| 摘 要： | 以B市密云水库流域为例,用计算机数值模拟技术模拟坡面降雨侵蚀过程,考虑到坡面流的流速及非线性双曲型方程,采用迎风有限差分显示格式来离散坡面侵蚀方程、坡面水流连续方程、水流运动方程,并编制了计算程序,进行了计算机模拟.研究成果可以描述动态坡面降雨侵蚀及水土流失过程,且可将研究成果扩展到整个流域,从而为治理水土流失保护生态环境提供依据.

| Abstract: | Computer digital simulation technology is a very important domain of computer application, in this article we use it to simulate Beijing Miyun reservoir river basin.The mathematic model includes slope erosion equation, slope water continuous equation and water kinematical equation. Considering the velocity of the water streams and the nonlinear equation, we used facing wind finite difference method solve the equation, and made the program. The calculation result indicates that we got satisfied simulation. Our research can describe the slope erosion situation trends, and expand to whole river basin, so it can provide important basis for administering water and soil erosion. |
