| 摘 要： | 介绍并评价目前开发建设项目土壤侵蚀模数预测的几种方法。在侵蚀倍率法基础上，通过对土壤侵蚀因子分析，认为开发建设项目区扰动前后土壤侵蚀模数比值与地表相对裸露度、土体相对稳定性和土体相对密实度的乘积相关，根据少量监测或实测数据可初步确定不同侵蚀类型区的待定系数，推算出各防治区扰动后土壤侵蚀模数，从而提出了因子分析法的初步研究设想。

| Abstract: | This paper analyses the present prediction methods on soil erosion modulus for development and construction projects.It is found that soil erosion modulus in different development and construction projects are related to the relative area of bare earth surface,stability of soil,density of soil and so on.So the factor analytical method which introduced in this paper is decided by both the factors of soil erosion modulus and the data of field observation and dynamic monitoring.The further modification of pred... |
