La connaissance détaillée et le suivi de la végétation urbaine représentent un enjeu important, tant pour les scientifiques qui étudient les relations paysage-écosystème, que pour les gestionnaires qui sont chargés de l'entretien et de la gestion de la végétation. Le principal objectif de cette thèse est d'évaluer l'intérêt des images à THRS pour cartographier la végétation en ville. Plus précisément, elle vise à évaluer le potentiel des images THRS sur trois composantes : la résolution spatiale, la résolution spectrale et l'altimétrie. Pour cela, nous avons traité plusieurs types de données optiques THRS acquises sur la Ville de Rennes et le Site des Prairies Saint-Martin : des images 2D multispectrales et superspectrales, des images multispectrales 2,5D et des données 3D acquises par un LiDAR bi-spectral. Dans un premier temps, nous avons évalué l'intérêt d'utiliser des images THRS 2D multispectrales pour identifier et caractériser la végétation et des images THRS super spectrales afin d'identifier les espèces végétales. Dans un second temps, nous avons évalué l'apport de données multispectrales THRS 2,5D et 3D pour cartographier les formes de végétation en milieu urbain en utilisant des variables spectrales, contextuelles et de hauteur. Dans un troisième temps, avons cherché à évaluer l'impact, de l'intégration des informations sur la végétation dérivées de données de télédétection THRS dans deux modèles environnementaux, un permettant d'étudier la relation paysage-biodiversité, l'autre la relation paysage- îlot de chaleur urbain / Abstract: Detailed knowledge and monitoring of urban vegetation is an important issue, both for scientists studying landscape-ecosystems relationships, and for the managers who are in charge of the vegetation management. The main objective of this thesis is to evaluate the interest of THRS images to map urban vegetation. More specifically, it aims to evaluate the potential of THRS images on three components: spatial resolution, spectral resolution and altimetry. For this purpose, we processed several types of THRS optical data acquired on the City of Rennes and the Prairies Saint-Martin Site: multispectral and superspectral 2D images, 2.5D multispectral images and 3D data acquired with a bi-spectral LiDAR. Firstly, we assessed the interest of using 2D multispectral THRS images to identify and characterize vegetation and superspectral THRS images to discriminate plant species. Secondly, we assessed the contribution of THRS 2.5D and 3D multispectral data to map vegetation patterns in urban areas using spectral, contextual and height variables. Thirdly, we sought to evaluate the impact, of the integration of vegetation information derived from THRS remote sensing data into two environmental models, one to study the landscape-biodiversity relationship, the other to analyze the landscape- urban cool island relationship.

This research investigated the water use of different plant types in urban landscapes, nitrogen (N) and water transport in turf, and potential N leaching from urban landscapes to ground water. In the first study, three landscape treatments integrating different types of plants—woody, herbaceous perennial, turf—and putative water use classifications—Mesic, Mixed, Xeric—were grown in large drainage lysimeters. Each landscape plot was divided into woody, turf, and herbaceous perennial plant hydrozones and irrigated for optimum water status over two years, with water use measured using a water balance approach. For woody plants and herbaceous perennials, canopy cover, rather than plant type or water use classification, was the key determinant of water use relative to reference evapotranspiration (ETo) under well-watered conditions. For turf, monthly evapotranspiration (ETa) followed a trend linearly related to ETo. In the second study, water transport parameters were calibrated using an inverse simulation with Kentucky bluegrass (KBG). Subsequently, those parameters were applied to simulate water use by tall fescue (TF) and buffalograss (BG) turfgrasses using numerical modeling (Hydrus-1D). By using the calibrated soil hydraulic parameters obtained from the water transport simulation, N transport and transformation was modeled with Hydrus- 1D under different irrigation rates and different fertilization rates. Different soil texture scenarios were also simulated to demonstrate the influence of soil texture on N leaching. In the third study, the simulated N-leaching from different soil textures was integrated into a Geographic Information System (GIS) approach to estimate NO3-N leaching mass from urban turf areas. Nitrate-N leaching risks to ground water under overirrigation and overfertilization scenarios and efficient irrigation and fertilization scenarios were estimated. The results showed improvement of turf irrigation and fertilization management may decrease N-leaching significantly and greatly decrease the risk of ground water being contaminated by NO3-N leaching in the Salt Lake Valley.

[pt] Esta dissertação analisa, a partir da trilogia cinematográfica de Batman (2005-2012), o modo como os procedimentos expressivos elaborados nas imagens constroem (ou não) a possibilidade de emancipação do espaço urbano. Inseridos no contexto pós 11 de setembro, os três filmes dialogam com o lastro iconológico da Guerra ao Terror: figuras sem-rosto, duplos, múltiplos, anônimos, imagens especulares; e ao centro das disputas, a metrópole de Gotham. O custo necessário , entretanto, para a salvação de Gotham por Batman parece ser o monopólio tanto da cidade quanto da imagem da cidade: um monopólio que serve de blindagem contra os efeitos caleidoscópicos do terror. A paisagem urbana (amálgama entre a urbe e sua imagem) se torna portanto meio privilegiado de análise. E eis a centralidade do segundo filme da trilogia na discussão que se propõe: o ataque iconoclasta do Coringa, por meio do jogo e do riso, profana o monopólio (da verdade , do bem , da ordem e da imagem) instituído pelo homem morcego. Com a invasão de uma imagem outra por entre as visibilidades do filme, rompe-se o unívoco e com ele o monopólio sobre a cidade e suas representações. / [en] This research examines, from the Batman cinematographic trilogy (2005- 2012), the way in which expressive procedures elaborated in the images can build (or not) the possibility of the urban space s emancipation. Inserted in the post 9/11 context, the three movies dialogue with the iconological traces of the War on Terror: faceless figures, doubles, multiples, anonymous, specular images; and at the centre of the dispute, Gotham metropolis. The necessary cost, however, for the salvation of Gotham by Batman seems to be the monopoly of the city as well as of the city s image: a monopoly that serves as a shield against the kaleidoscopic effects of terror. The urban landscape (an amalgam between the city and its image) thus becomes a privileged medium of analysis. And hence the centrality of the Trilogy s second movie in the proposed discussion: the iconoclast attack of the Joker, through play and laughter, desecrates the monopoly (of truth , good , order , and image) instituted by Batman. With the invasion of a different image between the movie’s visibilities, the univocal disrupts itself, and with it the monopoly over Gotham and its representation.

Esta tese debate a produção do espaço urbano a partir de duas vertentes, as condições biofísicas do território e a sociedade, com a finalidade de buscar alternativas para um desenvolvimento que compatibilize meio ambiente e cultura. Assim, define os princípios e conceitos em que se fundamenta o planejamento urbano ecológico a partir de (MCHARG, Ian L., 2000), (HOUGH, Michael, 1998), (SPIRN, Anne Whiston, 1995), (SANTOS, Milton, 1996 e 1997), (PALOMO, Pedro J. Salvador, 2003), (PELLEGRINO, Paulo R. M., 1995), e (BENEDDICT, Mark A., MCMAHON, Edward T., 2006); delineia enfrentamentos distintos dos que vêm sendo propostos e que têm materializado sérios problemas ambientais, sociais e de espaços e relações humanas de segregação nas cidades; focaliza em Goiânia, uma cidade planejada, a leitura de como o meio ambiente, os projetos e as pessoas em sua vivência ordinária vão compondo uma nova paisagem; e analisa um ambiente específico, a unidade de conservação Morro do Mendanha, que permite a interpretação dos conflitos e oportunidades que podem determinar valores alternativos capazes de assegurar o equilíbrio entre desenvolvimento urbano e conservação ambiental, porque permite processos de ocupação antrópicos com preservação de características ambientais relevantes, conectando pessoas e lugares. Por fim, apresenta um projeto de Infraestrutura verde aplicado à APA do Morro do Mendanha como uma estratégia capaz de estabelecer a retomada de um desenvolvimento social autóctone e em equilíbrio com as características biofísicas do lugar. / This thesis discusses the production of urban space from two aspects, the territory biophysical conditions and the community, with the purpose of searching for alternatives of development which promotes compatibility between the environment and culture. Thus, it defines the principles and concepts on which the ecological urban planning is fundamented, based on MCHARG, Ian L. (2000), HOUGH, Michael (1998), SPIRN, Anne Whiston (1995), SANTOS, Milton (1996 e 1997), PALOMO, Pedro J. Salvador (2003), PELLEGRINO, Paulo R. M. (1995), BENEDICT, Mark A., MCMAHON, Edward T. (2006); it outlines efforts that are distinct from those which have been proposed and that have caused serious environmental and social problems, as well as segregation in the human relations in the cities; it focuses on Goiânia, a planned city, the reading of how the environment, the projects and the people, in their ordinary life, go on composing a new landscape; and it analyzes a determined environment, a unit of conservation called Mendanha Hill, allowing the interpretation of the conflicts and opportunities that may determine alternative values capable of assuring the balance between the urban development and the environmental conservation, because it allows processes of anthropic occupation with the preservation of relevant environmental characteristics, connecting people and places. Eventually, it presents a green infrastructure project applied to the APA of Mendanha Hill as a strategy capable of establishing the retaking of an autochtonous social development and in balance with the biophysical characteristics of the place.
