“…Análises qualitativas e quantitativas do processo de fragmentação da vegetação nativa em matriz urbana têm sido pouco estudadas, apesar de fundamentais para que se tenham argumentos e direcionamentos nas tomadas de decisão pelos gestores das paisagens urbanas (SCOLOZZI;GENELETTI, 2012). A análise da paisagem utilizando técnicas de Sistema de Informações Geográficas (SIG) e métricas da paisagem auxilia na espacialização das informações sobre mudanças do uso do solo e tipo de cobertura, possibilitando a criação de cenários atuais e perspectivas futuras robustas do ambiente (GRIMM et al, 2000(GRIMM et al, , 2008YORK et al, 2011).…”

As métricas da paisagem são reconhecidas atualmente como bons indicadores de biodiversidade e são usadas em diferentes etapas do planejamento em conservação (LINDENMAYER et al, 2008;BANKS-LEITE et al, 2011;SCHINDLER et al, 2012).…”

Este estudo objetivou analisar a importância das Áreas de Preservação Permanente (APP) para a manutenção dos remanescentes florestais no município de Sorocaba, SP. O mapa desses remanescentes foi elaborado com base em fotografias aéreas de 2006, e mapas de hidrografia e de declividade foram usados para determinação das APP. Compararam-se dois cenários: real (mata atual) e ideal (mata atual acrescida da restauração das APP), com base em métricas da paisagem. Os resultados indicaram que 19% do município se enquadra como APP e, dessa área, apenas 45% possui cobertura florestal. As APP preservadas representam 50% do total de cobertura florestal da paisagem. A restauração das APP representaria aumento de 16,68% para 28% de cobertura florestal da paisagem e possibilitaria o surgimento de fragmentos maiores que 3.000 ha, enquanto no cenário real os maiores fragmentos atingem 300 ha. Os remanescentes florestais se apresentaram intimamente ligados às APP: margens de rios, áreas alagáveis e encostas, onde a ocupação urbana foi dificultada e existe o instrumento legal de proteção. Esse quadro evidencia que as APP possuem papel fundamental na conservação florestal em um município bastante urbanizado, onde as áreas naturais sofrem muita pressão. A avaliação dos cenários mostrou que a incorporação dos dispositivos legais no planejamento e ordenamento territorial subsidia as estratégias voltadas para a manutenção de hábitats naturais e, consequentemente, a diminuição dos efeitos negativos sobre a biodiversidade. Entretanto, as mudanças recentes no Código Florestal podem representar um retrocesso no cenário ambiental nacional diante da crescente urbanização.

“…Riitters et al (1995) carried out a factor analysis on landscape pattern indices to reduce the metrics dimension, but not to analyze urban heat islands. In some cases, all of the metrics have been used (Schindler et al, 2013). Uuemaa et al (2013) reviewed the trend of using landscape metrics as indicators for ecological processes and found that climate/microclimate regulation had received limited attention.…”

a b s t r a c tUrban heat island (UHI) is a global issue as a result of urbanization. Land surface temperature (LST) is closely related to the thermal environment and energy budget of the earth surface, and is an important parameter in identifying UHI effects. Previous studies have proved the effects of landscape pattern on LST by using landscape metrics. However, the metrics used were inconsistent in number and type. Further, fewer studies tried to select representative metrics from the numerous metrics for LST indication. In this study we tried to explore the effects of landscape pattern on LST in Beijing by using the representative class level metrics selected through cluster analysis, factor analysis and regression. The results showed a composition metric such as PLAND (e.g. percentage of impervious surface in a landscape) alone explained about 56% of the landscape mean LST, whereas adding a configuration metric such as LSI (landscape shape index) or Gyrate MN (mean gyration index) explained approximate another 6-12%. Adding more other configuration metrics does not improve the regression model performance more than 1%. The regression results also revealed that without targeted dependent variables, the factor analysis is of no use for choosing landscape metrics. These indicate that landscape composition and configuration both have effects on landscape mean LST, while composition is much more important than configuration, and that a combination of one composition metric with no more than four configuration metrics of impervious surface is sufficient for LST prediction. These results can help landscape ecologists in using landscape metrics and further help landscape planners to balance land cover in urban planning.

“…These metrics are not only used in UHI-landscape pattern analysis, but also in many other fields such as water quality and biodiversity (Schindler et al, 2013;Uuemaa et al, 2013). Nonetheless, these metrics face serious problems with redundancy and difficulty in interpretation (Cushman et al, 2008;Kupfer, 2012;Uuemaa et al, 2013).…”

a b s t r a c tStudies on the interactions between urban landscape patterns and land surface temperatures are the key to urban heat island (UHI) mitigation. However, the landscape pattern indices used in previous studies were inconsistent in type and number. Furthermore, few studies combined the composition and configuration indices into one integrated indicator. The description of landscape pattern is thus a great yet rewarding challenge. In this study, we used the integrated location weighted landscape index (LWLI) proposed by Chen et al. (2009) and revised it to indicate potential UHIs. Fifty-six circular landscape samples along four transects were created and the LWLI was derived based on the theory of the GINI index. The LWLI considers the type, composition and configuration of different land covers inside a landscape, where configuration is treated as location weights. The potential UHI was represented by the land surface temperature (LST) of each circle landscape center. The correlation analysis results showed that the LWLI was significantly positively correlated with summer potential UHIs, with a Pearson R equaling 0.736, and barely correlated with winter potential UHI. Moreover, the LWLI was slightly more strongly correlated with potential UHI than composition alone. These correlations weakened as the landscapes grew larger. The linear regression results further revealed that the LWLI explained about 53% of the summer potential UHI, which was slightly better than composition alone (49%). This indicated that the LWLI was as effective in predicting the potential UHI as the combination of several pattern indicators, echoing Tobler's first law of geography, which states that "all things are related, but nearby things are more related than distant things." This study also leaves room for improvement of the index by integrating more environmental/ecological parameters as weights, and for further application of the index in other fields.
