摘要 Plant invasion refers to the phenomenon that some plants grow too fast due to they are far away from the original living environment or predators, affecting the local environment. With the development of tourism and trade, the harm caused by invasive plants will be more and more serious. Therefore, it is necessary to ex- plore an effective method for controlling plant invasion through qualitative and quan- titative research. In this paper, the models were established for the early and late harmful plant invasion control. The huge computation was completed by the com- puter programming to obtain the optimal solutions of the models. The real meaning of the optimal solution was further discussed. Through numerical simulations and discussion, it could be concluded that the quantitative research on the invasive plant control had a certain application value. 由于远离原本的生活环境或天敌,使得一些植物生长速度过快,影响了当地环境,称为植物入侵。随着旅游和经贸的发展,入侵植物造成的危害将越来越严重,因此有必要定性定量地研究一种有效控制植物入侵的方法。该文对于有害植物入侵控制建立了早期和晚期的不同模型,通过计算机编程解决巨大的计算问题,得到模型的最优解,并通过最优解了解其实际意义。通过数值模拟以及讨论,说明入侵植物控制的量化研究实际的应用价值。
