本研究使用Landsat卫星数据来论证哥伦比亚—厄瓜多尔部分边界23年间(1973～1996)土地覆被变化的速度和格局。人类定居给这两个国家带来了大量毁林。变化的卫星检测分析表明,边界哥伦比亚一侧年毁林速度相对高得多。另外,哥伦比亚一侧森林覆被在研究期间几乎损失了43%,而在厄瓜多尔一侧只损失了22%。研究发现,在边界的任何一侧,都不存在单一的毁林驱动因素;但得出结论:哥伦比亚一侧的毁林速度高可能是由于定居压力高、非法古柯种植加剧。卫星图像证明,在厄瓜多尔一侧,毁林格局反映出与石油勘探和开发有关的道路网络。

Touristic urbanization and greening of coastal dune fields:A long-term assessment of a temperate sandy barrier of Argentina

引用

Journal of Geographical sciences 2025年第1期35卷 206-230页

作者： GARZO Pedro andrés DADON José Roberto IsLA Federico Ignacio Instituto de Investigaciones Marinas y Costeras (IIMyC-CONICET/UNMDP) Instituto de Geología de Costas y del Cuaternario Dr.Enrique J.schnack (IGCC-CIC/UNMDP) Universidad de Buenos Aires Facultad de Arquitectura Dise?o y Urbanismo Centro de Investigaciones Gestión de Espacios Costeros (GEC-FADU/UBA) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET)

Dune barrier systems represent highly sought-after coastal landscapes for tourism and urban development around the world. However, a century ago, they were considered hazardous environments due to their great dynamic nature. As a result, stabilization practices were considered necessary. The systematic introduction of fast-growing exotic trees helped stabilize the sand, making it easier for tourism urbanization to take place, but also leading to erosion processes. This paper aims to assess long-term changes in vegetation cover over a large temperate barrier in Argentina. This complex region includes urban resorts, afforestation zones, and protected areas. A GIs-based geospatial analysis was conducted using a large satellite database(> 350 images), and the future evolution of the vegetation was modeled. The results revealed two primary spatiotemporal patterns associated with a gradual expansion of vegetation cover, accompanied by a concurrent reduction in sandy areas. In 1986, the dune area comprised 75% more surface than vegetation, whereas in 2021, it represented 60% less than vegetation. Furthermore, the 2050 scenario suggests a potential 40% reduction of dunes in certain areas. It is necessary to enhance management actions aimed at maintaining dune mobility and ensuring local and regional sediment balance. Long-term management strategies must focus on restoring native plant communities and controlling invasive species, and avoiding new dune fixation initiatives based on the introduction of exotic species.

Alzheimer’s disease(AD)is the most common neurodegenerative disorder characterized by slow and progressive decline of cognitive and memory *** only approximately 5%of the cases,AD is familial,as often predisposed by genetic mutations(Hoogmartens et al.,2021),while sporadic AD accounts for approximately 95%of the *** amyloid cascade hypothesis is one of the fundamental hypotheses put out to explain AD pathogenesis as dysregulated homeostasis of amyloid-β(Aβ)peptides that leads to the accumulation of Aβplaques in the parenchyma,an anatomical hallmark of AD.
