我们建立了基于线性系统分析的海滩清理效果（BCE）评估方法，并研究了决定BCE的因素。在这里，我们重点关注两个 BCE：减少海洋塑料中可能渗入海滩的有毒金属的总质量，并防止海洋塑料在海滩上破碎。两个 BCE 都强烈依赖于海洋塑料在海滩上的平均停留时间 (tau(r)) 和海洋塑料输入通量的时间变化周期 (1)。 tau(r) 长于 Tare 的海滩上的清理工作比 tau(r) 短于 T 的海滩上的清理工作更有效。此外，两个 BCE 均在塑料残留达到局部最大值的时间（峰值时间）附近达到最高。因此，了解以下三个因素对于有效清理至关重要：平均停留时间、塑料输入周期和峰值时间。 (C) 2014 Elsevier Ltd. 保留所有权利。
We established a method for evaluating beach cleanup effects (BCEs) based on a linear system analysis, and investigated factors determining BCEs. Here we focus on two BCEs: decreasing the total mass of toxic metals that could leach into a beach from marine plastics and preventing the fragmentation of marine plastics on the beach. Both BCEs depend strongly on the average residence time of marine plastics on the beach (tau(r)) and the period of temporal variability of the input flux of marine plastics (1). Cleanups on the beach where tau(r) is longer than Tare more effective than those where tau(r) is shorter than T. In addition, both BCEs are the highest near the time when the remnants of plastics reach the local maximum (peak time). Therefore, it is crucial to understand the following three factors for effective cleanups: the average residence time, the plastic input period and the peak time. (C) 2014 Elsevier Ltd.
