VEGETATION MODEL OF ROBINIA PSEUDOACACIA L.IN THE LOESS PLANTEAU

Vegetation measure is the primary and effective way to control water and soil loss in the Loess Plateau.Robinia pseudoacacia L.is used mainly for preventing soil erosion in this area.The dynamic of Robinia will determine the function and results of controlling measures and balance of soil water.Models simulating Robinia growth is more regressional and less mechanistic.They are mostly used for predicting timber volume,and somewhat for predicting growth of the species from various environmental variables.Regression models about Robinia in the Loess Plateau are rigor but strict in local area.These models are generally preliminary;further in-depth studies are needed.Summarization of the growth model of Robinia was made to find out advantages,disadvantages,development and direction of the growth model for Robinia.
