Resumen
Se analiza la relación entre la dinámica territorial en el uso de la tierra con respecto a los cambios en el régimen hidrológico en la región central de Costa Rica. Se hace una comparación entre dos años y se encontró que tal proceso ha sido muy intenso de un año al otro. La fuerte presión urbanística e industrial sobre los suelos más fértiles del país, ha provocado modificaciones en el régimen hidrológico de las dos principales subcuencas hidrográficas: Virilla y Grande de SanRamón, ambas conforman la cuenca del río Grande de Tárcoles. La subcuenca del río Virilla no logra almacenar el agua pluvial, especialmente si se considera que un alto porcentaje de su área está cubierta por usos de tierra de tipo urbano. Por el contrario, la subcuenca del río Grande de San Ramón logra retener un mayor porcentaje de aguas, al tener usos de la tierra dominados por pastos, cultivos y bosque. En síntesis, varios de los usos de la tierra incrementan su área, en especial el área urbana, con la gran excepción del área de bosques que se redujo considerablemente.
It analyzes the relationship between territorial dynamics in land use and changes in the hydrological regime in the Central region of Costa Rica. A comparison is made between two years and the results showed that this process has been intense from one year to another. The urban and industrial heavy pressure on the most fertile soils of the country, has led to changes inthe hydrological regime of the two major sub-basins: Virilla and Grande de San Ramón, both of which constitute the Basin of Grande de Tarcoles River. The sub-basin of the Virilla Rivercan not store rainfall, especially considering that a large percentage of its area is covered byland uses of urban type. In contrast, the sub-basin of the Grande de San Ramón River retains a higher percentage of water, having land uses dominated by pasture, crops, and forests. In synthesis, several land uses increase their area, especially urban areas, with the major exception of the forest area which was reduced considerably.
