The model includes that the relationship between median diameter, as well kinetic energy, of raindrop and rainfall intensity obeys logarithmic function, the critical slope degree of soil erosion is 38.4°~43.0° in test area and the best multiple index of rainfall erosivity value is /100. Employing the prediction model, the soil erodibility value, the accelerated value of excavation slope, roadbed slope, construction site, borrow pit, service road and other temporary occupation land and the loss-spoil ration of waste pile were examined. Finally, the integrated soil and water conservation measures in highway construction project have been suggested.

Value at Risk was main tool of market risk management but traditional VaR did not appreciate liquidity risk to make that VaR did not give correct information and was disvalue VaR to lead a large number of damages.
在现如今的风险管理工具中,风险值是应用最为广泛的一种,但在以往传统的风险值度量模型中,并不重视或是基本不考虑流动性不足问题所带来的风险,这使得风险值无法提供给投资者完全、真实、可靠的信息,更严重的问题是错估风险值会造成更大的损失。
