Abstract: Canopy is the first part contacting with the external environment and light of fruit tree, and aslo the direct channel for fruit tree photosynthesis and respiration. The canopy morphalogical characteristics of fruit tree can not only directly build up the rich appearance of fruit tree, but also indirectly reflect the growth status and yield potential of fruit tree. This paper summarized various  measuring technique and analyzing methods proposed by domestic and foreign scientists specific for canopy morphological features, and prospected the major objectives of future research, so as to provide helpful references for  relevant personnel to further develop studies and application on canopy morphological characteristics.

Key words: canopy of fruit tree, morphological characteristics, measuring technique, mathmatical model

摘要： 冠层是果树最先接触外界环境与光照的部位，是果树光合作用和呼吸作用的直接通道。果树冠层的形态特征不仅直接塑造了果树丰富的外观造型，同时也间接反映了果树的生长状况和产量潜力。综述了国内外研究者提出的针对果树冠层形态特征的多种测量技术和分析方法，并对今后果树冠层形态特征分析的主要研究目标进行展望，以期为相关人员进一步开展果树冠层形态特征研究和应用提供有益的参考。
