应用地球旋转力学方法评价金属矿、油气田的远景(英文)

文章叙述地质构造的新旋转概念,它可以解释地质构造激活的实质。每一次地质构造激活产生某些断裂系统,沿着这些断裂,地壳块体会发生一定的位移,并伴有一些地质现象产生。每一断裂系统的形成产生该系统特定的金属成矿条件,此规律性可用于金属矿预测。沉积盆地前景研究表明,沉积盖层中含碳氢化合物的局部构造仅与基底某些特定断裂系统的激活相关,用综合地球物理方法可揭示这种相关性的具体形式,并进行盆地前景评价。

The Bo-Tai Line: Establishing the concepts of a balanced regional development line and a national development backbone

Promoting regional coordinated development strategy is one of the important strategies in the new period of China.Faced with the reality of unbalanced and insufficient regional development in China,it is objectively necessary to construct one or more main axes supporting the coordinated and balanced development of regions to become the identification line representing the pattern of coordinated regional development.The results show that the Bo-Tai line,the northwest-southeast axis connecting Bole of Xinjiang and Taipei of Taiwan,can be built into national development backbone line and regional balanced development line,just perpendicular to Hu Line.In 2016,the area of southwest half and northeast half of Bo-Tai Line accounts for 60％:40％,while the population accounts for 45％:55％,the economic ag-gregate accounts for 40％:60％,the per capita GDP ratio accounts for 44％:56％,the popu-lation density ratio accounts for 38％:62％,the economic density ratio accounts for 32％:68％,and the urbanization level ratio accounts for 48％:52％.The main average indicators are gradually tending to balanced development pattern.Further analysis shows that Bo-Tai Line is a strategic shoulder pole connecting two core zones of"the Belt and Road",and is the peaceful reunification line of China's national tranquility and Taiwan's return.Bo-Tai Line is also a solid line supported and connected by comprehensive transportation channels and a Pipa type symmetrical line for the development of cities and urban agglomerations.It is the backbone of the two-way opening up and the linkage development line between land and sea.It is also an important dividing line that promotes the coordinated development of the eastern,central and western regions,and addresses the imbalance and inadequacy of regional de-velopment.Bo-Tai Line plays an irreplaceable strategic role in promoting the coordinated and balanced regional development.It is suggested that the construction of Bo-Tai Line should be included in the national development strategy,and the development strategic plan of Bo-Tai Line should be formulated to fully release the multiple potential functions.We should build three strategic support points:the northwest endpoint,the central strategic node and the southeast endpoint;carry out a comprehensive scientific investigation of the Bo-Tai Line,and strengthen the scientific cognition and publicity;promote China's development in a higher-level,higher-quality,more coordinated,safer and more civilized direction.Let Chinese know about the Bo-Tai Line,let the world know about the Bo-Tai Line,and let the Bo-Tai Line truly become the backbone of the great rejuvenation of the Chinese nation.     

比较沉积学概念体系的厘定与重构

近代沉积学的诸多进步都是由比较沉积学推动的,它对沉积学的发展有重要意义。目前,其被广泛应用于相模式的推断和沉积相带、储层及其非均质性的预测。比较沉积学是利用比较对象所选变量的时空展布建立模型,再利用模型推断预测被比较对象因变量时空展布的沉积学分支学科。它是根据比较沉积学类比原则,在自生旋回、他生旋回识别的基础上开展的或然性推理。完整的比较沉积学工作过程必然存在2个步骤——比较建模和推断预测。其研究方法包括相模式分析法、几何形态分析法、沉积物载荷分散体系分析法和模拟重构法4种,这些方法多与层序地层学方法联合使用。本文根据比较沉积学的原理和方法综合分析了历年来的典型成果。未来比较沉积学将开展更多与边界条件有关的研究、多尺度统一解释的研究,进一步加强量化,提高预测精度的研究。

水资源承载力的研究进展与趋势展望

水资源承载力是水资源安全战略研究中的一个基础课题,是水资源安全的基本度量。它是涉及社会、资源和环境系统的一个指标,用来反映水资源系统对社会经济持续发展的支撑能力,是水资源研究领域和可持续发展研究领域中的一个重要课题。在实践领域中则是区域水资源开发利用对策研究的基本依据。因此,通过时区域水资源承载力的研究,可以更好地理解水资源系统对社会发展的支撑作用,认识人口、资源与环境协调发展的关系,更好地实现社会可持续发展。在分析和总结现有资料的基础上,对水资源承载力的概念内涵作了进一步的探讨,并对其量化方法和存在问题进行了论述,最后展望了水资源承载力研究趋势。     

蒙贝低涡类环北京暴雨过程分型研究

利用天气观测资料、NCEP/NCAR再分析资料对1998—2008年发生的20例蒙贝低涡导致的环北京暴雨过程进行了分型研究。依据环流特征和天气系统配置,将该类暴雨过程分为两脊一槽型、阻塞型和低涡—副高南北对峙型。其中,两脊一槽型是斜压性较强的冷涡暴雨过程,天气和次天气尺度强迫均对暴雨发生产生影响,水汽来源于对流层低层西南气流的输送。阻塞型具有明显的局地对流暴雨特征,由两高之间宽广低压带上活跃的中尺度对流系统引发,高低空急流区产生的次天气尺度强迫是中尺度对流系统的触发因素之一。低涡—副高南北对峙型是低涡底部发展中的高空槽与北抬西太平洋副高相互作用产生的系统性暴雨过程,这一相互作用常强迫产生西南低空急流,为系统性暴雨的发生提供了充沛的水汽供应。     

Cartography in the Context of Sciences: Theoretical and Technological Considerations

Abstract

In an introductory theoretical way, the authors attempt to place cartography into the general context of sciences. Based on the traditional definition describing cartography as a science, technique and art, its defined scientific role in the development of geographic thinking is analysed. This approach corresponds to the procedural method in epistemology. Cartography is, according to a general model in science, classified considering the fact whether its sources of origin of the concepts, its principles and postulates are genuine or derivatives from other disciplines. After comparative statements between Cartography and Geography, an analysis of all environmental sciences with reference to the use of technologies is carried out.
