Item Acesso aberto (Open Access) Análise das unidades de paisagem da microbacia do igarapé Moura, município de Castanhal (PA): subsídios para o planejamento/ordenamento territorial(Universidade Federal do Pará, 2013) ALVES, Leonardo Pinheiro; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714This study analyzed the landscape units of the Igarapé Moura micro-basin in the Municipality of Castanhal-PA, considering the structure and dynamics owing to the ability to support anthropogenic actions in order to aid the basin's territorial planning. To carry out this analysis, we have chosen the systemic interpretation method, based on General Systems Theory and the Complex Dynamical Systems Theory. The interpretation script comes from the following operating procedures: an integrated analysis of the physiographic features of the watershed (geology, relief units, hypsometric, slope, soil conditions and ground cover and use), mapping of the landscape structure (landscape units); analysis of the dynamics of landscape units (multitemporal mapping of vegetation cover and land use from satellite images from 1984, 1994 and 2010); delimitation of areas of stability / instability of the physical environment, identifying capable areas for agricultural crops, pasture and forestry, as well as areas unsuitable for agricultural use; delimitation of areas of legal incompatibility, and finally preparing the mapping using the indicated capacity. Based on analysis of the physiographic features of the watershed, it was possible to identify six landscape units: Geosystem of Hills and Law Plateaus with Productive Activities, Geosystems of Law Plateaus and Hills With Urbanized Areas, Geosystems of Low Plateaus with Productive Activities, Geosystem of Low Plateaus with Urbanized Areas, Geosystem of the Capoeiras over Hills, Low Plateaus and Law Plateaus e Geosystem of the Flooded Rainforests in Floodplains. Looking through the instability, the Basin predominantly presents areas with significant levels of instability, especially geosystems that feature human deeds. In contrast, areas with more stable conditions are characterized by areas where is possible to see a denser vegetative substrate, located in the Geosystem of the Capoeiras over Hills, Law Plateaus and Low Plateaus and in Geosystem of the Flooded Rainforests in Floodplains. In the analysis of agricultural suitability of the Basin's landscapes, it was found that its larger portion enables the use of technological development for farming, artificial grazing and forestry. In addition to these, there are also unsuitable areas for agricultural activities. Finally, it was established seven areas of recommended use in accordance with the support capacity of the landscape units of Igarapé Moura Basin: agricultural technology, mechanized agriculture, urban area, preservation, priority preservation, conservation/sustainable use and priority recovery. Therefore, from these analyzes, a need of using technical and scientific levels in agricultural production in the Basin was found, aimed at improving the management of different forms of landscape units and the need of preservation of secondary vegetation cover through techniques aimed at sustainable development linked to forest maintenance, essential for the territorial planning of this area.Item Acesso aberto (Open Access) Estrutura e fisiologia da paisagem da praia do Areião, Ilha de Mosqueiro (Belém-PA)(Universidade Federal do Pará, 2013-07-04) VIANA, Ivan Gomes da Silva; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714This study has guided the analysis on concept of landscape in systemic perspective and understand there’re elements that interact in complex ways. Areião Beach shows a peculiarity. Thus, the study was made to understand elements that act in southwestern part of the coastal zone of this island, where is located the search area. In one hand, physical elements are analyzed at landscape, such as waves action, wind, tides, vegetation and rainfall, in other hand, the influence of anthropogenic elements are analyzed such as the pier, the effluents and process of using and occupation. Nevertheless, some steps were followed to understand Areião Beach landscape elements in this study. The first step was to create a theoretical-conceptual reference in geography concepts, following the objectives of this work. There’s adopted the classification of Landscape Units proposed by Bertrand (1972). Later it was understood the structure of the landscape, showing the facts of study area on spatial distribution in maps. Four diferent parts were delimited at the beach. After, the seasonality was evidenced by the physiology of landscape and it was highlighted in the analysis guiding interpretations of data variability of morphology and granulometry, as well as their interactions with anthropogenic elements. At this time, the pier’s influence in landscape’s identified. It is believed that pier creates a buffer zone, where tidal action is attenuated to erosional processes that reach the beach. Furthermore, granulometric analysis and the degree of selection showed that there were two sediment transporting cell. The first before the pier, where are the profiles 1 and 2 was located. And the second one after pier, where profile 3, 4 and 5 were located. So Areião Beach was classificated in landscape units. The beach was rated on Geosssistema’s scale, being subdivided into geofacies Ie, IIa1, IIa2, IIa3, IIIe, IIIa, IVa and IVe. At each definition of geofacies we wanted to point, in a spatiotemporal scale of detail, the interrelationship between the physical and anthropogenic active in each landscape unit. The morphology and granulometri data were crossed with qualitative analysis developed through observations in locu to complete the definition.Item Acesso aberto (Open Access) Formas de relevo e dinâmica costeira em São Caetano de Odivelas (PA)(Universidade Federal do Pará, 2013-05-22) PICANÇO, Maria do Socorro Monteiro; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714The present research was conducted on the northern part of municipality of São Caetano de Odivelas (PA), which had as objectives identify the relief units, analyze the distribution of these units from the physiographic conditions, verify the variation of multitemporal position of the coastline, identify the geoindicators and analyze the consequences for the vegetation and the morphology that area of study. The methodological procedures of the research included the bibliographical survey and literature review, cartographic base survey and products from remote sensors; treatment and digital processing of orbital images, thematic mapping and field work. Among the morphological units, in this area of study, are the tabuleiros that totals of 52.7 km ² and are located in the center of this area of study, in the shape of isolated blocks with a wavy soft relief, where the altimetry ranges from 6 to 30 meters; The plains of muddy tidal add up to 95.9 km ² and will position themselves as sites parallel to the coastline and along the lower course of rivers, have a flat topography, in which his altimetry goes 2 to 6 meters; muddy banks of intertidal have 7.3 km ², are positioned so as planes parallel to the coastline, with slightly angled relief that goes 0 to 2 meters; the sand ridges subatual add up to 2.2 km ² and are positioned in the shape of arrows arranged as meaning of the present coastline, with flat topography, with a altimetry 6 to 12 meters; alluvial plains have 10.7 km ² and are situated in contact with mangrove areas and along some river channels, with flat topography, above 6 meters; alluvial plains presenting species of Avicennia sp. have 1.1 km ², feature a flat topography that goes 2 to 6 meters and are found the interior plains of muddy tidal; alluvial plains with vegetation fields add up to 4.4 km ², are located shaped places of the narrow valley floors with a flat topography ranges from 4 to 10 meters; the sandy bars have 17.3 km ², are located as deposits elongated in the sense of the mouths of estuaries and feature a flat topography, which ranges from 0 to 2 meters. The geomorphological indicators identified are the advance and retreat of the coastline; the emergence and growth of sandy bars; approach and retraction of sandy bars in relation to the coastline; the biological indicators relates to formation and destruction of neossolos mangrove soil; the increase of mangrove area and development of the standard "Escada"; reduction mangrove area and pattern formation "Paliteiro". The morphological changes can be classified in their majority as acrecionais because in 24 years there was an increase in mangrove area of 3.85 km ², which responsible for 4.19% of the total area plus in addition to have occurred in this period, installing two new islands, the Nova and Peruru. The dynamic that occurs in this municipality cause changes in soil and morphology due to installation of neossolos and formation of mangrove ecosystem, besides the occurrence of patterns "Escada" and "Paliteiro".Item Acesso aberto (Open Access) Impactos da ocupação urbana e qualidade das águas superficiais na microbacia da Va-de-Cães (Belém/PA)(Universidade Federal do Pará, 2007) MARANHÃO, Romero de Albuquerque; SIQUEIRA, Gilmar Wanzeller; http://lattes.cnpq.br/3145792580729701; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714The hidrografic basin of Val-de-Cães, with 10,10Km2, situated in the portion north of the City of Belém, presents as characteristic the dense urban occupation, represented for clandestine occupations, joint residential and for institucional areas. The present study it analyzes the impacts proceeding for the main forms from occupation and use of the basin of Val-de-Cães, using as indicating the quality of superficial waters of the hidric body. The analyses of waters had been carried through in two periods, rainy (February) and a other dry one (August), being determined the following parameters: turbidez, condutividade, color, pH, Dissolved Oxygen, nitrogenados components, temperature, Demand Biochemist of Oxygen, metals, oils and greases and total and fecais coliformes. The water of the narrow river disclosed values raised in downstream of the narrow river, possibly for the direct influence of the bay one of the Guajará, for pH, oils and greases, coliformes and Demand Biochemist of Oxygen. In the spring the parameters of total coliformes and Demand Biochemist of Oxygen present values that are considered raised in relation to the too much points of collection, but are the palafitas place that presents considerable number in the neighborhoods and little vegetation. The presence of effluent domestic servants and sewers is portraied mainly by the amount of coliformes, oils and greases, turbidez and text of match in the samples collected in both the periods and for the great number of dump points that increase to each day.Item Acesso aberto (Open Access) Unidades de relevo em zona costeira estuarina: municípios de Colares e Santo Antônio do Tauá(Universidade Federal do Pará, 2007-08-20) BARBOSA, Estêvão José da Silva; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714This work identified and argued the geomorphic units (relief) of Colares and Santo Antônio do Tauá municipalities, State of Pará, Brazil. It has Geomorphology as subject. The studied area is located in eastern portion of Amazon River Estuary (“Golfão Marajoara”), northeast of Marajó bay, at estuarine coastal zone. In this study was used: bibliography, maps, remote sensing data and work fields. The analysis was made by two scales. First Scale is represented by the Amazonian Coastal Zone, which shows low altitude, sedimentary lithology, macrotidal tidal range, tropical and wet climate and stronger river discharges. This regional coast was produced by relative sea-level fluctuations, climatic changes, and tectonic dynamics occurred throughout Late Cenozoic. Eastern portion of Amazon River estuary is formed by Pará River Estuary – Marajó Bay, a typical tidal river or river-dominated estuary, although it has tidal influence. River discharge is main component of the estuarine dynamics, sedimentary constitution and biota organization. Pará River Estuary is a coastal environment with less energy of waves and littoral currents than the shore of Northeast Pará. In the second scale, were identified eight geomorphic units: sandy estuarine channel; tidal mud bank; tidal mud flat; estuarine beach; dune-beach ridge; tidal influence alluvial plain; alluvial plain; plateau. Only plateau is a erosive relief unit. The research also deals spatial distribution of these geomorphic units, in two sectors. Sector 1 is located in western portion of studied area. It is largely influenced by tides, and has different depositional relief units. The major geomorphic unit is tidal influence alluvial plain, which results of transition between marine and alluvial factors. Freshweater swampy formations followed mangroves toward landward due to reduced saline influence in the channels. Sedimentary distribution is marked by sand bottom channels, and mud deposits in the margins. Beachs are shorts, commonly covered by mud sets because less wave energy and crucial role of tidal current, discharges action in the coastal dynamics. Dune-beach ridges localized landward coastal plain are the indicative its progression. In this sector, plateaus are discontinuous due to erosion and deposition by tidal, flow channels and rains. Sector 2, localized in eastern portion of studied area, has no tidal influence. It shows a relief little compartmented, with large plateaus dissected by rivers. Fluvial action formed valleys with narrow alluvial plains, which demonstrated a greatest erosive surface in the sector 2.
