For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.

为建立植群亚模型,首先依「整合大量样区资料,由下而上的低阶植相聚类」之途径,设计建档程序及转档程式,成功整并不同来源之585个样区资料,但因样区数目不足且分布不均,分析结果未能显示出台湾完整的植群类型;故转循「预先设定植群类型,由上而下的高阶形相分类」之途径,经参考他国植群分类系统及台湾、东亚植群分类研究报告,订定分类原则及架构,提出4阶层之潜在植群形相分类方案:(1)寒原、森林2类群系纲;(2)亚寒带、冷温带、凉温带、暖温带、亚热带5类群系亚纲;(3) 8类群系组表徵优势植群之叶片的物候与形态;(4) 16类群系说明其水分境制及优势分类群;此方案统一处理了过去各种有关植群划分之纷岐名制,方案之各阶植群类型亦即本研究之植群亚模型。

The results demonstrated that MC1R gene of bird was relatively conserved. The results of phylogenetic analysis showed that consanguinity relations between mule duck, anas platyrhynchos and branta bernicla, anser caerulescens, anser canagica were close.The status of them were confirmed on zoologyl by means of molecular method.

可见禽类的MC1R 基因编码区序列具有高度的保守性;系统进化分析表明,半番鸭、北京鸭与雪雁、黑雁、皇雁亲缘关系相近,从分子角度验证了它们在动物学分类上的地位。

Band differencing is feasible in water and irrigable field, but it couldnt monitor the changes of whole land use and its precision is the lowest. For the mufti-temporal composite method, it is difficult to choose the exact regions for change detection. Based on the previous accurate classification result, the post classification comparison method gets the best result compared with the other two methods, but also with the hand-on mistakes.

图像差值法对河流水面和水浇地的监测效果比较好,但对所有地类监测结果不令人满意,精度较低;多时相波段复合分类法中,变化土地类型训练区的确定较困难;分类后比较法是在前面土地信息准确提取的基础上进行的分析,精度较高,监测结果图也一目了然,是土地利用动态监测的一种有效方法,但它是在自动识别分类基础上进行的比较,传递了分类产生的误差。

Classical tragicomedy is the cristal of Chinese culture, and best represents the Chinese culture spirit. But regretfully Chinese dramatists followed the Western footsteps, put most of their energy onto the classical tragedy and neglect the study of classical tragicomedy. They classified many classical tragicomedies into the category of tragedy. It brought about the confusion in the classification of Chinese classical drama.

古典悲喜剧是中国文化的结晶,最能代表中国文化精神,遗憾的是我国戏剧界往往步西方的后尘,集中精力研究古典悲剧,忽略了对古典悲喜剧的探讨;又因为对古典悲喜剧的价值认识不足,有意无意地将许多悲喜剧划入悲剧范畴,造成我国古典戏曲分类上的混乱。

As a result, it is convenient for the recognition system to use the simple linear classifier to segment the sample space, so that the accuracy and distortion invariant ability can be easily achieved. The classification structure of a bifurcating tree is utilized to decompose the classification problem of multi-classes to the multi-stage classification of two classes, which simplifies the design of the classifier, and improves the searching efficiency as well. A gray-scale analysis based method for extracting features from optical correlation result is proposed.

提出了二叉树鉴别分类方法,在使用同类图象的多个典型畸变样本训练识别系统的基础上,利用鉴别分析方法优化各类图象的特征向量在样本空间中的分布,不仅有利于同时提高系统的准确性和抗畸变能力,而且便于采用简单的线性分类器来划分样本空间;利用二叉树分类结构,将多类样本的分类问题分解为多级二类样本的分类问题,不仅简化了分类器的设计,而且提高了搜索效率。

Although a certain correlation with the morphological classification based mainly on the characteristic of tubercles on the ripe fruit skin,the range of classification by RAPD was more detailed than that of morphological classification.

结果表明,大多数种质相似系数在55%~80%之间,说明他们之间的亲缘关系较近;在相似系数为0.61的水平上,30份海南荔枝种质被分为4组,与以龟裂片特征为主要分类依据的形态分类有一定的相关性,但是RAPD分类比形态分类的分类范围更细。
