人类文化遗产信息的空间认识

人类文化遗产是人类历史的信息载体。航空航天和遥感技术、全球定位技术、地理信息系统、虚拟现实等技术的出现和广泛应用，为考古学研究开启了全新的科技之窗。提取这些历史信息，加以科学和历史的分析与处理，就可了解人类历史发展的轨迹、演变规律和历史的内涵。从全方位、多时相的四维角度去理解和重现人类文明历史的进程。     

青藏高原高寒草甸生态系统表观量子产额和表观最大光合速率的确定

高寒草甸是青藏高原广泛分布的植被类型,面积约1.2×106km2,位于青藏高原腹地的西藏当雄县即是典型分布区之一.以2003年生长季在当雄草原站用涡度相关法连续观测的CO2通量数据为基础,分析了净生态系统二氧化碳交换量(NEE)与光合有效辐射(PAR)之间的关系,及其表观量子产额(α)和表观最大光合速率(Pmax)在生长季中的变化特征.结果表明:白天的NEE与PAR之间符合很好的直角双曲线关系;α随生长季依次为草盛期>草盛初期>种子成熟期>枯黄期,最大为0.0244μmolCO2·μmol?1PAR,最小仅0.0098μmolCO2·μmol?1PAR;Pmax在草盛初期、草盛期、种子成熟期变化不大,平均0.433mgCO2·m?2·s?1(9.829μmolCO2·m?2·s?1),在枯黄期仅0.35mgCO2·m?2·s?1(7.945μmolCO2·m?2·s?1).青藏高原高寒草甸的α值与世界上其他的草原生态系统相比,明显偏小.     

A Preliminary Analysis of Relations Between Tectonic Deformation of Sedimentary Cover and Basement in Kuqa Depression

Study of seismic activity in the Kuqa area enables us to infer some possible active faults in basement from the epicentral distribution on different profiles. The relations between active faults in the basement and surface structures are analyzed and the difference between sedimentary cover and basement in their deformation characteristics and the genesis are discussed. The following conclusions have been drawn : ( 1 ) the epicentral distribution indicates that, the east Qiulitag and south and north Qiulitag deep faults in the basement correspond to the east and west Qiulitag anticlines, respectively. Moreover, deep faults also exist beneath the Yiqiklik and Yaken anticlines. It indicates that the formation of surface structures is controlled by deep structures; (2) A NE-trending strike-slip fault develops along the line from the western termination of Yiqiklik structure to Dongqiu Well 5 and a NW-trending active fault on the western side of Baicbeng. The two active faults across the tectonic strike are the main causes for tectonic segmentation of the Kuqa depression and possibly the cause for the middle segment (Kuqa-Baicheng) of the depression to be more shortened than both its eastern and western terminations; (3) The difference between the sedimentary cover and basement in their deformation characteristics depends mainly on the different properties of media between them.The lithospheric strength of the basement in the basin is fairly high, which determines the basement deformation to be mainly of brittle fracture seismic activity. While the strength of sedimentary cover is low, where there exist weak thin layers, such as coal and gyps. Under the effect of strong tectonic compression, the sedimentary rocks may undergo strong viscous or plastic flow deformation; meanwhile, an aseismic detachment may take place along the weak layers.     

Geology and Exploration of Oil and Gas in the Ordos Basin

The Ordos basin is rich in oil and gas resources. The structures in the basin are generally rather gentle. Most of the oil and gas pools already found are belong to the types of lithologic, lithostratigraphic and paleo-geomorphic with thin reservoirs. The geology of oil and gas and the generation and distribution of oil and gas resources in the Ordos basin is analyzed in detail in the paper. It is also pointed out in the paper that what direction should be taken in oil and gas exploration in the basin, and that the important role of the seismic prospecting technologies in the discovery of large oil and gas fields in the basin could not be replaced.
