Résumé
The present thesis is framed within the General Theory of Systems, area of knowledge denominated Systemic Ecology and for this reason is structured going through the general (Theory of the Ecosystem) to the particular (Terrestrial Mediterranean Ecosystem). For the same reason, it goes through - in the semiotic interpretation of the Reality or Model - the general (mathematical model) to the particular (mathematical model ARGILAGA of a mediterranean shrub species, following the SDWTF methodology). The objective is to develop a mathematical model analyzing and evaluating changes suffering the mediterranean vegetation, and the consequences that can have on the hydrological cycle, soil protection in front of the erosion and vegetable landscape evaluation. It has been necessary to connect the development of the model in species that are, at the same time, representatives of a terrestrial mediterranean ecosystem playing an important paper in the genesis of fires and ecological post-fire evolution. The model is summed up studying the biomass dynamic behavior of the main pirophyte shrub species Ulex parviflorus, and its relationship with other shrub species, starting from its ecological conditions of post-fire stage and its grade of effectiveness like covered protector in front of the erosive processes, to short, half and long term, so much under normal conditions as limits (desertification). ARGILAGA model has as main goal to observe this behavior being able to foresee and intervene consequently with appropriate measures of protection, restoration and administration. Also, to justify the survival of the species for their importance in soil retention and erosion elimination, to originate banks of seeds, etc. To avoid their possible extermination with the techniques of forest repopulation used in the current moment and knowing in that stage of their biological cycle can begin and establish this control. If mathematically modeling can know biological strategies, we will be able to impact orderly in the complexity of the terrestrial mediterranean ecosystem
