Abstract: Afforestation is an important way to improve soil condition in coastal saline land.?In order to study the soil improvement effects of different plantations in coastal saline land of the Yellow River delta, we analyzed the soil physiochemical properties and their correlation of four different plantations and the control of the unplanted land. Also, the factor analysis was used to evaluate the soil improvement effects of four different plantations. The results showed that:1) The four different plantations could improve the soil physiochemical properties in coastal saline land of the Yellow River delta, reduce the soil bulk density and salinity, and increase the contents of organic matter and available nutrients. Moreover, there was a certain correlation between the physiochemical indicators.2) The result of factor analysis showed that soil improvement effects of different plantations was obtained in the following order: Fraxinuschinensis (1.223) > Pyrus betulifolia (0.686) > Tamarix chinensis (0.307) > Salix psammophila ‘YanliuYihao’ (-0.107) > CK (-2.108).
