Abstract

The government of São Paulo State, Brazil, forty years ago, carried out a program of introduction of forest species with the main objective to consolidate the Pinus culture in the State. Some of these forests were implanted in areas of the Cerrado that were degraded due their use for grassland. The aim of the present work was to verify the hydrometeorologycal characteristics of Pinus elliottii forest, located in Cerrado, in the central region of São Paulo State, and to compare some characteristics among forest, grassland and lawn. In the forest were installed two automatic meteorological stations, one on the tower top and other inside of the forest. The partitionings of the precipitation by manual measurement were 75.2% for throughfall, 0.5% for stemflow and 24.3% for forest interception. By automatic measurement it was obtained 78.7% for throughfall. Forest\'s albedo presented an average value of 12.8% and net radiation ranged from 6.0 MJm-2day-1 to 14.2 MJm-2day-1. The diference of average air temperature between the canopy and the interior of the forest was 0.4ºC. This study presents a great contribuition to the national ambit of the hydrometeorologycal monitoring in forests. (AU)
