海底沉积和泥土

海洋底部是沉积物长期集聚的地方。海底沉积可以是陆源矿物,生物沉积,火山沉积以及洋底发生化学作用的产物。     

能源问题

第十届世界能源会议①专业委员会很重视公元2000年以前世界能源需求量的预测。其预测数字同利用设想模型所得到的结果是很接近的。利用设想模型所得到的2020年以后的预测数字,只应看作是2020—2100年期间的初步预测。     

地域生产综合体在区域经济体系中的地位(关于方法论的探讨)

本文试图主要从经济区划和地域规划的角度来确定地域生产综合体在国民经济结构中的地位。不能不看到,经济学家和经济地理学家们对这个问题的观点有很大的分歧.     

挪威的河流污染与区域环境政策

本文提出一项区分挪威河流水质和测定影响水质诸因子的系统方法。详述了挪威一些流域的水质和潜在污染指数。挪威地广人稀。每平方公里平均人口密度仅有13人。即使在人口最稠密的奥斯陆地区每平方公里平均人口密度也只有113人。挪威的居民区集中于海岸与河谷。     

苏联社会经济地理学的任务

最近十年来,做为一门科学的地理学已经发生了重大的变化。现在,社会经济地理学形成了一种关于社会空间形式的知识体系。经济一地理这门学科的分化同时又是综合的趋向是和地理学研究当前强调与经济学、生态学与社会学方面的联系有关的。     

解释自电异常用的诺模图

关于自然电场法最早的一篇理论著作是1928年彼得洛夫斯基写的.他研究了地下的极化球体的电位分布,并且证明了地表电位随余弦函数变化.海兰德的垂直极化球体异常解释方法就是基于彼得洛夫斯基的理论.De Wette(1948)研究出一种方法,利用球体来模拟矿体.Yungul(1950)改进了彼得洛夫斯基的方法,提出了消除地形和区域场影响的方法.Murthy和Reedy介绍了解释球状、棒状和倾斜板状极化体自电异常的方法.     

Integrated Radiolarian and Conodont Biostratigraphy of the Middle to Late Permian Linghao Formation in Northwestern Guangxi, South China

The Permian radiolarian zones and their correlations with conodont zones or other chronostratigraphic schemes are still under debate. In this study, four genera, 21 species and two subspecies of radiolarians together with one genus and six species of conodonts were recovered from the Linghao Formation cropping out at the Longwangpo (LWP) section, northwestern Guangxi, South China. Six radiolarian interval zones and one abundance zone are recognized in the section, namely in ascending order, the Follicucullus scholasticus, Albaillella cavitata, A. protolevis, A. levis, A. excelsa, A. triangularis Interval zones and A. yaoi Abundance Zone. They are correlated with the Clarkina dukouensis, C. guangyuanensis and C. orientalis conodont zones recognized at the same section. Based on our data, the F. scholasticus Interval Zone and the lowermost part of A. cavitata Interval Zone are recognized to be upper Capitanian age, whereas the four Albaillella Interval zones are of Lopingian age (Wuchiapingian to the late Changhsingian). Two previously known Changhsingian radiolarian zones, namely the A. triangularis and A. yaoi Interval zones, should be extended down to the uppermost Wuchiapingian in this studied section.     

Challenges at the early stages of the environmental licensing procedure and potential contributions from geomorphology

Defining impact significance is the main technical task that influences decision-making during the Environmental Licensing Procedure(ELP).The ELP begins with screening to determine potentially signif-icant impacts of the proposed project.Scoping then follows to address any interventions deemed worthy of attention in the production of an Environmental Impact Assessment(EIA).This will include consider-ation of relevant landforms and geomorphological processes.However,preliminary assessments of envi-ronmental impacts often lack the scientific robustness to procure substantive and transactive effectiveness.This review presents an examination of the established practices of screening and scoping while highlighting the foremost challenges to improve the technical grounds of the ELP.The analysis of screening and scoping practices stresses the need for novel methods that ensure the sequential reasoning between their criteria while improving the preliminary evaluation of impact significance.Reducing the inherent subjectivity of discretionary judgment requires scientific methodologies that acknowledge the interaction between the natural system and human interventions,which has been addressed by geomor-phological research.The knowledge consolidated in this review opens the gate to explore the compatibil-ity between the United Nations strategy of Ecosystem Approach(EA)with the ELP through a novel geomorphological interpretation of the EIA.Therefore,this diagnosis demonstrate that screening and scoping practices would benefit from reliable methods that balance the precautionary principle with the efficient character required in the ELP.
