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。
As far away from the original living environment or natural enemies, making some plants grow too fast, affecting the local environment, known as plant invasion. With the development of tourism and economy and trade, the harm caused by invasive plants will become more and more serious. Therefore, it is necessary to study qualitatively and quantitatively a method to effectively control plant invasion. In this paper, different models of early and late stage were established for the control of harmful plant invasions. The huge computational problems were solved by computer programming, and the optimal solution of the model was obtained. The optimal solution was used to understand its practical significance. Through numerical simulation and discussion, the actual application value of quantitative research on invasive plant control is illustrated.
