Abstract: The Soil ecological stoichiometry properties in different re-vegetation stages(including preliminary stage(Ⅰ), middle preliminary stage(Ⅱ), middle anaphase(Ⅲ) and anaphase(Ⅳ)) and soil layers(including soil layers of 0～10 cm, 10～20 cm, 20～40 cm, 40～60 cm, 60～80 cm, 80～100 cm and 0～100 cm ) in Hengyang City of Hunan Province, South-central China were studied by using the method of the space for time. The results showed that: (1)In the process of re-vegetation, SOC(Soil organic carbon) in each soil layer of every re-vegetation stage first increased then decreased and presenting a regulation “anti-U”, TN(Total nitrogen) and TP(Total phosphorus) were significantly decreased with the increase of soil depth and showing a clear table cohesion, the content of SOC showed the regulation of wave and showing significantly differences(P＜0.05), TN and TP were followed the order as anaphase(Ⅳ)＞middle anaphase(Ⅲ)＞middle preliminary stage(Ⅱ)＞preliminary stage(Ⅰ)(P＜0.05); (2)In the process of re-vegetation, the SOC, TN and TP content of 0～100 cm soil layer were significantly increased(P＜0.05), but the C/N, C/P and N/P were significantly decreased(P＜0.05); (3)Correlation analysis showed that there was extremely significantly positive correlation between C/N and SOC, SER(Soil electricity rate)(P＜0.01), and extremely significantly negative correlation with TN, TP, SWC(Soil water content), SBD(Soil bulk density); C/P was extremely significantly positive correlation with SOC(P＜0.01), and extremely significantly negative correlation with SWC and SBD; N/P was extremely significantly positive correlation with SOC, TN, TP, pH value(P＜0.05 or P＜0.01), and extremely significantly negative correlation with SBD and SER(P＜0.01). All the results indicated the demands of N and P content in soil by plants were consistent in the process of re-vegetation.
