摘 要:针对淤地坝坝系建设中存在的建坝时序问题,提出了淤地坝建坝时序的数学模型。该模型考虑的主要因素有:拦泥效益以及坝地的生产效益。按照效益最大化的结果求出最佳的建坝顺序。与其它模型比较,该模型的主要特点是考虑了三点实用的因素,即贴现率,保收率和建筑费。最后以虎山沟为例,使用该模型得到了建坝时序和效益,模型的合理性是通过计算的效益最大来证明的。This article put forward a sequential mathematical model for warping dam construction in small watershed. The productive benefit and sediment holding capacity of the dam were considered as the main elements. The best construction sequence was based on the analysis of maximizing economic benefit. Comparing with other models, the model took three practical factors of discount rate, harvest insuring rate and constructive investment into account. Finally, the model was applied to Hushan small watershed to prove its rationality.
