清末社会转型与广东“民变”

清末十年，广东从传统社会向近代社会加速转型，官绅对城乡控制能力大为减弱，社会普遍动荡不安，造成民怨沸腾，“民变”蜂起。“民变”作为人民群众自发的反抗斗争，既打击了清王朝在广东的基层统治，促进革命形势的高涨，但同时又有很大的破坏性和局限性，不宜颂扬过多。     

清文刍议

清是清人留下来的一份珍贵学遗产。它所反映的社会生活面之广阔，爱国主义精神表现之强烈，对封建统治黑暗揭露之深广，渴望变革的呼声之高亢，对历朝历代古创作成就的总结、继承、创新和发展，都达到了一个新的高度。     

Speciation of the genus Arthricocephalus Bergeron, 1899 (Trilobita) from the late Early Cambrian and its stratigraphic significance

The genus Arthricocephalus Bergeron, 1899 is revised, and Halipanktos Balker & Peel, 1997 is suggested here as a senior synonym. The subgenus Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al., 1974 is considered as a separate genus. Of the 20 previously assigned species of Arthricocephalus (Arthricocephalus) Bergeron, 1899, Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al., 1974, Arthricocephalus (Euarthricocephalus) Ju, 1983 are lumped into eight species. The speciation trend of Arthricocephalus and Arthricocephalites is demonstrated based on their stratigraphic occurrences. It not only enhances the resolution of the biostatigraphic zonation in the uppermost Lower Cambrian, but also represents a potential candidate to define the Duyunian stage. The base of the stage is suggested at the first appearance datum (FAD) of Arthricocephalus chauveaui Bergeron, 1899 within the evolutionary lineage from Ar. jiangkouensis Yin in Yin & Li,1978 to Ar. chauveaui in a global scale.     

安徽省产业转移中的问题与对策分析——基于梯度转移理论的视角

梯度转移理论作为产业转移理论之一主张发达地区加快发展,通过产业和要素转移的方式带动低梯度地区发展。安徽省作为长三角地区产业转移的第一梯度区域,其承接长三角地区产业转移存在着必然性。安徽省应围绕支柱产业,提升承接产业转移的配套设施;政府应将其职能转变为指导市场,集中处理市场失灵;在承接产业转移时,应做好环境影响评估,防止环境污染。

Stage characteristics for the development of late Quaternary paleosols in the Yangtze Delta area

The late Quaternary paleosols in the Yangtze Delta area developed in the period of 25 000-12 000 aBP. Phytolith ratios (value A) of contents of fan, square and rectangle types indicating the warm and humid climate to those of bar, hat and point types indicating cold and dry climates decrease upwards overall on profiles of the paleosols, suggesting that the climates turned from warm and humid to cold and dry. So, the paleosols developed mainly during the regression before the last glacial maximum. Changes of value A indicate no trend of warming, suggesting that the transgression was rapid after the last glacial maximum. The development of the paleosols exhibited obvious stages, which were controlled remarkably by transgression and regression : Ⅰ . Period of alternation of deposition and pedogenesis, which was from the occurrence of regresson before the last glacial maximum to the time when sea levels fell close to the lowest; Ⅱ . Exposure period with continual pedogenesis, which was terminated when the paleosols were drown in the post-glacial transgression; Ⅲ . Period of being drown and buried, the paleosols were buried by marine sediments, and reworked by early diagenesis.     

北京王府井东方广场遗址地层的沉积相与古地貌研究

通过对遗址地层典型沉积剖面和遗址地区150余个地层资料的对比分析,揭示了北京王府井东方广场晚更新世晚期旧石器人类遗址地层的沉积特征与沉积相类型,从而恢复了距今2.2万年前人类在此生存活动的古地貌面。研究表明,古人类曾活动于古冲积扇面的砂岛上,这是末次冰期间较温暖的间冰阶时期,是一个水流相对稳定的时期。还讨论了由于受较强的不稳定水流影响,使该文化层内有3140年没有人类的活动,认为该遗址是一个人类活动的临时营地。并且,在同一时期,人类可能来自周围的古冲积扇高地,或来自平原西部较早形成的高地貌面。以上的研究为北京平原晚更新世晚期人-地环境的重建和进行史前人类历史的研究提供依据。
