度较高,建设用地、未利用地占比增加。(3)受城镇化发展的影响,建设用地呈现显著扩张趋势,而林地与草地资源则持续流失。南京市在2023—2024年间土地利用格局发生显著变化,各地类转换频繁且强度较大,导致区域景观格局呈现明显的破碎化趋势。
Studying the dynamic changes in land use and landscape patterns provides strong support for the rational utilization of land resources and sustainable development in Nanjing.Based on land use data from 2023 and 2024,this study employed methods such as the dynamic degree of land use change and landscape index analysis to explore the spatiotemporal evolution of land use and landscape patterns in Nanjing during the period 2023—2024.The results indicate the following:(1)The land use structure in Nanjing exhibits a diversified characteristic,with forestland having the largest proportion,followed by construction land,cropland,and water bodies.(2)Overall,the level of land use is relatively high,with an increasing share of construction land and unused land.(3)Influenced by urbanization,construction land has expanded significantly,while forestland and grassland resources have experienced continuous loss.From 2023 to 2024,significant changes occurred in Nanjing’s land use pattern,with frequent and intense land use class transitions,leading to a marked fragmentation trend in the regional landscape pattern.
