چکیده

Undertaken activities in agricultural, industrial and urban productions emit gases that increase the greenhouse effect change both air temperature precipitation. These changes damage environment agricultural production alike, as well life on Earth. In light of this, present study has its objective to understand climate regime Lages/SC, a municipality located southern Brazil, analyze effects temperature, precipitation, consecutive dry days soil water balance. To end, historical series corresponding from 1948 2020 were used for maximum, average minimum temperatures, while 1961 order have balance calculated, precipitation considered input data method Thornthwaite Mather (1955). As potential evapotranspiration, storage available capacity, they calculated considering Humic Dystrudept, classified according Soil Taxonomy. Temporal analyses regarding days, intense rains conducted by using Mann-Kendall trend test (0.05). A positive increasing was observed over years. Although rainfall volume increased time, periods with fifteen been increasingly frequent. Despite distribution, there no occurrence or balance.Keywords: storage, effect, Cambisols. Mudanças climáticas e seu efeito balanço hídrico do solo de Lages, Santa Catarina.As atividades desenvolvidas nas produções agrícolas, industriais urbanas emitem que aumentam o estufa alteram tanto temperatura ar quanto precipitação. Essas mudanças prejudicam meio ambiente produção agrícola, bem como vida na Terra. Diante disso, presente estudo tem objetivo compreender climático em município localizado sul Brasil, analisar os efeitos das ar, precipitação, dias secos consecutivos solo. Para tanto, foram utilizadas séries históricas correspondentes para temperaturas máximas, médias mínimas enquanto cálculo hídrico, precipitação consideradas dados entrada método Quanto à evapotranspiração potencial, armazenamento água capacidade hídrica disponível, calculados considerando um Distrudado Húmico, classificado acordo com Taxonomia Solo. análises temporais referentes evapotranspiração, consecutivos, chuvas intensas realizadas por teste tendência (0,05). Foi observada uma positiva crescente ao longo dos anos. Embora tenha aumentado tempo, períodos quinze têm sido cada vez mais frequentes. Apesar temperatura, distribuição chuvas, não observadas alterações ocorrência ou solo.Palavras-chave: Disstrução Húmica, água, estufa, Cambissolos.

Soil water balance and ecosystem response to climate change.

Some essential features of the terrestrial hydrologic cycle and ecosystem response are singled out by confronting empirical observations of the soil water balance of different ecosystems with the results of a stochastic model of soil moisture dynamics. The simplified framework analytically describes how hydroclimatic variability (especially the frequency and amount of rainfall events) concurs w...
