摘　　要：聚氨酯塑胶跑道由基础层和胶面层组成,具有较好的弹性,可以有效减少运动者体力消耗,保护膝关节和脚部,减少运动员的受伤风险。高校常见的聚氨酯塑胶跑道包括全塑型、复合型、混合型和颗粒型,分析这些跑道的特点和发展现状,并对聚氨酯塑胶跑道未来发展趋势做出简要论述。A polyurethane plastic track,composed of base layers and rubber surface layers with a good elasticity,can not only effectively reduce the physical consumption of athletes but protect the knee joint and feet so as to reduce the injury risk of athletes.Common polyurethane plastic runways in colleges and universities include full plastic,composite,mixed and granular types.The characteristics and development status of these runways are analyzed,and the future development trend of polyurethane plastic runways is briefly discussed.
