Pinus elliottii is one of the excellent tree species for soil and water conservation. In order to objectively reflect the soil and water conservation and economic benefits of Pinus elliottii, the growth process information of 7 Young Pinus elliottii trees in Lishuqiao small watershed was observed and counted year by year, and the verhalst prediction model for the growth process of tree height, ground girth diameter and crown diameter of Young Pinus elliottii trees was constructed and analyzed. The conclusions are as follows: 1. The growth process curve of Pinus elliottii for years is step-shaped and periodic. If we do not strengthen tending management and only take closure measures, it is likely to become "small old trees"; 2. Verhalst model is suitable for establishing the growth process model of Pinus elliottii with short data series. It has the features of low demand for data and high accuracy, and can be popularized in the red soil hilly areas of the south of the Yangtze River.
