摘要
The natural vegetation in the State of Rio Grande do Sul was related to climatic availability through the climatic diagram of Walter and Lieth (1967). Values of mean monthly air temperature and rainfall from 41 meteorological stations during the period 1931-1960 were taken into account. For each meteorological station, a graph was plotted with months in the x axis and monthly air temperature and rainfall in the two y axis considering the y axis with rainfall two fold the y axis with air temperature. Results showed that Rio Grande do Sul as a whole fits in the zonobioma of warm humid temperate climate and forest vegetation. These results indicate the phytoclimate model of Walter and Lieth (1967) is not appropriate to represent the geographic distribution of the natural vegetation of the State, because this type of vegetation is not only that which covers the State that because it also parents praises.
