R E S U M OAs mudanças no uso e na ocupação do solo, provocadas pelas ações antrópicas, têm gerado grandes impactos nas paisagens. Esses impactos podem ser mitigados através do monitoramento do uso e da cobertura do solo utilizando-se informações espaço-temporais das modificações ocorridas na paisagem. Este trabalho apresenta uma análise espaço-temporal detalhada da dinâmica do uso e ocupação do solo da bacia hidrográfica do riacho São Paulo, localizada na região semiárida do Estado de Pernambuco, entre os anos de 1991 e 2010. Partindo da classificação de três imagens de satélite dos anos de 1991, 2000 e 2010, foram utilizadas matrizes de transição, associadas à álgebra de mapas e métricas da paisagem. Os resultados mostraram que durante o período estudado as classes de uso e ocupação do solo passaram por uma grande transição, com a substituição progressiva das áreas de vegetação de caatinga aberta por áreas com pastagem/agricultura. Junto com o rápido crescimento da classe pastagem/agricultura, a paisagem predominante de vegetação nativa foi sendo substituída por uma paisagem cada vez mais devastada, heterogênea e fragmentada, como mostraram os índices das métricas da paisagem.Dynamic of land use/cover change processes in a Brazilian semiarid watershed A B S T R A C TThe changes in the use and occupation of land, caused by human actions, have created major impacts on the landscapes. These impacts can be mitigated by monitoring the use and land cover, using spatial and temporal information of the changes occurring in the landscape. This paper presents a detailed analysis of spatial and temporal dynamics of land use and occupation of the stream São Paulo watershed, located in the semiarid region of Pernambuco State, during the period from 1991 to 2010. Based on the classification of three satellite images for the years 1991, 2000 and 2010, transition matrices were used associated with the algebra of maps, and landscape metrics. The results showed that during the studied period, the classes of land use and occupation went through a major transition, with the gradual replacement of sparse area of 'caatinga' vegetation by grazing areas/agriculture. Along with the rapid growth of the grazing areas/agriculture class, the predominant landscape of native vegetation has been replaced by a landscape increasingly devastated, fragmented and heterogeneous, as shown by the index of landscape metrics.

“…The driving forces of LUCC are diverse and scale-dependent, among which a wide variety of socio-economic and physical factors have been identified. Socio-economic factors include economic development (Liu et al, 2014a), population growth (Liu et al, 2005), policy regulation (Xie et al, 2005), urbanization , land use management (Yu et al, 2011), advances of science and technology (Hai et al, 2005), road construction (Liang et al, 2014), and enhancement of environmental awareness (Fan et al, 2012). Physical factors include climatic change (Gao et al, 2006;Song et al, 2009), geomorphological processes (Wang et al, 2005a), water availability (Zhang et al, 2006), and land-ocean interactions .…”

“…Modelling is a useful tool to give insights into the processes, mechanisms and environmental impacts of LUCC, and various types of LUCC models have been adopted, modified and developed by Chinese scholars for different purposes (Dai et al, 2005;Huang et al, 2005;Wu et al, 2007;Luo et al, 2010;Yu et al, 2011;Xu et al, 2015;Wu et al, 2015b). Most of these models can be grouped into three categories: empirical-statistical models, concept mechanism models, and integrated models.…”

Modern physical geography in China grew from Chinese traditional geography and has been profoundly influenced by the geographical disciplines of Euro-America and Russia. Since the 1950s, integrated studies of physical geography in China have made remarkable progress in the fields of comprehensive physical geographical regionalization, land studies, landscape ecology, and land surface geographical processes. During the past few decades, under the background of global change and rapid socio-economic transformation, a series of environmental and resources problems have boomed in China. To solve these problems and promote the development of integrated studies of physical geography, the following issues were proposed as research priorities: (1) coupling of land surface patterns and processes; (2) integrated research on regional responses and adaptation to global change; (3) analysis of human dimensions of the earth system; (4) ecosystem service research from a geographical perspective; (5) integration of multi-source data and model development; (6) integrated studies on unique geographical units; and (7) important global issues and relevant international programs.
