北美自由贸易区竞争政策特征初探

北美自由贸易区竞争政策是继欧盟竞争政策之后的一种新型竞争政策合作模式，是当今区域经济集团竞争政策较理想的合作典范。与欧盟竞争政策相比较，其呈现出抽象性、避免法律真空现象产生、处理竞争争端方式的特殊性、具体规定的模糊性以及层次单一性等特征，其中抽象性、避免法律真空现象产生及处理竞争争端方式的特殊性．比较适合大多数区域经济集团的特点，宜应效仿，而其具体规定的模糊性和层次单一性，应在日后制定的区域经济集团的竞争政策中加以完善。     

The discovery of early Permian reef belt in east Kunlun and its significance

The early permian reef belt is distributed in the southern side of eastern Kunlun, north area of Qinghai-Tibet Plateau. The core-reef facies of thc reel extends from Tuosuo Lake to Huashixia. Lots of reef breccia was found at the southern slope of the mre-reef belt, and to the north of the reef belt there is back-reef limestone. Cacisponges, hydrozoa, bryozoa,Tabulozoa, Tubiphytes and red algae are the main frame-building organisms.Archaeolithoporella, laminated blue-green algaes,Tabulozoa andTubiphytes played a role of binding or encrustating. There are many kinds of epibiont in the mf, including brachiopod, gasterid, foraminifera, echinoderm and simple coral. The type and the characteristics of the reef-building organisms in eastern Kunlun and Animaqing are basically thr same as those in the south of Chi     

Discovery and character of the Kunlun-Yellow River Movement

Based on geomorphological, tectonic and sedimentary data, a Kunlun Yellow River Tectonic Movement has been recognized in 1 10-0 60 Ma B.P. This tectonic movement, which leads to uplift of the Qinghai_Xizang (Tibet) Plateau from 1 500 to 3 000-3 500 m, is periodic, abrupt and changeable in the movement rate of uplifting and slide slipping.     

中国黄土区东亚古季风气候与冰期气候对比研究

研究了中国黄土区冰期气候与季风气候记录;进行了黄土磁化率与大洋δ１８Ｏ曲线对比,并且将黄土组合—古土壤组合与冰期－间冰期气候进行了比较。结果表明：黄土组合与古土壤组合记录了冰期气候与间冰期气候;中国黄土—古土壤堆积是全球冰期—间冰期气候变化与东亚古季风气候变化共同作用的结果。

渝西学院后山山林植被物种多样性研究

本选取渝西学院校园后山(黄瓜山)山林植被中6种主要森林类型的19个样方，通过比较这些类型的物种丰富度和Shannon指数，揭示了这些类型物种多样性的差异．结果显示：1)各森林类型乔木层、草本层物种丰富度低，灌木层物种丰富度较高；2)各森林类型的Shannon指数同物种丰富度具有不同的表现规律；3)常绿针阔混交林与落叶阔叶林具有特殊的物种多样性垂直结构特征；4)物种恒有度分析表明，星湖校区山林植被为人工林，景观简单，连续性强，存在明显的环境梯度．     

Impact of the closure of Indonesian seaway on climate: A numerical modeling study

Using a global OGCM and its relevant coupled ocean-atmosphere GCM with the contemporary, 6 MaBP and 14 MaBP oceanic topography, respectively, a series of numerical experiments are implemented in order to investigate the effect of the north shift of Australian continent on the tropical oceanic circulation, especially the formation of the western Pacific warm pool. The numerical experiments of the individual OGCM forced by the modern atmospheric circulation indicate that the closure of Indonesian passage results in warming in the tropical Pacific Ocean and cooling in the tropical Indian Ocean; furthermore, it also results in change in source of the Indonesian Through Flow (ITF) water, e.g. ITF mainly originates from the south Pacific at 14 MaBP, but it mainly originates from the north Pacific now. The coupled model shows similar results as the individual OGCM qualitatively.
