Resumo(s)
The field research was carry on in the Southwest of Angola, in a transect between
Tundavala (Lubango ) and Tombua, in the provinces of Huila and Namibe.
It was done a bioclimatic study of Angola, according the Wordwide Bioclimatic
Classification System of Rivas-Martínez, which achieve to seven bioclimatic maps:
positive annual temperature, positive annual precipitation, bioclimates, continentally
index, thermicity index, thermotypes and ombrotypes. In our study area, the bioclimatic
ranges from the tropical hyperdesertic thermotropical upper hypearid and tropical
pluviestacional lower mesotropical lower sub-humid.
Regarding the flora we identified 510 taxa, (including 74 endemic from Angola) and
distributed for 84 families.
Based on the 256 phytosociological reevés carried on, we identified 41 syntaxa to
Southwest Angola, spread over 4 classes, 5 orders, 8 alliances, 20 associations and 4
communities. All these are original syntaxes with exception of 1 class, 2 orders and 1
alliance. Finely, it was possible to defined 13 vegetation series and 9 permasigmeta.
Taking account the UPGMA classification with the Bray - Curtis distance, was possible
to obtain thirty one groups that corresponded, in general, to our proposal of associations
with the exception of three
