Using the analysis of the distribution indexes method, the results indicated that all distribution indexes of Halostachys caspica population, Haloxylon ammodendron population and Haloxylon persicum population accorded with congregated pattern within the scales of 1m×1m、2m×2m、4m×4m、8m×8m、16m×16m、32m×32m. And the T-test evidenced that the deviation from random pattern was obvious in 1~32m scale.

Finally, we apply the factor analysis of the interest rate risk factors that change the yield curve of bond. Based on the comparison of the static models and stochastic models, we bring forward a dynamic stochastic risk management model of interest rate. In addition to this, we conduct an empirical examination of the management of risk immunized bond portfolios.
