“…For instance, less air pollution, smaller rainfall patterns, and cooler temperatures are associated with improvements in space aggregation, increasing the large sized green space patch. These results are similar to the research findings by Beatley [9], Jo [10], Yang et al [11], Shin and Le [15], Herb et al [16], and Leuzinger et al [17]. However, they didn't discuss the patterns of green space, they only emphasized the total areas of green space.…”

“…Green spaces are semi-natural areas [7] that not only have the environmental function of blocking noise [8], reducing carbon emissions and air pollution [9][10][11][12], conserving water and soil [13,14], adjusting the microclimate and moderating temperatures [12,[15][16][17][18][19], but also have the ecological functions of recovering fertility, preserving ecologically sensitive areas, providing the habitat and feeding spaces for various species [20,21], and stabilizing ecological systems [22]. Moreover, green space has the landscape functions of buffering interferential land use while enhancing environmental beauty and visual aesthetics.…”

Abstract:In order to achieve a sustainable urban environment, the increase of green space areas is commonly used as a planning tool and adaptation strategy to combat environmental impacts resulting from global climate change and urbanization. Therefore, it is important to understand the change of green space areas and the derived impacts from the change. This research firstly applied space analysis and landscape ecology metrics to analyze the structure change of the pattern of green space area within the Taipei Metropolitan Area. Then, partial least squares were used to identify the consequences on microclimate and air pollution pattern caused by the changing pattern of green space areas within the districts of the Taipei Metropolitan Area. According to the analytical results, the green space area within Taipei Metropolitan Areas has decreased 1.19% from 1995 to 2007, but 93.19% of the green space areas have been kept for their original purposes. Next, from the landscape ecology metrics analysis, in suburban areas the linkages, pattern parameters, and space aggregation are all improving, and the fragmentation measure is also decreasing, but shape is becoming more complex. However, due to intensive land development in the city core, the pattern has becomes severely fragmented and decentralized causing the measures of the linkages and pattern parameters to decrease. The results from structural equation modeling indicate that the changing pattern of green space areas has great influences on air pollution and microclimate patterns. For instance, less air pollution, smaller rainfall patterns and cooler temperatures are associated with improvement in space aggregation, increasing the larger sized green space patch.

“…The heat flux resulting from an algebraic summation of the listed fluxes qcond is transported into the ground (mainly by conduction) or in the opposite direction, depending on its minus/plus sign. The heat balance on the surface of the ground taking into account convection, radiation, and moisture evaporation has the following form [13][14][15][16][17][18][19][20][21]:…”

Methods for the calculation of the undisturbed ground temperature (UGT) are presented. Heat fluxes occurring on the surface of the ground and their influence on the UGT are described. Correlation equations for the calculation of the undisturbed ground temperature based on the meteorological data averaged in the yearly cycle are proposed. These equations are of a semi-empirical character and they are based on the heat flux balance. The determined coefficients of these equations, particularly the convection heat transfer coefficient, are consistent with the values specified by other methods.

“…Para Liu et al (2006), a temperatura da superfície pode ser um parâmetro chave para diversos estudos do meio ambiente. Herb et al (2008) desenvolveram um modelo para determinação da temperatura da superfície visando a identificação dos diversos usos e cobertura da superfí-cie, o qual pode ser usado para diferenciar mudanças na superfície. A avaliação de dados históricos da precipitação, segundo Souza et al (2004), e da evapotranspiração também pode auxiliar nesta identificação e em sua quantificação (Basstiaansen, 1998;Souza et al, 2004;UN, 2001).…”

RESUMOO estudo de parâmetros biofísicos como o Índice de Vegetação da Diferença Normalizada (NDVI), albedo e temperatura da superfície (LST), aplicado a ecossistemas, tem sido relevante para o entendimento de mudanças relacionadas à degradação do meio ambiente. Algumas alterações que provocam desequilíbrio de interações ecológicas em ecossistemas, como o desmatamento, a mineração, a agricultura inadequada e o superpastejo, entre outros, estão interrelacionadas. Para avaliação de mudanças temporais relacionadas à degradação do ecossistema caatinga obtiveram-se as imagens da diferença de três parâmetros: NDVI, albedo e temperatura da superfície, para os anos de 1985 e 2001 (estação seca), utilizando-se imagens TM. Este estudo foi aplicado à bacia do rio Brígida onde há uma exploração intensa dos recursos naturais, em que os resultados mostram aumento na temperatura da superfície, diminuição do NDVI e pouca variação no albedo da superfície evidenciando, assim, que entre os anos de 1985 e 2001 houve avanço na degradação dos recursos naturais, nesta bacia.Palavras-chave: temperatura da superfície, albedo, índice de vagetação, degradação da caatinga, modelagem de dados Biophysical parameters in the detection of changes in soil cover and use in watersheds ABSTRACTThe study of biophysical parameters such as NDVI, albedo and surface temperature has been reported as important for the understanding of land degradation changes of ecosystems. Degradation in ecosystems is related to the inadequate use of the environmental resources including deforestation, mining, inadequate agriculture, overgrazing, among others, that cause imbalance of ecological interactions. For multitemporal evaluation of changes related to the degradation of the 'caatinga' ecosystem three parameters were used with TM images: NDVI, albedo and surface temperature, in two different dates, 1985 and 2001 (dry season). This study was applied in the Brígida river basin where there is a great intensification in the exploration of the natural resources. The results show an increase in the surface temperature, decrease of NDVI and little variation in the surface albedo, between the two dates. These results also show an increase in the degradation of the natural resources in the basin of the Brígida river.
