Abstract

Abstract:

The vertical distribution changes of Robinia pseudoacacia fine roots were investigated in Ansai County of Shaanxi Province (a semi-arid region) and Jingchuan County of Gansu Province (a sub-humid region) on the Loess Plateau by using root-auger method from June 2007 to April 2008. The collected data verified that the model of S=h^B(M+Nh+Uh²+Vh³) was able to well fit the fine root vertical distribution (where h= depth of soil, S= total surface area of the fine root in the h). By determining the value of parameter B and establishing functions of M, N, U, V on parameter t (month), a dynamic model was established for describing changes of the fine root growth with h and t. It was validated the model could be used to accurately calculate the total surface area of the fine root in different water ecological zones of the Loess Plateau, would have a high application value.

Key words: Robinia pseudoacacia, total surface area of fine root, model of growth, the Loess Plateau
