O objetivo do presente trabalho foi avaliar e caracterizar a variação sazonal da Temperatura do Solo (TS) em relação ao Saldo de Radiação (Rn) em uma Floresta de Mata Atlântica no município de Coruripe – Alagoas, e ainda contribuir com o sistema conservacionista deste bioma. Diversos autores têm demonstrado que a distribuição de espécies arbóreas de Mata Atlântica está diretamente relacionada com variáveis climáticas como precipitação pluvial e temperatura do ar, especialmente a TS, além do Rn. Então, o entendimento e avaliação dos impactos climáticos que a Mata Atlântica de Alagoas vem sofrendo com o desmatamento desordenado passou por estudos observacionais que procuraram descrever as inter-relações biosfera-atmosfera, dentre eles a avaliação e a caracterização da TS. Com a metodologia proposta foi verificada as variações da TS em seu interior nos níveis de 0,01; 0,05; 0,10; 0,15; 0,20; 0,25; 0,50 e 1,00 m de profundidade, sendo mais elevadas nos períodos seco com maiores índices de Rn e mais baixas no período chuvoso com menores índices de Rn.

Evaluation and Characterization of the Temperature of the Soil In Relation to Precipitation and to the Balance of Radiation Inside of a Forest of Atlantic Forest In Coruripe – Alagoas
ABSTRACT
Temperature of the Soil (TS) in relation to the Balance of Radiation (Rn) in a Forest of Atlantic forest in the municipal district of Coruripe. Alagoas, and still to contribute with the conservationist system of this bioma. Several authors have been demonstrating that the distribution of arboreal species of Atlantic forest is directly related with climatic variables as pluvial precipitation and temperature of the air, especially TS, besides Rn. Then, the understanding and evaluation of the climatic impacts that the Atlantic forest of Alagoas is suffering with the disordered deforestation passed for studies observacionais that tried to describe the interrelations biosphere-atmosphere, among them the evaluation and the characterization of TS. With the proposed methodology it was verified the variations of TS in his/her interior in the levels of 0,01; 0,05; 0,10; 0,15; 0,20; 0,25; 0,50 and 1,00 m of depth, being higher in the periods dries with larger indexes of Rn and lower in the rainy period with index minor of Rn.
