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 threeporbioclimatologyphytosociologyfloravegetationlandscapeAngoladoctoral thesis101265417
