基于系统周界的观控模型及其可观控性定理,把淤地坝坝控流域概化为一个系统进行研究,通过对其输入、输出与内部状态及其之间的关系进行分析,得出了系统周界的观控模型可以对某一输入使其按评价水平的要求进行观控的结论.通过对陕西省榆林市子洲县南部的小河沟流域的石畔峁坝坝控流域进行观控分析,发现该模型在有效的评价水平的指引下,能够对输入该流域的人类活动影响做出分析、判断与调控,从而达到减小流域侵蚀的目的,实现了流域系统的协调稳定发展,开阔了淤地坝研究的思路.
Based on the observation and control model of the system perimeter and its observability control theorem, the dam-controlled dam of siltation dam is generalized as a system. By analyzing its input, output and internal states and their relations, The observation and control model of the system perimeter can make a conclusion that an input should be controlled according to the evaluation level.According to the observation of the dam bank of the dam in Xiahegou watershed in the southern part of Zizhou County, Yulin City, Shaanxi Province It is found that this model, under the guidance of effective evaluation, can analyze, judge and control the impact of human activities input into the river basin so as to reduce the erosion of the river basin and realize the coordinated and steady development of the river basin system. Open up the study of silt dam.
