In this context, this research aims to conduct an integrated geoenvironmental analysis of the Gandu River sub-basin, located in the municipalities of Gandu, Nova Ibiá, and Wenceslau Guimarães, in the state of Bahia, Brazil, within the phytogeographic domain of the Atlantic Forest. The investigation is based on a systemic approach, the geosystem perspective, and the principles of Landscape Ecology, considering the relationships between natural elements and forms of land use and territorial occupation. The methodological procedures involved bibliographic research, cartographic analysis, geoprocessing techniques in a GIS environment, and the preparation of thematic maps related to location, geology, geomorphology, hypsometry, slope, pedology, drainage network, land use and land cover, and the Normalized Difference Vegetation Index (NDVI). The results show that the environmental dynamics of the sub-basin are directly related to geological, geomorphological, pedological, and hydrological characteristics, which influence infiltration processes, surface runoff, and the distribution of vegetation cover. A predominance of areas associated with secondary vegetation and agroforestry systems was observed, especially the cacao-cabruca system, which is important for maintaining regional ecological connectivity. However, landscape fragmentation resulting from the expansion of agricultural and livestock activities and changes in land use represents a threat to biodiversity conservation and the stability of environmental systems. Therefore, integrated geoenvironmental analysis is a fundamental tool for supporting land-use planning strategies, water resource conservation, recovery of degraded areas, and the implementation of ecological corridors in the context of the Atlantic Forest of Bahia.","流域是综合环境研究的基本单元，因其代表了物理、生物和社会经济组分之间建立相互依存关系、塑造景观组织与功能的复杂系统。在此背景下，本研究旨在对位于巴西巴伊亚州甘杜、新伊比亚和文塞斯劳·吉马良斯市境内、地处大西洋森林植物地理区的甘杜河子流域进行综合地质环境分析。调查基于系统方法、地质系统视角和景观生态学原理，考量自然要素与土地利用及领土占用形式之间的关系。方法程序包括文献研究、制图分析、GIS环境下的地理处理技术，以及编制与位置、地质、地貌、高程、坡度、土壤、水系网络、土地利用与土地覆盖、归一化植被指数（NDVI）相关的专题地图。结果表明，子流域的环境动态与地质、地貌、土壤和水文特征直接相关，这些特征影响入渗过程、地表径流和植被覆盖分布。观测到与次生植被和农林复合系统相关的区域占主导地位，尤其是可可-卡布鲁卡系统，其对维持区域生态连通性具有重要意义。然而，农业和畜牧业活动扩张及土地利用变化导致的景观破碎化，对生物多样性保护和环境系统稳定性构成威胁。因此，综合地质环境分析是支持土地利用规划策略、水资源保护、退化区域恢复以及巴伊亚大西洋森林背景下生态廊道实施的基础工具。",null,"DELOS Desarrollo Local Sostenible","2026-09-11T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"巴西流域地质环境与景观生态研究，属自然地理与生态保护范畴，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],"生态保护","遥感监测","土地利用","流域治理","10.55905\u002Frdelosv19.n86-003",{"doi":25,"openalex_id":27,"authors":28,"venue":10,"cited_by_count":15,"oa_url":34,"card":35,"direction":39,"ingested_from":41},"W7212359574",[29,31],{"name":30,"orcid":9},"Ariel Moura Vilas Boas",{"name":32,"orcid":33},"Marcelo Araújo da Nóbrega","https:\u002F\u002Forcid.org\u002F0000-0002-8532-0630","https:\u002F\u002Fojs.revistadelos.com\u002Fojs\u002Findex.php\u002Fdelos\u002Farticle\u002Fdownload\u002F10122\u002F5532",{"tldr":36,"method":37,"finding":38,"direction":39,"opportunity":40},"对巴西Gandu河子流域进行综合地质环境分析，评估景观、水资源与大西洋森林保护的关系。","系统方法与景观生态学视角，结合GIS空间分析、专题制图及NDVI。","次生植被与可可农林系统维持生态连通性，但农牧扩张导致景观破碎化威胁保护。","农业遥感与作物表型","可结合多时相遥感与景观指数，量化农林复合系统对流域水文与连通性的动态影响。","openalex","2026-09-14T23:30:27.425323Z"]
