摘要

南部沙质温带屏障的旅游业历来是阿根廷布宜诺斯艾利斯沿海发展的驱动力之一。这一过程伴随着沙丘固定和随后的城市化，始于20世纪30年代，当时没有海岸管理政策，造成了一些环境问题。本工作旨在分析两个沙丘造林项目的历史发展，目的是描述它们的主要环境问题。这些项目几乎同时开始，目前处于完全不同的发展水平。为此，对文献和相关立法进行了审查，使我们能够对其进行定性并进行比较。同时，旨在提出新的沙丘固定策略。这些植树造林项目的特点之一是由两兄弟实施：卡洛斯和埃内斯托·盖塞尔。卡洛斯发起了一项植树造林活动，导致了盖塞尔别墅的扩张。这座城市达到了城市发展的历史记录，实际上它是阿根廷最受欢迎的度假胜地之一。埃内斯托在一个更受限制的沙丘地上创建了Dunamar，目前它的发展阶段明显低于Villa Gesell。海岸侵蚀、地表径流增加、前沙丘面积减少和原生沙丘植被更替是一些已报道的问题。目前，在不同的沙丘稳定战略下，有一些扩大这些村庄城市面积的项目。尽管它们的影响已被广泛记录，但他们建议固定在快速生长的外来物种身上。这项工作提出了通过与大约一个世纪前沙丘原始景观相对应的本土物种进行植被重建。为此，必须在沿海综合管理的框架内考虑到某些方面。

Environmental evolution of coastal afforestations: management strategies for dune fixation in the sandy barriers of Buenos Aires, Argentina

Tourism in the southern sandy temperate barriers has historically been one of the drivers of coastal development in Buenos Aires, Argentina. This process, which has been accompanied by dune fixation and a subsequent urbanization, began in the 1930s and occurred in the absence of coastal management policies causing several environmental problems. This work aims to analyze the historical development of two dune afforestation projects with the objective of characterizing their main environmental issues. These projects, which started almost simultaneously, are currently at completely different levels of development. For this purpose, a literature and relevant legislation review was carried out, allowing us to characterize them and generate comparisons. At the same time, it is intended to propose new strategies for dune fixation. One of the peculiarities of these afforestation projects is that two brothers carried them out: Carlos and Ernesto Gesell. Carlos initiated an afforestation that led to the sprawl of Villa Gesell. This city reached historical records of urban growth and it is actually one of the most popular bathing resorts of Argentina. Ernesto founded Dunamar on a more restricted dune field and it is currently at a significantly lower stage of development than Villa Gesell. Coastal erosion, surface runoff increase, decrease of foredune areas and replacement of native dune vegetation are some of the reported problems. Currently, there are projects for the expansion of the urban area of these villages under different strategies for dune stabilization. Although their effects have been extensively documented, they propose fixations with fast-growing exotic species. This work proposes the revegetation by means of native species corresponding to the original landscape of the dunes of about a century ago. To this end, certain aspects must be taken into account within the framework of integrated coastal management.

期刊介绍： Journal of Integrated Coastal Zone Management / Revista de Gestão Costeira Integrada is a peer-reviewed international journal that publishes articles dealing with all the subjects related to coastal zones and their management, namely focused on coastal oceanography (physical, geological, chemical, biological), engineering, economy, sedimentology, sociology, ecology, history, pollution, laws, biology, anthropology, chemistry, politics, etc. Published papers present results from both fundamental as well as applied, or directed research. Emphasis is given to results on interdisciplinary contributions, on management tools and techniques, on innovative methodological or technical developments, on items with wide general applicability, and on local or regional experiments that can be a source of inspirations to other regions. Journal of Integrated Coastal Zone Management is focused on coastal environments what means that embraces a wide area that extends from an indefinite distance inland to an indefinite limit seaward. Paleoenvironments, ancient shorelines, historical occupation, diachronically analysis and legislation evolution are some subjects considered to fall within the purview of the journal as well.
