| Abstract: | Relationships between structure factors and protection benefit of agroforests were studied through investigation in the field and analysis by multivariate statistical analysis. It was clear that the 3 indexes of mean diameter at breast height, coverage and distribution of trees could describe better the relationships between agroforestry structure features and its protection benefit. |
