Abstract:Paulownia elongata is a native plant of the Huanghuaihai Plain. In the present paper, P. elongata is mainly studied of the ecological habitats of the plant with the methods of dendroclimatology, dendrochrology, forestry and autoecology. It was found that the volume index is better than the yearly ring index in reflecting the relationship between the growth of P. elongata and the ecological factors. The results based on analysing the annual mass of P. elongata regarding climatic ecological factors by the mono-correlative, poly-correlative and stepwise multiple linear regression analyses show that the percentage of sunny time, hours of sunny time, ≥IO℃ accumulative temperature and rain-fall are the most important among the climatic factors affecting the growth of P. elongata. According to the analysis of soil factors and physical characters, we believe that the texture, depth and nutrients of the soil are more important than other soil factors affecting the growth of P. elongata. Furthermore, we have extensively discussed the fast-growth conditions of P. elongata and divided its growth area into different regions. Finally, we are convinced that P. elongata has a great potentiality for development and that intercropping with P. elongata is a real community type for intercropping in the central region of the Plain.
