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。

Based on the summarization of metadata, DL and DLIO, this paper illustrates the essentialness of metadata"s application in DLIO, the organization structure of DL"s information resources, metadata standard design and metadata creating in DL. After this, it introduces and analyzes the application of DC, MARC and Chinese metadata standard in DLIO and gives an applied case.
本论文以元数据概述和数字图书馆及其信息组织概述作铺垫，对元数据应用于数字图书馆信息组织的必要性、数字图书馆信息资源的组织结构、数字图书馆元数据标准的选择与设计及元数据的编制进行了详细阐述，之后，又对数字图书馆信息组织中广泛使用的DC元数据、MARC以及具有代表性的国内专门数字对象中文元数据标准进行了介绍与分析，并辅之以上海数字图书馆元数据方案的实例。
