With debris population keeping growing, near-earth space environment becomes more deteriorating. Current debris mitigation measures are not enough to limit the growth of debris population, and active debris removal measures must be taken. By predicting the growth trend of space debris, it is urgent to mitigate debris in low earth orbit(LEO). The mitigation strategy is analyzed in the view of choosing targets and mitigation techniques. The work may make sense in the mitigation work in the future.%随着碎片数量的不断增长,近地空间环境日益恶化.现有碎片减缓措施不能有效限制碎片数量的继续增长,必须采取主动清除措施.通过对空间碎片增长趋势的预测,指出了近地轨道(low earth orbit,LEO)空间碎片清除的迫切性,从目标选择和清除技术2个方面分析了碎片的清除策略,对未来空间碎片的清除工作具有一定的指导意义.
