1. Based upon the analyses in the floristic elements of the three genera (Suaeda,
Salsola and Zygophyllum) in different regions we can see that the genesis of our desert
floras in these regions is very much diversified. The flora of Songaria is similar to that
of the Middle Asia, while the Hosi Corridor seems to be a transitional area very close to
Alashan and also related to the Tarim Basin in floristic elements. Thus, we may classify
the desert floras into three parts: the flora of Songaria, of Alashan including the Hosi
Corridor and of the Tarim Basin including the Tsaidam Basin. The ages and approa-
ches in their formation are different.
2. There are plenty species but no or rare endemics in Songaria. In spring there
are a number of ephemeral plants. The variation of aspect is evident. The vegetation
cover is abundant. The floristic elements are developed from the flora of Middle Asia
and it was formed in Quaternary period.
3. The floristic elements of the Tarim Basin are poor, but there are not few en-
demics and the distribution of the endemics is much limited. They are of the charac-
teristics of relic species. Therefore it was formed in the Tertiary period and developed
in Quaternary period. The elements are related to the Mediterranean flora.
4. There are a large number of endemics and many endemic monotypie genera in
Alashan. They represent the flora formed in Tertiary period. Although it is of a special
style, it relates both to the Middle-Asian and the Mediterranean flora.
5. The historic causes for the formation of the different floras lie chiefly on: (1)
The rise of the Tibetan plateau and mountains strongly changed the climatic and edaphic
conditions and in the long course of evolution some species survived or even developed,
while the others deteriorated or even died out from the flora. (2) Because the circum-
stances of transgression or regression of the Tethys were different in these regions. (3)
The mountain-making movement, the transgression and regression and the fluence of
glaciation, all the mutation of these associated factors modified the climatic zonation and
then the plant species changes followed, new species formed and migration of floristie
elements occurred. (4) Songaria is the nearest region to the then Sibirian glacier, so the
frozen injury to the flora might be the greatest. (5) In the Glacial period the descension
of snow line in Songaria was greater than that of the Tarim Basin, so the frozen injurymight be greater. 相似文献

随着经济的快速发展,人们对于自己的生活越来越关心。近几年来,关于年轻人结婚问题的各种报道、艺术作品、影视作品等也越来越多,从中浮现出了一些社会问题,值得深思。为了探讨上述社会状况所反映的社会性别意识的变化与发展,进行了一次社会调查。从2014年4月11日开始,到4月18日结束,调查了广大社会青年对于未来伴侣的心理预期,共收集了251份有效问卷。为了让调查对象地域范围更加广阔,并节约成本,方便收集,采用了网络问卷的调查方式。通过对这次调查结果的分析、总结,我们发现:随着社会发展,社会性别意识所发生的一些改变。 相似文献

生态语言学视野下地方高校大学英语课堂教学的困境与对策 总被引：1，自引：0，他引：1
生态语言学视角下大学英语课堂教学是一个完整的微观生态系统。大班教学已经成为当今中国高校大学英语课堂教学的主要组织形式,它给课堂教学带来了许多新的问题和挑战,进而使大学英语课堂教学长期处于生态失衡的困境。针对目前地方高校中大学英语教师、学生、教学信息以及课堂环境等之间存在的失衡问题,提出有效利用生态学语言学原理和观点来分析课堂教学生态各因素的作用和联系,通过增加师资投入,提高教师教学能力和专业素质;缩小大班人数规模,开展分级和分类教学;完善课程设置,综合各教学方法和模式;优化课堂内外教学环境等相应的改革建议与对策,促使课堂教学生态因素间相互和谐互动、协调进化,促进地方高校大学英语课堂教学生态系统的良性循环和可持续发展。 相似文献
