Abstract

The study area lies in the lower estuary of Lagoa dos Patos in the city of Rio Grande (Lat/Long: 32°02’16.39”S/52°06’28.41’’W), Rio Grande do Sul state, Brazil, comprising a total area of approximately 280,000 hectares (ha). To select areas suitable for marine shrimp farming, data processing and digital modeling were conducted with the Idrisi Andes Edition® GIS software using freely available images. Additionally, the most commonly used criteria, socioeconomic factors, infrastructure and logistics, soil, climate, topography, and water availability, were used. To improve upon the obtained results from a classification based exclusively on the distinction between restricted and suitable areas for aquaculture, a suitability score for each criterion analyzed was created, and distances from suitable sites were measured. According to the suitability rating (prioritized from 1 to 4), 2,100 ha (24.01% of the area) were considered suitable with excellent conditions; 3,100 ha (34.80%) were considered good; 3,600 ha (40.37%) were marginally suitable; and, finally, a small fraction of 70 ha (0.82%), was considered acceptable but not recommended. This study has demonstrated the potential of GIS to support the selection of areas suitable for marine shrimp farming.

巴西南部海虾养殖的沿海规划和土地利用

研究区位于巴西南里约热内卢Grande州(Lat/Long: 32°02 ' 16.39 " S/52°06 ' 28.41 " W) Lagoa dos Patos市的下河口，总面积约为280,000公顷。为了选择适合海洋虾养殖的区域，使用Idrisi Andes Edition®GIS软件使用免费提供的图像进行数据处理和数字建模。此外，还使用了最常用的标准、社会经济因素、基础设施和物流、土壤、气候、地形和水的可用性。为了改进完全基于限制和适宜水产养殖区域区分的分类所获得的结果，为分析的每个标准创建了适宜性评分，并测量了与适宜地点的距离。根据适宜性等级(1 ~ 4级)，适宜区面积2100公顷(24.01%)，条件优良;3100公顷(34.80%)为良好;3600公顷(40.37%)勉强适宜;最后，70公顷的一小部分(0.82%)被认为是可以接受的，但不推荐。这项研究证明了地理信息系统在支持选择适合养殖海虾的地区方面的潜力。

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.
