【摘要】 本论文以伊犁马为对象，研究体尺与竞赛性能的关系，以确定伊犁马的选择指标，并探讨在不同条件下，选用合理的指标对伊犁马进行选择；根据参赛马的奖金数计算IIPA值，通过细分体尺与IIPA值把体型结构评定与竞赛性能评定相结合用于伊犁马的选择。数据来源：1、深圳赛马会96赛季伊犁马各赛程成绩、赛马的奖金数和基本体尺及年龄。2、采用瑞典的体尺细分法，测定了乌鲁木齐马术俱乐部24匹伊犁马19个细分体尺及1000米速度成绩。借助DPS统计软件分析基本体尺、细分体尺与速度的相关性，结果为：基本体尺中，体高、胸围、管围、年龄与速度呈显著或极显著相关；细分客观体尺性状中颈长、肩长、肱骨长、股骨长、胫骨长、肩倾角、股骨倾角、髋骨倾角与速度呈显著或极显著相关。采用因子分析，按85％的贡献率从细分客观体尺中提取出三个主因子，依次为牵引力因子、支持力因子、推动力因子，经因子分析剔除剩余信息后进行聚类分析，可将24匹伊犁马分为优、良、中、差四个类。相对细分体尺结果表明：伊犁马的速度不但和各个关节的绝对长度有关，而且和其比率有关，比率在一定范围内才利于速力的发挥。采用颈长率、肩长率、肱骨率、胫骨长率、股骨长率及体高建立最优回归方程（P<0.05），通过该方程可对成绩进行预测。深圳赛马会96赛季伊犁马IIPA值计算结果为：87匹马超过了群体均值100，占总数的44.162％，25匹马的IIPA值超过120，占总数的12.690％，4匹马IIPA值超过140，占总数的2.030％。因此，可根据不同的条件，选用不同的体尺指标或IIPA对伊犁马进行选择。用马者与育马者在选马、交易或拍卖马匹、选种选配、淘汰马匹、性能评定等都可以细分体尺指标或IIPA值作为衡量依据。其作为双方均认可的指标，将用马者与育马者结合在一起，两者相互促进，不断培育出竞赛性能优良的马。更多还原

【Abstract】 In this discourse we studied the relationship between the velocity and physical measurement to confirm index in selecting the Yili horses, and discussed to select the appropriate index selecting the Yili horses in different condition. According earnings we calculated IIPA, and connected the breeders with owners using the subsection physical measurement (SPM) and IIPA. Data from:1.the agonistic performance, earnings, physical measurement of Yili horse in the Shenzheng Derby.2.Mensurated 19 SPMs of 24 Yili horses in the Urumchi equestrianism club. Using DPS statistical software analyzed the relationship between velocity and basic physical measurements, SPM. The results showed that there were correlation (P<0.05orP<0.01) between the velocity and physical tall, chest circumference, cannon, age. In the SPM, there were positive correlation (P<0.05) between the velocity and neck length, scapular length, shoulder bone length, femoral bone length, tibiae length, and negative correlation(P<0.05)between the velocity and shoulder obliquity, femoral obliquity, hipbone obliquity. Using factor analyse there were three main factors in the SPM: traction factor, sustain factor, impetus factor, then using Clustering Analyse divided 24 Yili horses into four sorts: excellent, good, middling and bad. The results of the RSPM showed that only the appropriate RSPM could gain the full out velocity. Using RSPM educed regress equation (P<0.05), and according this equation can forecast the velocity of Yili horse. The results of IIPA showed that:87 Yili horses exceeded the mean100, 25 Yili horses exceeded120, 4 Yili horses exceeded 140.Both breeders and owners could use the IIPA and SPM as criterion in selecting, dealing, washing out Yili horse. Thus they could facilitate each other to breed horse with excellent agonistic performance.更多还原
