- Abstract:
-
In order to study the soil improvement effects of different afforestation species, soil samples were collected from afforested woodlots different in tree species for lab analysis of fertility and alkalization characteristics, of which a systematic study was done with the mothed of subordinate function and principal component analysis. Results showed that afforestation could improve soil structure, reduce soil bulk density, improve soil fertility, reduce the degree of soil salinization, which transformed the medium salinization to light salinization, desalination process and alkalization process coexisted; soil fertility in different afforestation models decreased in the order: Black locust > Winter jujube > Poplar > Mulberry > Chinese ash > Elm > Amorpha > Tamarisk; soil alkalization levels decreased in the order: Amorpha > Tamarisk > Elm > Poplar > Chinese ash > Black locust > Winter jujube > Mulberry.
