摘要
当河流兼具发电、供水、防洪和生态保护等多种功能时,航道承载力如何兼顾多目标协同发展及量化问题成为当前航道建设研究的重要问题。运用改良变异法,并结合航道承载力对生态、经济、河流多功能利用等目标的承载水平评价值,对航道承载力进行协同互适的调控,计算出多目标协同下的最大航道尺度,并通过AE航道作为算例对评价模型与计算方法的合理性及可操作性进行验证。结果表明,计算出的最大航道尺度可缓解当前航道建设与经济、生态和河流多功能利用发展中的矛盾;计算模型合理、可行。
The rivers have many other functions,such as generating power,supplying water,preventing flood and protecting ecological areas,and how to balance multiple goals and achieve synergistic development and quantification of channel carrying capacity in channel construction has become one of the most important problems today.By using the modified variance coefficient,we carry out coordinated and adaptive regulation of channel carrying capacity combining with the horizontal evaluation value of channel carrying capacity on ecological,economic and multi-function utilization of river,calculate the maximum channel size under multi-objective coordination,take AE channel as an example to verify the rationality and operability of the evaluation model and calculation method.The results show that the maximum channel size calculated can alleviate the contradiction between current channel construction and economy,ecology and rivers,and multi-purpose utilization.The calculation model is reasonable and feasible.
