Abstract:
The content of soil carbon(C)，nitrogen(N)，phosphorus(P) of Abies fanjingshanensis and Davidia involucrata and the relationship between soil and Abies fanjingshanensis and Davidia involucrata in Fanjing Mountain was studied,and compared the contents in Fanjing Mountain with that in other areas，to explore situation and major limiting factor of soil nutrient，to promote the coordinate development between the rare plant and tourism development.The results showed that the soil nutrient content of Abies fanjingshanensis was higher than that of Davidia involucrata.The average content of soil organic carbon(SOC) of Abies fanjingshanensis was considerably larger than that of Davidia involucrata. The content of soil alkali-hydrolyzable N of Davidia involucrata was 672.14 mg/kg，it was higher than that of Abies fanjingshanensis，which was 164.02 mg/kg.The average content of total N (STN)，P (STP) and available P of Abies fanjingshanensis were 2.24 g/kg，1.14 g/kg，13.13 mg/kg，respectively，and that of Davidia involucrata were 14.59 g/kg, 0.09 g/kg,27.39 mg/kg，respectively.The soil nutrient could provide the favorable growing conditions for the two rare plants.The content of soil C,N,P of Abies fanjingshanensis was higher than that of Abies georgei，Abies beshanzuensis，Abies nephrolepis and Abies faxoniana.The available P was obstacle fator，even limited fator of polulation growing for Abies fanjingshanensis.The content of soil C,N,P for Davidia involucrata was on morderate level，and the limited fator of polulation growing for Davidia involucrata was SOC.The STN was significantly correlated with the SOC for the two rare plants in Fanjing mountain，but the STP was significantly negatively correlated with the SOC.The STN and SOC had the significant same source，but the STN and STP had the opposite source.
