Modern control systems are featured by their hierarchical structure composed of cyber, physical and human layers. The intricate dependencies among multiple layers and units of modern control systems require an integrated framework to address cross-layer design issues related to security and resilience *** this end, game theory provides a bottom-up modeling paradigm to capture the strategic interactions among multiple components of the complex system and enables a holistic view to understand and design cyber-physical-human control systems. In this review, we first provide a multi-layer perspective toward increasingly complex and integrated control systems and then introduce several variants of dynamic games for modeling different layers of control systems. We present game-theoretic methods for understanding the fundamental tradeoffs of robustness, security and resilience and developing a cross-layer approach to enhance the system performance in various adversarial environments. This review also includes three quintessential research problems that represent three research directions where dynamic game approaches can bridge between multiple research areas and make significant contributions to the design of modern control systems. The paper is concluded with a discussion on emerging areas of research that crosscut dynamic games and control systems.

外来生物入侵是一个影响深远的全球性问题,对各国的生态系统、环境、健康、社会、经济发展具有重大的影响。尤其是近年来,随着全球气候变暖和全球贸易自由化的加快,外来入侵生物的种类和数量呈现快速增长趋势,生物入侵的威胁日益加重,若无行之有效的防控措施,外来生物入侵可能会形成"生物恐怖"。本研究以2019年1月联合国粮农组织全球预警的重大害虫--草地贪夜蛾第一次大范围入侵中国为例,分析了入侵生物对中国经济、生态与社会的影响,阐述了外来生物可能的入侵途径,剖析了当今时代背景下中国外来生物入侵防控面临的挑战,并针对入侵生物的入侵特点和影响,提出了完善"统一监管、分工负责"的管理机制、加快外来入侵物种立法、管理体系健全、执法监督体系建立、加强外来入侵物种的基础研究和防控网络建设、深入推进科普宣传与教育等综合防控对策。

酸性磷酸酶动力学特征可反映不同底物供应下土壤磷转化状况。以人工恢复的引进种黑松人工林和本地种栓皮栎人工林以及自然恢复的天然次生林为研究对象,开展凋落物添加去除和根系去除对土壤酸性磷酸酶动力学特征的影响研究。结果表明:(1)三种森林恢复方式下土壤酸性磷酸酶活性和最大反应速度(V_(max))均为双倍凋落物>对照>去除凋落物>去除根系>无输入;(2)改变凋落物和根系输入对酸性磷酸酶的半饱和常数(K_(m))和催化效率(V_(max)/K_(m))影响不大;(3)酸性磷酸酶活性受速效磷含量的反馈调节;土壤氮可利用性和含水量显著影响酸性磷酸酶活性。改变凋落物和根系输入对引进种黑松人工林土壤有机磷转化能力影响最大,天然次生林次之,本地种栓皮栎人工林最稳定。根系对土壤酸性磷酸酶动力学特征的影响大于凋落物。其结果可为暖温带森林恢复,应对气候变化和森林防火、收集凋落物等管理措施提供理论依据。
