Discipline progress of mineral mapping of gold deposit in China     

JIANG Yonghong 《东北亚地学研究》2013,(4):192-200

Sanjiang and Jiaodong areas are the important gold regions in China. The gold mineralization is cor- related with the Mesozoic faults and its derivative faults in the granite or the contact zone between granite and base rock. The mineral mapping is one of the important approaches of prospecting mineralogy. The temporal and spatial band distribution of mineral, mineral combination and mineral typomorphism features are natural regularity rules, but this kind of band feature is sometimes hidden and thus in need of mineral typomorphism re- search and mapping to disclose this band feature and to serve for the prospecting of mineral. The changes of the mineral typomorphism feature are often embodied in the ＂ through＂ mineral, the typomorphism features of the through mineral change like the gradient toward the ore body, and the changes of the features are most obvious and strongest toward the orebodies. The new American mineralogy mapping indicates the weak change of the mineral composition or structure will lead to the change of the shape and wave length position of the specific ab- sorbent feature. Australian experiment lab investigation has held the reason of a series of mineral. The progress achievement of the remote sensing and computer analysis technology now permits a direct comparison directly between the lab and remote sensing data, so the good feature database of the experiment light spectroscopy can serve for drawing of the spacial distribution and remote sensing material. Mineralogy mapping raised the exten- sive emphasis in the international earth arena.  相似文献

陈虹  冯海峰  王永昕  李蕊  宋富喜  闻明 《国际地震动态》2012,(7):25-30

向遭受严重自然灾害的国家或地区提供人道主义紧急支援,是各国军队在和平时期的重要使命。目前中国军队还没有成建制地出国参加过重大自然灾害的国际救援。本文介绍了联合国重大自然灾害国际救援行动协调工作机制、联合国框架下的军队资源参与灾害救援的工作机制。结合印尼地震海啸、海地地震等灾害中各国军队救援的情况,对我国军队将来参与国际重大自然灾害救援,在法律、预案和工作机制准备方面进行了分析,并提出了建议。  相似文献   

海外土地利用规划中的公众参与及其启示   总被引：2，自引：0，他引：2  

陈美球  魏晓华  刘桃菊 《地域研究与开发》2008,27(6)

公众参与是国际上土地利用规划的一个基本原则,公众参与不仅平衡了公众利益与土地产权主体权益的关系,而且为规划的实施打下了良好的基础.从公众参与的地位与作用、公众参与的制度化建设、公众参与的行为与积极性等方面对海外土地利用规划中的公众参与进行了分析总结,并结合我国的土地利用规划要求,提出要从调动公众参与积极性、加强制度化建设、改进公众参与方式方法等方面推进土地利用规划的公众参与,从而提高我国编制规划方案的质量.  相似文献   

非洲的移民汇款及其对国家发展的作用     

丁金宏 《世界地理研究》2008,27(3):26-36

近几十年,全球汇款流在稳步增长并越来越成为发展中国家财政发展的重要源泉。汇款成为家庭收入中稳定的一部分,并组成了发展中国家第二大资金流——处于外国直接投资（FDI）之后,海外开发援助（ODA）之前。在撒哈拉以南非洲地区,流动工人的汇款成为财政发展以及救助穷人的财政服务的重要主题。本论文分析撒哈拉以南非洲地区迁移人口的汇款及其作用,并以马里作为重点研究对象。研究结论是,汇款在国家收入中占有重要比例,并将继续对个人家庭和社区提供重要支持,应该鼓励当地引导汇款促进基础设施发展和收入产生。  相似文献

Global virtual-land flow and saving through international cereal trade     

Jingqi Zhang  Naizhuo Zhao  Xingjian Liu  Ying Liu 《地理学报(英文版)》2016,26(5):619-639

With intense urbanization and sustained population growth, securing food production with limited land sources has increasingly become a pressing issue. Based on an analysis of international cereal (i.e., barley, buckwheat, maize, oats, rice, rye, sorghum, soybean, and wheat) trade and differences in yields of the cereal between export and import countries over the period of 2007 to 2011, we explore the great potential of land saving through the international cereal trade. By ‘land saving’, we refer to the reduced global total of lands required to produce a necessary amount of cereal when cereal is exported from a country with relatively large yield of the cereal to a country with relatively small yield of the cereal. Our scenario analysis suggests that international cereal trade would help mitigate the shortage of domestic arable land for many island countries (e.g., Japan) and countries in the arid Middle East and North Africa (e.g., Syria and Morocco). Furthermore, international cereal trade has the potential to generate ‘land saving’ of 50,092,284 ha of land per year, which is roughly the size of Spain. Drawing upon the definition of a similar concept — virtual water (Hoekstra and Hung 2002), we define virtual land as the area of land resources used for the production of goods. Through introducing the concept of virtual land, we believe land resources that are traditionally considered as stationary resources can flow with anthropogenic socioeconomic activities. The largest virtual-land flows (> 3,000,000 ha/year) exist between the United States (US) to China, Brazil to China, the US to Japan, the US to Mexico, and Argentina to China. However, not all virtual-land flows necessarily result in land saving. Thus, more endeavors are needed to plan the virtual-land flows for a larger land saving at the global scale.  相似文献   

Great Powers and Geopolitical Change     

Carl T. Dahlman 《The Professional geographer》2013,65(2):285-286

Abstract

Most traditional segregation measures, such as the index of dissimilarity D, fail to distinguish spatial patterns effectively. Previously proposed spatial measures modifying D suffer from several shortcomings. This article describes a general spatial segregation index based upon the concept of composite population counts, which are derived from grouping people in neighboring areas together to account implicitly for spatial interaction of groups across unit boundaries. The suggested spatial index can overcome the disadvantages of previous indices and can assess the spatial extent of the segregated clusters. The results offer a more comprehensive depiction of spatial segregation of a region.
