山水画乃中国绘画之大宗,山水画理论也是中国学术史的重要组成内容。中华美学精神形之于绘画,也以体现在山水画上最为清晰。山水画历史久远,它产生于魏晋六朝时期,而宗炳的《画山水序》和王微的《叙画》两部山水画理论也产生在同时期,它的出现对前汉后唐两个时代艺术的总结和开拓起了转折与通筋舒络的作用,以自己鲜明的艺术特色丰富了早期的中国美术史,并对后世中国画和画论的发展产生了直接影响。 相似文献

《论语》是儒学和中华文化最重要的一部经典。汉后2000多年,儒学是中华文化的主干,而孔子是儒学的创始人,儒学的基本思想都在《论语》中,所以《论语》也被称为“中国人的圣经”。 相似文献

迄今为止的人类历史,都是脚踩在土地上写成的。而中国人,又是世界上最善于种地也最乐于种地的族群。会种地的民族,自然对土地看得最重,与土地的纠葛和牵绊也就格外悠远绵长。正如柏杨在《中国人史纲》所讲述的那样,"世界上再没有第二个民族像中华人这么喜爱耕种。中华人足迹所到之处,必然地会出现青葱的农田。一个中华人就是一棵树,离不开泥土,而且紧抓着泥土,根深蒂固。"人们吃土地,穿土地,生长在地上,归葬于土中。可以说,无数的先人在大地上舒展的个体命运汇集到一起,就是一部人与大地的故事集,就是一部厚重的华夏史。本期开始连载的《中华五千年国土资源风云录》的第一部——《青铜时代的土地战争》,是一段旨在梳理人与大地故事的文本。它从一个特别的角度,让我们得以窥见我们的先祖是如何去认识、了解和掌控土地资源的,它用尽可能忠于过往但又不失鲜活滋味的文字,为我们展现出惊心动魄而又趣味盎然的历史的另一面。沙场上的金戈铁马,宫廷内的权谋术数,闺房里的儿女情长……这些并不是历史的全部——人与土地的千古传奇,才更宏大,也更精彩。 相似文献

To investigate the relationship between volcanic activity and sediment record on regional and temporal scales, 158 surface
sediment samples were collected from the East China Sea Shelf to the northern Okinawa Trough (OT), and two cores recovered
in the northern and southern OT, respectively. Mineralogy, grain-size, and geochemical analyses of those samples show that:
1) volcanic glass, volcanic-type pyroxene, hypersthenes, and magnetite increase in sediment influenced by volcanic activity;
2) sediment grain sizes (and also silt content) increase in ash layers; and 3) the contents of Na2O and Zr are higher, while terrigenous elements, e.g., TFe2O3 and K2O, and biogenous compositions, e.g., CaO and Sr, are relatively lower in ash layers than those of non-ash layers. The distribution
of volcanic ash has three distinguishing characteristics: 1) volcanic ash is more abundant in the northern and central OT
than the southern OT; 2) volcanic ash increases from continental shelf to the trough; 3) the sediment during the last 12 000
a suggests stronger volcanic events than during 15 000–12 000 a. The eruptive locations, frequency, and volume of calderas
are among the most important factors controlling the distributions of volcanic ash. In addition, the main Kuroshio warm current
that extends northward probably impeded the diffusion of volcanic ash to the west and south in the OT. However, a southward
current probably carried some volcanic ash toward southern OT. 相似文献

Micromorphological analysis of soil structure under no tillage management in the black soil zone of Northeast China 总被引：1，自引：0，他引：1
The structure of the ＂black soil＂ in Northeast China has been greatly deteriorated by long-term intensive conventional mouldboard plow tillage （CT） practices. In this study, micro- morphological observation and image analysis of soil thin sections were conducted to evaluate the impacts of 21 years （1986-2007） of no tillage （NT） on soil structure as compared to CT in an experiment near Gongzhuling City, Jilin Province. Soil organic matter （SOM）, wet aggregate stability and saturated hydraulic conductivity （Ks） were also analyzed. Total SOM was not significantly affected by tillage systems, but fresher SOM was observed in the surface layer under NT. The aggregates under NT showed different hierarchies in the form of crumbs, and the mean weight diameter （MWD） of NT was significant higher than that of CT in the surface layer. Platy and blocky aggregates were frequently observed in the lower layers under CT practice. The compound pore structure with intertwined intra- and inter- aggregates pores under NT was well developed in a layer from 0-5 cm to 20-25 era. While under CT system, more inter-aggregate pores and fewer intra- aggregate pores were observed, and planes and channels were frequently found in the 20-25 cm layer, where maeroporosity decreased significantly and a plow pan was evident. The Ks values of NT weresignificantly lower at o-5 cm but significantly higher at 20-95 cm compared with CT, which showed the same trend with macroporosity. These results confirmed that long-term CT practice fragmented the tillage layer soil and compacted the lower layer soil and formed a plow pan. While long-term NT practice in the black soil region favored soil aggregation and a stable porous soil structure was formed, which are important to the water infiltration and prevent soil erosion. 相似文献

地名词典查询是地名校正、地名匹配等地名服务应用的重要基础,但是地名数量的快速增长使得词典查询性能面临严峻挑战。针对大规模数据环境中传统词典查询方法准确率不高且效率较低等问题,提出了一种顾及字符特征的中文地名词典查询方法（CGQM）。首先,查询具有相同字符特征的地名形成候选地名集合,同时构建单字索引提升查询效率;其次,依据字符数量特征比较查询地名与候选地名的差异,进一步过滤候选地名集合;最后,基于字符位置特征优化查询结果排序策略,使得结果排序更为合理。实验以全国地名词典为例,构建5组测试集进行CGQM方法与Lucene检索方法的对比分析。研究结果表明,CGQM方法对于增强地名词典查询功能、提升查询效率具有实际意义。 相似文献

The impacts of no-tillage (NT) and moldboard plough (MP) managements on infiltration rate and preferential flow were characterized using a combined technique of double-ring device and dye tracer on a black soil (Mollisols) in Northeast China. The objective of this study is to evaluate how tillage practices enhance soil water infiltration and preferential flow in favor of soil erosion control in the study area. The steady infiltration rates under NT management are 1.6 and 2.1 times as high as those under MP management in the 6th and 8th years of the tillage management in place, while the infiltrated water amounts under NT management are 1.4 and 2.0 times as high as those under MP management, respectively. The depth of methylene blue penetrated into NT soil increases from 43 cm in the 6th year to 57 cm in the 8th year, which are 16 cm and 19 cm deeper than those in MP soil, respectively. The results of morphologic image show that more biological macro-pores occur in NT soil than in MP soil. These macro-pores play a key role in enhancing preferential flow in NT soil, which in turn promotes water infiltration through preferential pathways in NT soil. The results are helpful to policy-making in popularizing NT and have the implications for tillage management in regard to soil erosion control in black soil region of China. 相似文献

Vertical distribution of soil nematode communities under conventional tillage (CT),no-tillage (NT) and fallow field (FF) treatments in the Lower Reaches of the Liaohe River was investigated at six soil depths (0-5 cm,5-15 cm,15-30 cm,30-50 cm,50-75 cm and 75-100 cm). The results show that total nematode abundance gradually decreases with depth,and the highest number of total nematodes is observed at 0-5 cm depth under NT and FF treatments. The number of fungivores and plant parasites is significantly higher... 相似文献

园林植物知识图谱可为顾及区域适应性、观赏性和生态性等因子的绿化树种的选型提供知识支持。植物描述文本的实体识别及关系抽取是知识图谱构建的关键环节。针对植物领域未有公开的标注数据集,本文阐述了园林植物数据集的构建流程,定义了园林植物的概念体系结构,完成了园林植物语料库的构建。针对现有Word2vec、ELMo和BERT等语言模型存在无法解决多义词、融合上下文能力差、运行速度慢等缺点,提出了嵌入ALBERT（A Lite BERT）预训练语言模型的实体识别和关系抽取模型。ALBERT预训练的动态词向量能够有效地表示文本特征,将其分别输入到BiGRU-CRF命名实体识别模型和BiGRU-Attention关系抽取模型中进行训练,进一步提升实体识别和关系抽取的效果。在园林植物语料库上进行方法的有效性验证,结果表明ALBERT-BiGRU-CRF命名实体识别模型的F1值为0.9517,ALBERT-BiGRU-Attention关系抽取模型的F1值为0.9161,相较于经典的语言模型（如Word2vec、ELMo和BERT等）性能有较为显著的提升。因此基于ALBERT模型的实体与关系抽取任务能有效提高识别分类效果,可将其应用于植物描述文本的实体关系抽取任务中,为园林植物知识图谱自动构建提供方法。 相似文献
