中国地市卫生资源需求测度及其时空格局研究

测度地区卫生资源需求是实施以需求为导向的卫生资源空间配置的前提.综合考虑地区卫生资源需求决定因素及空间相互作用,构建卫生资源需求指数,分析2000年—2010年中国卫生资源需求在地市之间的分布及变化.结果发现,中国卫生资源需求自西向东呈“高－低－高”的总体空间格局.西部的青海、西藏、新疆和川西地区主要因为居民健康需要水平高,卫生资源需求中高值地市连片分布,形成青藏地区高值集聚区和以藏中为核心的中国西部卫生资源需求热点区域.东部沿海地区主要因为卫生服务可及性高,卫生资源需求中高值地市集中分布,形成环渤海、长三角和珠三角高值地市集聚区和以苏浙沪为核心的中国东部卫生资源需求热点区域.中部地域整体上居民健康需要和卫生服务可及性较低,连片分布卫生资源需求低值地市,其中广州、武汉、成都等部分省会城市和豫北地区因卫生服务可及性较高,川云桂黔地区因健康需要水平较高而成为卫生资源需求中高值区,形成以甘川陕晋豫鄂湘为主的低值地市集聚区和以甘陕鄂湘赣为核心的中国卫生资源需求冷点区域.     

Palaeolake and palaeoenvironment between 42 and 18 kaBP in tengger desert, NW China

Comprehensive field investigations and laboratory analyses show that palaeolakes, including fresh- mesohaline water Megalake Tengger and other semi-con- nected, isolated water bodies, during late Pleistocene covered an area of more than 20000 km², which is more than half of the Tengger Desert in NW China. Stratigraphic correlation and chronological evidence indicate that before ca. 42000 aBP the area was more arid. The palaeolakes started to develop around 40000 uncal. ¹⁴C aBP but until 37000 ¹⁴C aBP their scope was limited. High water levels established from 35000 ¹⁴C aBP lasted until 22000 ¹⁴CaBP. Lake levels regressed between 22000 and 20000 ¹⁴C aBP but transgressed from 20000 to 18600 ¹⁴C aBP. Subsequently, water level declined further and the Megalake Tengger finally desiccated at around 18000 ¹⁴C aBP. Megalake Tengger possessed a fresh-mesohaline water property, implying that the regional precipitation increased significantly. During the period of Megalake Tengger, the climate was warmer-humid than present. The annual rainfall was 250 to 350 mm more than that of today and the temperature was 1.5 to 3.0℃ higher.     

Geochemistry and petrogenesis of Jurassic high Sr/low Y granitoids in eastern China: Constrains on crustal thickness

The Jurassic high Sr/low Y granitoids in eastern China are characterized by high Sr/Y (27—166) and La/Yb (14—66) ratios, low abundance in Y (6—21 μg/g) and Yb (0.5—2.0 μg/g), comparable with those of adakites defined by Defant et al. Thus, they were recently considered as adakitic rocks by some researchers. Compared with the typical adakites in circum-Pacific margins, however, these high Sr/low Y granitoids have higher K₂O (-3.5%) but lower Al₂O₃ (-16.0%) as well as lower Mg^# (-38) and δ Sr_N (-1.23) values. Furthermore, they show relatively flat HREE patterns with Y/Yb values of -10 close to the chondritic value. These geochemical characteristics indicate a residue mineral assemblage of hornblende, garnet and plagioclase for these high Sr/low Y granitoids melt. Thus, they were generated by partial melting at 9—13 kbar (30—45 km in depth), similar to the Archaean high-Al TTG rather than the modern adakites. Generation of these high Sr/low Y granitoids cannot be considered as evidence for a thickened crust (>50 km) and/or the presence of the “Eastern China Plateau” in Jurassic.     

Quaternary high-resolution opal record and its paleoproductivity implication at ODP Site 1143,southern South China Sea

The correlation of opal content and MAR with oxygen isotopic records of benthonic foraminifera at Site 1143, southern South China Sea indicates that,since about 900 ka,the increasing opal content and MAR during the interglacial periods is inferred to reflect the bigher surface productivity ,for the intensified summer monsoon during the interglacial periods would result in the enhanced upwelling and nutrient supply,Time-sequence spectral analyses of oxygen isotopic record ,opal content and MAR at intervals of 0-900 ka reveal that the changes of surface productivity were dominantly forced by the variations of the earth orbital cycles.

克林顿执政时期经济领域的对华政策问题探析

克林顿执政时期，美国在寻求中美经济领域合作的同时，为了政治目的和单方经济利益，在最惠国待遇，贸易逆差知识产权问题上屡屡向中国发难造成中美经济领域的摩擦。只有本着相互尊重，互惠互利的原则，这些问题才可以得到解决，并且为中美政治领域的更进一步合作奠定基础。     

New fossil elaterids （Insect： Coleoptera： Polyphaga： Elateridae） from the Middle Jurassic of Inner Mongolia, China

A new genus with a new species of fossil elaterid, Paraprotagrypnus superbus gen. et sp. nov., from the Middle Jurassic Jiulongshan Formation in Daohugou Village (N41°18.979′, E119°14.318′), Shantou Township, Ningcheng County, Inner Mongolia, China is described and illustrated. The genus Paraprotagrypnus belongs to the family of Elateridae, subfamily of Protagrypninae and tribe of Protagrypnini. Some primitive characters of the new genus and new species shed light on the ages between the Jiulongshan Formation in Inner Mongolia and the Yixian Formation in the western Liaoning Province of China. The habitat of the new species is briefly discussed.

全球化语境下中国大众文化防火墙的构筑

在全球化时代,中国大众文化与西方大众文化接触日益频繁,从而加大了东西方大众文化的相互激荡和冲突。由于在成长发展上的后发性,中国大众文化成为西方大众文化“化中国”的重要途径,面对全球化的压力,中国大众文化不能退却畏缩,而应该以积极的“中国化”姿态来迎接挑战,用中国自己的大众文化构筑防止西方大众文化“化中国”的防火墙。
