Biogeography of spiders (Araneae: Arachnida) on the islands of the Southern Ocean

The araneofauna of the extreme Southern Hemisphere is highly impoverished and disharmonic. Four dead anthropogenic immigrant spiders have been collected from Antarctica while only 115 verified species from 26 families are reported on the islands of the Southern Ocean. Cluster analysis of the verified Southern Ocean species distribution data identifies a weak, but distinct, Neotropical/South Atlantic association together with robust South Indian and South Pacific biogeographic clusters. These groupings, largely attributed to vicariance and/or endemism, contain little evidence of post-Pleistocene dispersal. Indeed the 14 records of anthropogenic origin suggest that the pace of recent human-mediated introduction has been at least 30 times more rapid than that of Holocene natural dispersal.     

谭嗣同与宋恕--以《仁学》为中心

《仁学》的主旨是要在文明层面回应西方冲击，树立一个取代程朱理学的思想典范，标志着近世中国思想体系向近代的蜕变。谭嗣同在同时代的变法思潮中，融合了康有为与宋恕的变法思想，在其师刘人熙等人影响下，立足于王船山、魏源的思想传统，吹响了近代中国民族、民主双重革命的号角。谭嗣同在北游访学前后思想发生了决定性的变化，其主因是受到宋恕等人的思想影响。     

太行山南端野皂荚群落数量分析

在野外调查的基础上,应用TWINSPAN和DCA对太行山南端野皂荚植物群落进行了分类与排序研究.结果表明:TWINSPAN将野皂荚植物群落划分为6个群丛,分别是野皂荚+荆条-中亚苔草+荩草群丛、野皂荚+荆条+小叶鼠李-中亚苔草+荩草群丛、野皂荚+荆条+毛黄栌-冰草+中亚苔草群丛、野皂荚+荆条+小叶鼠李-白羊草+冰草群丛、野皂荚+荆条+小叶鼠李-中亚苔草+荩草群丛和野皂荚+毛黄栌-中亚苔草群落.样方和种的DCA排序结果表明,样方的DCA第一排序轴表明决定群落分布的是坡向,从阳坡过渡到半阳坡;种的DCA第一排序轴主要反映了物种生活型的变化,即由中生植物为主过渡到以旱中生植物为主.样方和种的DCA的第二排序轴生态学意义不明显,主要是研究区域尺度较小,群落异质性不明显所致.     

Turbidite deposition in the southern South China Sea during the last glacial: Evidence from grain-size and major elements records

High-resolution grain size and major element geochemical measurements were performed on the marine sediments of Core MD05-2895 to help understand the formation of turbidite sequences. Grain-size results show that these turbidite sediments contain more coarse sediment grains than normal marls. The coarse sediment grains are mostly derived from relict sediments on the Sunda Shelf. Relict sediments are composed mainly of quartz, feldspar, tephra and a few titaniferous or ferruginous heavy minerals. Corresponding to the concentration of these minerals, increases in Si/Al, K/Al, Ti/Al and Fe/Al ratios are observed in the turbidite layers. As all the observed turbidite sequences were deposited during the last glacial, the occurrence of these turbidity events is implied to be closely related to instabilities in sea-level-induced sediment supply. We suggest that deposition of sediment particles from a single turbidity current is usually controlled by a counterbalance between gravity and buoyancy, with the interaction of individual grains being of minor importance.     

基于GIS对南疆区域城市化综合水平的差异与城市组团发展研究

建立了南疆城市化综合水平指标体系,通过熵值法确定了各个指标的权重,并进行了排序。计算出2008年南疆地区42个县市的人口城市化水平、经济城市化水平、社会城市化水平和城市化综合水平,从地州和南疆角度进行了比较。把南疆地区城市化综合水平划分为四个等级,分析了不同等级所在县市的城市化发展的差异性,并用ArcGIS软件实现了空间上差异的图形化。根据陆大道提出的“点轴”理论原理,结合南疆地区城市发展的客观事实,提出以库尔勒市为中心的“库尔勒组团”,以库车为中心的“库一拜组团”,以阿克苏市为中心的“阿克苏组团”,以喀     

南朝《采莲曲》与唐朝《采莲曲》比较分析

采莲是中国诗歌中的重要题材之一,南朝和唐朝时期的文人大量创作《采莲曲》,由于创作主体不同、所处的时代环境不同,唐朝《采莲曲》在对南朝《采莲曲》的继承中有所发展。根据收集的材料比较分析两个朝代《采莲曲》的相同点和不同点,简约探讨其原因。     

南华北盆地上寒武统白云岩岩石学与地球化学特征及其成因探讨

南华北地区上寒武统白云岩发育,按结构-成因划分为:晶粒白云岩、残余粒屑白云岩及藻(层纹石、叠层石)白云岩等.应用岩石学与地球化学方法,对其成因进行了探讨.晶粒白云岩伴生矿物少,偶见黄铁矿,阴极发光为中-弱橘红色光,Sr含量较低,该种白云岩为埋藏白云岩;残余粒屑白云岩中含有生物碎屑、内碎屑、藻屑等颗粒组分,白云石矿物表面污浊,阴极射线下呈中弱亮度橙红色,锶值低,接近于零,为成岩阶段早-中期浅埋地下混合水潜流带环境生成;藻白云岩具有纹层、藻叠层等构造,白云石细小,阴极射线下暗红褐色,锶值高,反映交代介质仍然是超盐度咸水,为水上蒸发环境下同生—准同生白云岩.     

建立“南太行＂旅游圈的对策思考

在综合研究河南省太行山旅游资源概况的基础上,提出“南太行”旅游圈的概念,分析了建设南太行旅游圈的优势与劣势,认为建立南太行旅游圈的资源非常丰富并具有同质性,建设旅游圈的基础牢固,合作前景光明．同时,找出了影响建立南太行旅游圈的因素,然后从管理体制改革、旅游法规体系建设、拓宽投融资渠道、提高从业人员素质、推出南太行旅游名牌、强化南太行整体概念和建立决策支持系统等角度提出了相应的对策．
