Responses of growth and interactions between mangroves and Spartina alterniflora across tidal elevation gradient
红树林是生长在热带、亚热带海岸潮间带的一类木本植物群落,具有很高的生态价值。在全球气候变化和人类活动的双重影响下,互花米草入侵中国东南沿海红树林,威胁乡土红树植物的更新和生长。为了更好地理解全球变化背景下互花米草入侵对红树植物生长分布的影响,判别其种间相互作用沿环境梯度的变化情况,我们在漳江口实验区开展实验,通过野外水位梯度控制平台,在较小的空间范围内实现水位控制,对比研究不同潮位梯度下红树植物秋茄、无瓣海桑和互花米草对淹水时间的响应机制,结合刈割和保留互花米草处理,研究互花米草对红树植物的相互作用强度与潮位梯度的相关关系,解析沿潮位梯度下生物和非生物因子对红树植物早期更新、生长过程中的作用。...Mangroves is a kind of woody plant community grown in the tropical and subtropical intertidal zones, which has high ecological value.

Peaches in the Kojiki
The Kojiki, Japan’s oldest book of history, was finished in 712, in the context of the nation’s foundation. In it, Amaterasu Ōmikami’s father Izanagi, the greatest god of the Yamato dynasty, is helped by three peaches. And Emperor Jinmu, the founder of the Yamato dynasty, is guided by a red crow. What is the significance of the peaches and the red crow in the Kojiki?Both the peaches and red crow were borrowed by the authors of the Kojiki from ancient Chinese mythology, where they are symbols of the sun god. In this fashion, Chinese sun worship is incorporated into this historical account of the Yamato dynasty. It was a strong desire of the authors of the Kojiki to acquire the grace of a sun god like that of the great dynasties of China. Moreover, the ambition of the authors of the Kojiki to assimilate the learning of Chinese civilization inspired them to use language that might even surpass it in excellence
A Design that Crossed the Sea : the Dragon in Ceramics
We find the same culture of the dragon in Japan and China. But in Japanese ceramics, there are no vivid dragons as in Chinese ceramics. It means that Japanese comprehension of ceramics and dragons is different from that of Chinese. The dragon is of Chinese origin and it was the symbol of the emperor. The manufacture of ceramics had sacred significance in ancient China. It has always been connected with the throne. Therefore, the Chinese preferred to draw the dragon on ceramics. However, for Japanese, the manufacture of ceramics had no sacred significance as in China. The concept began when it was brought over to Japan. The dragon is not the symbol of the Japanese emperor and the throne. It is the god of water and a terrible serpent. Therefore, the Japanese did not like to draw the dragon on ceramics. The disappearance from ceramics of the dragon is one of the distinctions of Japanese culture that is an adoption and invention of Chinese culture
Tea Bowls and Cultural Conflict
日本には八点の国宝茶碗がある。八点のうち、南宋時代に焼造された天目が五点を占める。曜変天目三点、油滴天目一点、玳皮天目一点である。これらの天目茶碗は、生産地の中国の地には残されていないのに、なぜ日本に残っているのか?日本の国宝と中国の天目とは矛盾しないのか?天目を求め続ける日本人の情熱はいったい何か? 曜変天目は中国の陶工にとって「窯変」であり、不吉な異変であるため、窯から出るなり消されてしまった。だが、日本の茶人にとっては、「窯変」ではなく「曜変」である。華麗な珍奇な唐物茶碗として愛され、代々尊ばれてきた。 また、玳皮天目は煩雑な文様や派手な釉色を持つため、平淡を好む宋の文人に好まれなかった。日常雑器として使われ壊され棄てられた。だが、日本に渡った玳皮天目は、唐物としての価値が茶人に認められ、今日まで伝わることができた。 油滴天目と禾目天目は、焼造された当時は宋代の文人にも珍重された。しかし、点茶法の衰亡と泡茶法の台頭により、中国では不要なものになった。そこで、商人の活躍によって日本に持ち込まれるようになった。 天目茶碗が日本に伝世され、中国で消えたのは、中国文化と日本文化の異質性によるものだった。日本人が中国産の天目茶碗を日本の国宝に入れて何らの矛盾を感じないのは、日本人が、その矛盾自体を日本文化の特牲だと考えるからである。天目茶碗を再現しようとする日本人の情熱には、中国文化への憧憬と対抗意識があった。憧憬があるから中国文化を借用し、対抗意識があるから新しい創造へとつながった。言い換えれば、天目茶碗の中日における存在の相違から、日本文化が抱えた大陸への絶えることのない憧憬と対抗意識と、それを基盤にした創造性を読み取ることができる。黒楽茶碗は、宋代の天目茶碗の借用から生まれた日本人の創造であった
Feature Article : Expression of Nationalism : Personal Thoughts of Odano Naotake : Borrowing in, and the Creation of, “Tobijinzu”
Among Akita Ranga (Western-style paintings from Akita) are two works of “Tobijinzu” (Illustrations of Chinese Beauties) attributed to Odano Naotake. As Akita Ranga Western-style paintings, why do they borrow their subject matter from China? Also, although they borrow Chinese subject matter, why were such peculiar works as “Tobijinzu” created which do not feature in actual Bijinga (pictures of beauties) from China? What kind of thoughts did Naotake seek to commit to these pictures?Naotake, in order to express his own thoughts in contrast to Gennai, borrowed China’s Kan Fujin and Li Qing Zhao (Ri Seisho). He re-styled the borrowed material by using newly adopted Western painting techniques, and following his particular sensibilities. This gave birth to Kan Fujin and Ri Seisho illustrations: Bijinga of a type unknown in China, and unique to Akita Ranga. In other words, borrowing in, and creation of, Tobijinzu constituted a union between the Japanese spirit (Naotake’s thoughts and sensibilities), Chinese subject (material from Chinese painting) and Western art (rules of perspective and shadow)

论“断交”后台湾当局“双边协定”的处理
1949年10月中华人民共和国成立以来,各国陆续与台湾当局断绝"外交关系"。为推行其所谓的"实质外交"策略,台湾当局在与他国结束官方关系后,对于双方间的既有"协定"总体上采行的是通过协商以尽可能维持"协定"关系的处理态度。实践中,也确有部分"双边协定"得以继续实施。值得注意的是,其中某些"协定"延续的途径既和台湾在国际法上的地位不符,又与各国政府同中国政府的建交公报精神相违背。为在国际社会强调一个中国,维护两岸关系和平发展,中国政府应对台湾与"断交国"之间逾越一个中国原则的行径有所防范。国家社会科学基金项目“台湾对外签订协议的法律问题研究”(16BFX186
