2011赛季中国足球超级联赛各球队攻防能力的统计分析

通过文献资料、录像观察、数理统计以及RSR秩和比评价等研究方法，对2011赛季中国足球超级联赛各球队的攻防能力进行量化与探究，结果表明：中超足球各参赛队实力有较大差距，根据RSR值分析结果划分为5个等级，其中广州恒大队与对手相比具有很大优势，在进攻能力上，主要体现在进球数、射门次数、射门被封次数、控球率以及传威胁球次数等指标与对手差异均具有高度显著性（P〈0．Ot），射门成功率和传球成功率与对手差异具有显著性（P〈0．05）；在防守能力上，失球数、铲球成功率、解围次数等指标与对手球队差异具有高度显著性（P〈0．01），封堵射门次数、抢断成功率以及犯规次数等指标与对手差异具有显著性（P〈0．05）．而2支降级球队与对手也存在很大差距，在进攻能力上，主要体现在进球数指标与其他球队差异具有非常显著性（P〈0．01），射门次数、射门被封次数以及传威胁球次数等指标与对手差异具有显著性（P〈0．05）；在防守能力上，抢断成功次数和铲球成功率与对手差异具有高度显著性（P〈0．01），失球数指标与对手差异具有显著性（P〈0．05）．

Statistical Analysis of Attack and Defense Ability of Each Team in 2011 CSL

In the report,the methods of literature review,video watching,mathematical statistics and RSR were used to analyze the attack and defense ability of each team in 2011 CSL games.The results indicated that there are great differences among teams,according to the RSR data,there are five levels.The offensive capacity of Hengda is superior to its adversaries extremely significantly(P<0.01),including its goals,shooting times,dominated possession and so on.There are significant differences in shoot success ratio and passing success ratio(P<0.05).There are extremely significant differences in the defensive capacity between Hengda and its adversaries including goals against,tackles success ratio and rescue frequency(P<0.01).There are significant differences in the defensive capacity between Hengda and its adversaries including blocking shot time,plucking success ratio and fouls time(P<0.05).There are extremely significant differences between the offensive capacity of two demotion teams and that of others,including goals(P<0.01),and there are significant differences between the offensive capacity of two demotion teams and that of others,including shooting times and blocking shot time(P<0.05).There are extremely significant differences in the defensive capacity between Hengda and its adversaries including goals against,tackles success ratio and rescue frequency(P<0.01).There are extremely significant differences in the defensive capacity between Hengda and its adversaries including goals against(P<0.05).
