The canopy structure and leaf morphological characters of 4 sugarcane genotypes at different leaf layers on seedling were studied by using CI-100 plant canopy instrument and CI-203 area meter instrument. The results showed the leaf morphological parameters, canopy structure and radiation transmission at different leaf layers were notably different among different genotypes. The variation of Ila, Amfi, Dl at different leaf layers were mainly caused by the leaf width at relevant position. The variation of K at different leaf layers was related to Amfi and Dl. The variation of Td（transm. coef. for diffuse penetration）had significant correlations with Ila, Amfi and Dl. The variation of Tr（transm. coef. for radiation penetration）had significant correlations with Dl, leaf width and the ratio of leaf length to width. The variation of Par had significant correlations with Ila, leaf area, leaf width and the ratio of leaf length to width.

摘要利用CI-100数字植物冠层分析仪和CI-203叶面积分析仪测定了4个甘蔗品种不同叶位层的冠层参数和相应叶位叶片的形态特征，结果表明：不同基因型不同叶位层间叶片形态、冠层空间结构和冠层辐射特征存在显著差异，不同叶位层叶面积指数、叶簇倾角和叶分布的变化主要由冠层内不同叶位叶片叶宽的变化引起，而不同叶位层消光系数的变化主要与叶簇倾角和叶分布有关；散射光透过系数的变化主要与叶面积指数、叶簇倾角和叶分布有关，直射光透过系数的变化主要与叶分布、叶宽、长宽比有关，光合有效辐射的变化与叶面积指数、叶面积、叶宽、长宽比有关。

By using the kernel function, the input space is mapped to a high dimension feature space where the data are expected to be more separable, the initial centroids in the feature space are selected by applying the KRA algorithm, and the large and small clusters are partitioned and the outliers can be split from the large clusters iteratively after the kk-means clustering. As a result, the audit data can be clustered better. Secondly, the closed sequential patterns mining algorithm CloSpan is improved according to the restrictions that is composed of the axis properties and reference properties.
