P in Shule River Alluvial Fan Oasis in Gansu subsidized by CNSF. Through field geological and environmental observations and sampling, quartz OSL dating, organic carbon ~(14)C dating, as well as analysis of TOC,grain size and Pollen assemblage of the samples from ten sediment profiles in front fine grain sediment zone of the Shule River Fan, the results obtained as follows:(1)The vegetation evolution history on Shule River Alluvial Fan and circumjacent since about 13 ka B.P. could be divided into 6 phases: about 12.1-13.1ka, a sparse coniferous and broadleaf trees - shrub grassland, cold and wet climate; 9.2-12.1ka, shrub grassland, temperature rising but precipitation and humidity getting down; 5.8-9.2ka, sparse forest with the most flourish shrub grassland under the optimal climate; 4.3-5.8ka, coniferous and broadleaf mixed forests -shrub grassland, temperature rising slightly and getting dry; 4.3-2.8ka, grass vegetation and climate became more dry; 2.8-2.3ka, coniferous forests -shrub grassland, precipitation and temperature getting down, but a higher relative humidity.

本文依托于&甘肃疏勒河冲积扇5万年来古天气环境与古水文演化&项目，以疏勒河冲积扇为研究对象，通过对疏勒河冲积扇扇缘细土带全新世古天气和古水文演变进行了20余个剖面的观测和取样、石英OSL和~(14)C测年、粒度组成和TOC分析以及孢粉鉴定，获得了以下成果和熟悉：(1)距今约13ka年来冲积扇和周边植被演化经历了6个阶段：约13.1～12.1ka，以针叶林为主的针阔混交林～灌丛草原，天气冷湿；12.1～9.2ka，灌丛草原，气温升高，降水量较低；9.2～5.8ka，疏林灌木草原，植被茂盛，温度和降水最佳；5.8～4.3ka，以针叶树为主的针阔混交林～灌丛草原，气温较高，降水减少；4.3～2.8ka，草原植被，天气变干；2.8～2.3ka，针叶林～灌木草原，降水减少，温度降低，相对湿度有所增加。

The results are:(1) The higher of altitude,the less of soil acidity in soil C horizon at Dinghushan;(2) There are more NH4-N,total K,available K, exchangeable K,exchangeable Na,exchangeable Mg and the content of exchangeable cations in lateritic red soil at low altitude than those in yellow soil at high altitude;(3) With increasing altitude,the contents of sio2 and Mn decrease,and the concentrations of this two minerals in lateritic red soil are higher than those in yellow soil.

结果为：（1）鼎湖山土壤剖面C层随着海拔梯度的上升，土壤酸度降低。（2）鼎湖山位于海拔低的赤红壤的NH4-N，全钾，速效钾，交换性Na，交换性钾，交换性Mg和阳离子含量比位于海拔高的黄壤的对应养分含量要高。

They not only occur in deep ocean basins such as in the central North Atlantic where they were deposited below CCD, but they extend up the continental slopes and rises, such as in the Alps, including the Gampu area , in the Carpathian Mountains (Austria, Slovakia, Poland, Romania), in Spain, in Turkey and in the Exmouth Plateau (Legs 122 and 123) in northwest Australia.The Upper Cretaceous reddish marlstones in Italy are particularly similar to the Upper Cretaceous Chuangde formation red beds in the Tibetan Himalayas. In summary, the Upper Cretaceous redbeds have several characteristic as follow:(1) very low TOC, only 0～0.3%;(2) wide distribution throughout the Neo-Tethys, from north Atlantic to the west, to Exmouth Plateau to the east;(3) Sedimentary environment of the red beds varied from oceanic basin, to slope/rise, to outer shelf. Most comment is pelagic and hemipelagic.

床得组泥灰岩〓含量0.26～5.62％，远远高于奥地利和意大利红层0.45～0.82％，并出现金属元素高含量，平均达926ppm，以高含量Ba、Cu、Zn、Cr、Ni、Th等元素为特征；2）床得组红层〓相对于定日地区同期海相碳酸盐〓整体负向偏移量达2.0‰，而在其床得组红层内部〓自下而上一直攀升，自-1.5‰～0.0‰之间上升到0.0‰～1.0‰之间；定日贡扎剖面相当于江孜床得组红层的Santonian-Campanian期，〓也出现一弱负向偏移，偏移量达-0.8‰；3）红层内锶同位素〓比值为最低值，同期定日地区也出现锶同位素低值；4）床得组部分层段的泥晶灰岩出现丰富的有孔虫，其中尤以浮游有孔虫最为繁盛，与江孜地区临近的浅海陆棚相的定日—岗巴地区此时期出现自Cenomanian-Turonian界线生物绝灭后的生物辐射期。
