大陆法系国家通常规定国家租赁、法人破产、涉及因内国登记而发生的诉讼和内国国民的身份关系的涉外民事案件属于国家专属管辖权的范围 ;英美法系国家对当事人选择管辖法院的制度即协议管辖制度持肯定的态度 ,对专属管辖的规定反而不多。  相似文献   

Research and application of mineral resources assessment by weights of evidence model based on SIG     

Yuanyuan Chuai Keyan Xiao Yihua Xuan Shaobin Zhan 《东北亚地学研究》2006,9(1):109-114

Geological data are usually of the characteristics of multi-source, large amount and multi-scale. The construction of Spatial Information Grid overcomes the shortages of personal computers when dealing with geological data. The authors introduce the definition, architecture and flow of mineral resources assessment by weights of evidence model based on Spatial Information Grid （SIG）. Meanwhile, a case study on the prediction of copper mineral occurrence in the Middle-Lower Yangtze metallogenic belt is given. The results show that mineral resources assessement based on SIG is an effective new method which provides a way of sharing and integrating distributed geospatial information and improves the efficiency greatly.  相似文献   

云南西畴红石岩铅锌铜矿床喷流沉积成因的地球化学特征     

易友根 《福建地质》2014,(2):94-101

西畴红石岩铅锌铜矿床是滇东南地区首次在远离岩体外围田蓬组中发现的一处大型矿床,根据矿床地质背景,系统分析了红石岩铅锌铜矿床的地球化学特征,认为红石岩铅锌铜矿床的成矿元素具有明显的垂直和水平分带,容矿围岩的常量元素数据投影落入到热水沉积岩区域内,微量元素变化规律反映出与现代大洋热水沉积物相似的特点,稀土元素具有轻稀土富集的右倾特征,总量变化较大,但铅锌铜矿层中的稀土元素总量明显低于围岩,平均为66.16,与产于加拿大沙利文矿山的条带状富电气石热液沉积岩（57.85）相近,由此认为红石岩铅锌铜矿床是在特定的古构造古地理环境内形成的喷流沉积型矿床。  相似文献

浙江西部地区构造与岩浆活动频繁,区内分布有元古宙和古生代的铜矿成矿有利层位,北东向为主的深大断裂发育且多次活动,神功期和燕山早期的岩浆活动与成矿关系较密切。长期而复杂的地质演化、构造作用和岩浆活动为区内许多矿产的形成提供了良好的条件,铜、金、银等矿产的成矿条件较好。在分析研究区构造、地层、岩石、断裂等特点并在对浙江西部铜矿床的成矿规律深入研究的基础上,利用MapGIS 6.7和MORPAS 3.0软件平台提取构置了来自地质异常、成矿异常等多源信息的多个地质变量信息,将研究区划分为5 km×5 km的网格单元共1 755个,利用证据权法的数学模型对研究区铜矿资源进行预测,最终圈定了5个成矿远景区作为今后工作的重点区域。  相似文献   

大陆坡脚确定原则与方法          下载免费PDF全文

方银霞  李家彪  尹洁  刘为勇  唐勇 《海洋学研究》2022,40(2):1-9

大陆坡脚是大陆边缘的一个重要地形特征,是沿海国扩展其大陆架权利和划定其200海里以外大陆架外部界限的基础,也是大陆架界限委员会审议沿海国划界案时特别关注的重要技术参数。《联合国海洋法公约》第76条大陆架制度的制定源于典型的被动大陆边缘。但由于全球大陆边缘的多样性和复杂性,特别是后期构造活动、沉积作用对大陆边缘的改造与影响,海底地形地貌异常复杂多变,导致大陆坡脚的识别非常困难。加上各沿海国为获得最大范围的外大陆架,对大陆坡脚的相关规定进行有利于自己的解释,使得大陆坡脚的确定成了外大陆架划界中一个颇具争议的热点问题。本文基于对《联合国海洋法公约》和《大陆架界限委员会科学和技术准则》对大陆坡脚的规定,结合不同类型大陆边缘的地质特征和各沿海国划界实践,对陆坡基部区的确定、坡度变化最大之点的选取以及相反证明规则的适用性等问题进行了探讨。  相似文献   

一种信息量和专家证据权重法耦合的成矿预测方法     

陈广洲  徐晓春  汪家权 《测绘科学》2013,38(1):146-149

本文选取安徽石台县丁香地区,以铜多金属矿为例,分析该区的地、物、化、遥数据,选择7个预测变量进行成矿定位预测研究。利用客观成矿预测法-信息量法进行计算,得到成矿预测变量所占的信息量,归一化得到变量的客观权重,依据专家知识,获得上述变量的主观权重,随后,采用D-S证据理论将上述主、客观权重进行融合得到综合权重,并采用该综合权重结合专家证据权重法获得单元格的后验概率,制作成矿有利度的分级色阶图。预测结果表明:该法能有效地综合来自主、客观方面的知识,预测结果更加科学、合理。与单纯的信息量法、专家证据权重法相比,取得了更好的成矿预测效果。  相似文献

本文提出一种利用线性回归分析来指导成矿有利证据层筛选及最佳临界值获取的方法,并以桂西-滇东南地区锰矿为例,在多元地学空间数据库的基础上进行了基于线性回归的证据权法的矿产资源预测研究。实例表明,线性回归分析能利用成矿信息估计矿化分布的总体趋势,其回归分析结果能反映成矿信息与矿化分布的正负相关性,结合统计分析方法指导获取的最佳临界值,不仅具有地质意义,而且具有统计意义,能在证据图层二值化时最大限度减少信息丢失。  相似文献   

Prediction of hydrothermal copper,gold, silver and lead-zinc in northwestern Yunnan using weight of evidence model     

Jacob Kporfor  Chen Jiagou 《地球空间信息科学学报》2013,16(3):230-234

This paper discusses the application of the model in predicting for hydrothermal Cu, Ag, Au and Pb?Zn occurrences in northwestern Yunnan. Geochemical, lineament and lithology data were the selected recognition criteria. The mentioned criteria varied against 75 known hydrothermal occurrences; the geochemical data had a weight of (W+=1.2097,W?=?0.7481) being the maximum among the three and the rest lineament and lithology have (W+=0.7424,W?=?0.4496), (W+=0.3787,W?=?0.6243) respectively. The application was successful since the predicted results covers about 70% of the known deposits and predicted unknown areas.  相似文献   

The tropical forest in south east Asia: Monitoring and scenario modeling using synthetic aperture radar data     

《Applied geography (Sevenoaks, England)》2013

Tropical forests play a major role in storing large carbon stocks and regulating energy, and water fluxes, but such forest cover is decreasing rapidly in spite of the policy attention on reducing deforestation. High-resolution spatiotemporal maps are unavailable for the forests in majority of the tropical regions in Asia because of the persistent cloud cover and haze cover. Recent advances in radar remote sensing have provided weather-independent data of earth surface, thus offering an opportunity to monitor tropical forest change processes with relatively high spatiotemporal resolutions. In this research, we aim to examine the tropical deforestation process and develop a spatial model to simulate future forest patterns under various scenarios. Riau Province from central Sumatra of Indonesia is selected as the study area; this province has received much attention worldwide because the highest CO₂ emission resulting from tropical deforestation has been recorded. Annual time series PALSAR data from 2007 to 2010 were analyzed for forest mapping and detecting land cover changes. A spatial model was calibrated using the Bayesian method. Modeling parameters were customized for the local subregions that allocate deforestation on the basis of their empirical relationships to physical and socioeconomic drivers. The model generated landscape spatial patterns mirrored the possible locations and extent of deforested areas by 2030 and provided time-series crucial information on forest landscape under various scenarios for future landscape management projects. The results suggested that the current deforestation process is in a critical stage where some subregions may face unprecedented stress on primary forest costing rivers and forest ecosystems by the end of 2020. The perspective views of Riau Province generated by the model highlighted the need for forest/environmental planning controls for the conservation of environmentally sensitive areas.  相似文献   

Using moment invariants to analyze cluster shapes and hypothesize potential causes     

J.F. Conley 《International journal of geographical information science》2013,27(4):657-680

Although there are many algorithms and statistical tests to detect clustering of geographical phenomena, such as disease cases, the follow-up task of analyzing the cluster to explain its existence and mitigate the cluster is generally left to the researcher. These cluster detection methods are useful only for part of the process of identifying, understanding, and mitigating disease clusters. This research develops and presents a computer program that uses the information about the shape of the cluster to evaluate the hypotheses about potential causes. To achieve this, the shapes of the clusters are represented by image moment invariant statistics developed in the field of computer vision, and these shape statistics are compared against a database of moment invariants of shapes representative of several geographical processes, such as diffusion along roads and wind diffusion. Experiments using simulated data of different types of disease transmission were carried out, and the ability of the program to accurately classify the different types of diffusion demonstrates the viability of this approach to automated cluster analysis.  相似文献
