Chase-and-escape motion, which is a typical behavior between a predator and prey, is an important dynamics in animate systems. It has been concerned recently in optics aiming for achieving novel light steering and switching functions. However, this optical counterpart can be realized in only one dimension because of the challenges in maintaining the chase-and-escape interaction.

易地搬迁是党中央做出的重大战略部署,是从根本上解决生态脆弱地区、偏远山区和民族地区群众脱贫发展的重要举措。易地搬迁社区的体育文化生态系统建构,不仅是社区文化建设的重要组成部分,更是促进搬迁居民社会融入、提升生活质量的关键途径。从价值逻辑看,它是实现国家搬迁工程的稳定的时代呼求,是促进易地搬迁居民社会适应的现实诉求,是培育居民文化认同与塑造居民价值秩序的理论诉求。从内容逻辑看,它是由体育社会生态和体育自然生态组成。从方法逻辑看,就搬迁居民而言,强化其文化认同;就政府而言,政府支持和认可其制度;就社会而言,关注和监督其发展是其基本实现路径。
