The spatial-temporal distribution of NPP along NECT and its response to climatic change were also analyzed. Results showed that the change tendency of NPP spatial distribution in NECT is quite similar to that of precipitation and their spatial correlation coefficient is up to 0.84 (P.01). The inter-annual variation of NPP in NECT is mainly affected by the change of the aestival NPP every year, which accounts for 67.6% of the inter-annual increase in NPP and their spatial correlation coefficient is 0.95 (P.01). The NPP in NECT is mainly cumulated between May and September, which accounts for 89.8% of the annual NPP. The NPP in summer accounts for 65.9% of the annual NPP and is the lowest in winter. Recent climate changes have enhanced plant growth in NECT. The mean NPP increased 14.3% from 1980s to 1990s. The inter-annual linear trend of NPP is 4.6 gCm^(-2)a^(-1), and the relative trend is 1.17%, which owns mainly to the increasing temperature.
结果表明:(1)NECT样带植被NPP的空间变化趋势同降水量的空间变化十分相似,由东到西逐渐降低,二者在空间上的相关性达到了0.84 (P.01),说明NECT样带的植被NPP在空间分布上主要受水分趋动:(2)NECT样带植被NPP的年际变化主要是由各年份夏季NPP的变化造成的,夏季对NECT样带植被NPP的年际增长贡献率最大(67.6%),二者之间的相关性达到了0.95 (P.01);(3)NECT样带的植被NPP积累期主要发生在5-9月份,这5个月的NPP占了全年NPP总量的89.8%,整个夏季(6-8月份)的NPP占了全年的65.9%,冬季(12-2月份)的NPP最低,基本为0;(4)近19年来的气候变化促进了NECT样带的植被生长,从1980年代到1990年代,NPP显著增加,年代际相对增长率为14.3%,平均年际绝对增长趋势为4.6 gCm^(-2)a^(-1),相对增长趋势为1.17%,这主要是由温度升高引起的。

It indicated that the annual runoff of the main and tributary of the Yarlung Zangbo river had an obvious decline trend during 1960s and reached the minimum in 1980s, since then, the annal runoff increased and a relatively wet season occurred in 1990s.

ABSTRACT After the ebb-tide of the May 4th Movement, the Chinese modern thoughts and literary circles went from relative unity towards diversity Up to the 1930's, behind the spirit transformation at the end of the twenties, Chinese modern intellectuals began to relocate and redesign their own outlooks on life and literary ideal The Lunyu School, which was led by Zhou Zuoren and Lin Yutang, mostly appeared as leisure humorous essays in some journals, such as Lun Yu, Ren Jian Shi and Yu Zhou Feng which was edited by Lin Yutang It formed an unique landscape at that time This thesis focused on the Lunyu School as the main object of my study I investigate the Lunyu School by putting it into the vertical orbit of changes of the thoughts and literary circles after the May 4th Movement, and by comparing it with the mainstream of Left-wing and other literary schools in the thirties Through the exploration of Lunyu School's political and social thoughts, literary ideas and aspects of prose creation, I pursue the life choice of some free intellectuals in the thirties, and draw psychological outline of an age of intellectuals, which was very complicated and attractive during that specified time and space When we reconsider the rights and wrongs, the merits and demerits, and the gains and losses in theory and creations of Lunyu School intellectuals, any oversimplified study method would be of"no avail but the waste of mind"Unless ample estimation of their own complexity and contradiction is made, furthermore subtly delineates quite a lot of originates which caused these complexity and contradiction, the research will not be valuable In face of the whizzed coming Left-wing movement in literature, Lunyu School acted as a reconsideration in literary modernity such reconsideration is a layer of thinking They introspected intellectuals'essential mind and enlightened reason, querying the impulsive, swift and fierce ideological trend, judging by value in the relations between individuality and society, individuality and era, literature and politics.
五四落潮后,中国现代思想界、文学界由相对统一走向分化,至二十世纪三十年代,现代知识分子经由二十年代末期的精神蜕变,开始重新定位和设计自己的人生观和文学理想。以"京兆布衣"周作人为精神领袖、以林语堂为主帅的论语派,以幽默闲适小品文相号召,在林语堂主编的一系列刊物《论语》、《人间世》、《宇宙风》上聚集,南北呼应,造成了当时文坛的一种独特景观。本论文以论语派为研究对象,将其放在五四以后文学界与思想界变动的纵向轨迹上,放在与三十年代左翼主流话语的颉颃及与其它文学流派的比照中加以考察,通过对论语派政治社会思想、文学观念及散文创作诸方面的探讨,追索三十年代一部分自由知识分子的人生选择,勾划出他们在一个特定时空里复杂又极具魅力的心理轮廓。学术界对论语派中一些主要作家已有较深入的研究,但迄今为止,尚无从整体上对这一文学流派作宏观研究的专著,而陈旧的理论视界又往往阻碍了对论语派的重新评价。

The studies of McCarthyism in America have gone through three stages. From 1950s to the middle of 1970s is the starting stage. The prosperous stage which I called is from the middle of 1970s to 1990s. In this period, great achievements have been made and some relevant problems have been studied. After 1990s, though the passionate of the studies of McCarthyism has relatively passed, it is still a focus the scholars paid attention to.
美国史学界对麦卡锡主义的研究可分为三个阶段。20世纪50~70年代中期是起步阶段。20世纪70年代中期~90年代初期取得重大成果,相关问题的研究在这一时期展开,可以说是对麦卡锡主义研究的繁荣阶段;20世纪90年代以后对麦卡锡主义研究的热情相对减弱,但仍是学者们关注的焦点。

A major part of my favorite are the 70s sneakers. Taiwan started to produce NIKE around the 80. Evalue based on the production in that period, I would say kicks from US factory are more tend to be broken by the cause of the damp. Shoes from Taiwan, Japan and other country don't have such problems.

Then the sustainable development of Qitai artificial oasis was discussed. Researches showed that the oasis development has gone through three phases: The first was harmonic stage before the middle of 20, the oasis developed according to water resources. The second was unharmonic stage from 1950's to 1980's because of unreasonable policies, that is cultivated area enlarged rapidly and water resources exploited backward. As a result, land output was lower, and environment destroyed heavily. The third stage is after 1980's, the new fragile balance between oasis and its environment was established on the base of the more and more ground water utilization.
研究认为奇台人工绿洲人地关系发展经历了三个阶段:第一阶段是20世纪50年代以前,&以水定地&的相对协调发展时期;第二阶段是20世纪50-80年代人地关系发展失衡时期,人工绿洲迅速扩张,水资源开发滞后,耕地因缺水灌溉而成为低产田,环境破坏严重,人地发展失衡的原因是政策因素;第三阶段是20世纪90年代以来人地关系脆弱平衡时期,决定其平衡的因素是不断增加的地下水开采量。
