| Abstract: | In the report, principal component analysis and cluster analysis were performed to analyze the de- struction factors of Brazilian Rain Forest, and the evaluation functions constructed were used to evaluate and sort the deforestation degree of nine regions in Brazil. The results suggested that the cattle industry and sugar cane planting have very significant destruct effects on Brazilian Rain Forest. Some suggestions on how to control defor- estation were also proposed. |
