We used a multitemporal approach with aerial photographs from 1976 (FAB-DRM) and high-resolution satellite images from 2003, 2013, and 2022 obtained from Google Earth Pro. The data were processed through georeferencing, manual vectorization, and classification into nine (9) land use classes based on the MapBiomas Collection 8 classification legend. The results show a continuous expansion of urban areas throughout the period analyzed, particularly in environmentally sensitive areas near the margins of the lagoon system, leading to the suppression of riparian vegetation and increased pressure on the aquatic system. Although forest cover has increased in recent years, this change is mainly associated with the regeneration of secondary vegetation rather than effective ecological restoration. The ITA value of 5.292 classifies the watershed as degraded, reflecting high anthropogenic alteration. These findings highlight the need to combine spatial indicators with environmental management strategies to support urban planning and ecosystem conservation. The proposed approach provides a robust framework for monitoring anthropogenic impacts on coastal lagoon systems and supports decision-making for sustainable watershed management.","本研究利用遥感与地理信息系统，对巴西里约热内卢州尼泰罗伊市皮拉蒂宁加泻湖系统流域的土地利用变化进行了多时相分析，并采用人类改造指数（Anthropic Transformation Index, ATI）评估了人为压力。研究采用多时相方法，使用了1976年的航空照片（FAB-DRM）以及2003年、2013年和2022年从Google Earth Pro获取的高分辨率卫星影像。数据经地理配准、人工矢量化，并依据MapBiomas第8版分类图例划分为九（9）类土地利用类型。结果表明，在整个分析时期内，城市区域持续扩张，尤其是在泻湖系统边缘附近的环境敏感区域，导致河岸植被遭到破坏，水生系统承受的压力加剧。尽管近年来森林覆盖有所增加，但这一变化主要与次生植被的再生有关，而非有效的生态恢复。ATI值为5.292，将该流域归类为退化状态，反映出较高的人为改造程度。这些发现凸显了将空间指标与环境管理策略相结合以支持城市规划和生态系统保护的必要性。所提出的方法为监测沿海泻湖系统的人为影响提供了稳健框架，并为可持续流域管理决策提供了支持。",null,"Sociedade & natureza","2026-09-08T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究聚焦巴西沿海潟湖流域土地利用与人类活动压力评估，属城市生态与遥感领域，与三农、农业信息化、智慧农业无直接关联，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23,24],"遥感监测","土地利用变化","流域生态","人居环境压力","10.14393\u002Fsn-v38-2026-81975",{"doi":25,"openalex_id":27,"authors":28,"venue":10,"cited_by_count":15,"oa_url":38,"card":39,"direction":43,"ingested_from":45},"W7211972914",[29,32,35],{"name":30,"orcid":31},"Minércia Job Macamo","https:\u002F\u002Forcid.org\u002F0009-0002-8955-0705",{"name":33,"orcid":34},"Braian de Oliveira Salvador","https:\u002F\u002Forcid.org\u002F0009-0006-0514-3694",{"name":36,"orcid":37},"Fábio Ferreira Dias","https:\u002F\u002Forcid.org\u002F0000-0003-2078-7405","https:\u002F\u002Fseer.ufu.br\u002Findex.php\u002Fsociedadenatureza\u002Farticle\u002Fdownload\u002F81975\u002F44391",{"tldr":40,"method":41,"finding":42,"direction":43,"opportunity":44},"基于多时相遥感评估巴西Piratininga泻湖流域土地利用变化与人为压力。","1976年航拍与2003-2022年高分卫星影像，地理配准、矢量化并分9类计算A","城市持续扩张侵占敏感区，森林增加多为次生恢复，ATI=5.292属退化，人为扰动高。","农业遥感与作物表型","可将ATI与流域生态服务、水质监测耦合，构建沿海流域人为压力预警与规划决策模型。","openalex","2026-09-10T23:30:30.399094Z"]
