| 英文摘要 | A recent review of the structure of arid zone ecosystems supports the idea that vegetation is commonly made up of two spatial patterns called Tiger bush and Leopard bush. It is suggested that the distribution and composition of the Leopard pattern is caused by the interaction between anthropic and biophysical aspects. The present research aims to investigate the Leopard pattern in the La Guajira peninsula, a biophysical approach was implemented that integrates GIS and Remote Sensing technologies. Information collected in the field, satellite images, and digital elevation models were used to produce plant distribution maps. The analysis of the soil nutrients showed how the values of N, P, K vary in bare soils and in the fertility islands formed by the vegetation where the cacti are part of the pattern, being reported for the first time. The Leopard pattern is the result of specific characteristics that limit plant life forms, by limiting development to only certain resistant species, these make up communities and in turn generate strategies to optimize available resources. In the Leopard pattern of La Guajira, compacted soils and spaces fragmented by anthropic influence were shown to be one of the main factors in the resulting heterogeneity. |
