针对开发建设项目水土流失预测方法现状,在充分考虑建设项目扰动堆积体物质特殊性的前提下,引入了土壤可侵蚀面的概念,并对开发建设项目的可侵蚀面进行分类。在此基础上,应用组合数学原理,利用侵蚀产沙函数和可侵蚀面的模块组合,建立基于可侵蚀面类型的开发建设项目水土流失预测模型。该模型的最大特点就是精度高、计算方便,所用参数容易获得,所得结果符合客观实际。
In view of the status quo of soil and water loss prediction methods for development and construction projects, the concept of soil erodable surface is introduced and the erodable surfaces of development and construction projects are classified on the premise of perturbing the material peculiarities of construction materials. Based on this, a combination of mathematical principles and the combination of erosion and sediment yield functions and erodible surfaces were used to establish a predictive model of soil erosion based on the types of eroded surfaces. The most important feature of this model is high precision, easy calculation, easy to get the parameters used, and the results are in line with the objective reality.
