江西省崇义聂都瓦窑坑白钨矿区资源储量数据集

南岭是中国钨矿高度集中的地区。崇义县聂都章源钨矿（瓦窑坑白钨矿区）即位于南岭构造带之崇（义）—（大）余—（上）犹钨锡成矿区内。该矿床属于矽卡岩型钨矿。该矿区因合理规划矿山生产和办理采矿许可证延续之需,委托江西省赣州市地质队在充分收集以往地质资料的基础上,对矿权范围已发现矿体补充开展了部分勘查地质工作后编制了资源储量地质报告,并附有多张关于资源储量的数据表形成的数据集。数据集共包含七个数据表（.doc格式）,采用国家标准对矿区白钨矿的品位、资源储量、保有储量等进行了测试与估算,精度满足资源储量估算要求。数据集可对周边同类型矿床的资源储量评估做一参考,同时对研究矿床的分型与分带情况也具有参考意义。

蒙特卡洛模拟法在辽宁层控碳酸盐岩型铅锌银矿产预测中的应用

蒙特卡洛模拟法是一种概率抽样的方法,它是利用模型区内已知矿床资源量的分布曲线,通过抽样实验模拟出该区在某种概率意义下具有的资源潜力的方法。通过对辽宁省11个矿带、16个矿田层控碳酸盐岩型未知铅锌、银矿床(点)的资源潜力模拟,获得了省内层控碳酸盐岩型铅、锌、银的资源潜力。在模拟过程中所使用的评价方法及所应用的前提条件是成功的,其所获得的层控碳酸盐岩型铅锌、银矿产资源潜力是可信的。本文只讨论第Ⅳ矿带及第16矿田的资源潜力。     

空间信息统计学应用系统在广西大厂长坡区的应用研究

结合广西华锡集团的重点科技攻关项目“广西大厂矿田地质矿产数据库的建立与开发”选题,以空间信息统计学这一边缘交叉学科的理论为指导,以先进的VisualBaisc为开发工具,开发出了以Windows98或Windows NT为操作平台的“空间信息统计学应用系统——SISAS系统”。并重点介绍了该系统在大厂长坡区的运用,认为该系统的应用为研究矿体自然状态的三维空间特征提供了新的研究手段,并为描述具有空间结构的自然现象提供了一些新的思路。     

论矿床的分形性质

地壳中元素和矿化分布的不均匀性是一个普遍规律。从超大型矿床→大型矿床→小型矿床→矿点、矿化点（或高异常点）的分布，是近似于从有限稀硫分布逼近无穷多且无限稀硫分布。因此可以把矿床的分布看成是随机康托集（Cantordust）在空间上的分布。浙江中生代热液萤石、银、铅锌矿床的分形丛集分布存在于两个尺度范围内，分形丛集的分维数为0．196～0．40（1～20km）和1．161～1．219（20～750km）。矿床的频度—大小分布也是分形的，其储量分形分布的分维数为：萤石（中国）D=2．13；萤石（浙江）D=2．34；银（浙江）D=1．63；铅锌（浙江）D=2．27；钨（中国）D=2．16；铜（世界）D=2．55。我们认为，矿床储量的分形分布，对于各种标度的成矿作用可能是一个普遍性的特征。根据矿床的频度—大小分形关系，有可能对一地区大于某一指定储量的潜在矿床数作出预测。     

Cows versus rubber: Changing livelihoods among Amazonian extractivists

The livelihood strategies of former rubber tappers in the Amazon region are rapidly shifting from extraction of non-timber forest products to mixed systems based on agriculture and small scale cattle ranching. Using a combination of participatory methods and Geographical Information Systems, a case study in western Acre, Brazil explores how rubber tapper livelihood strategies may be changing, and the implications of these changes for land use and forest cover. Field (cattle pasture and agriculture) expansion and the decline of forest extractivism present challenges to many regional conservation and development projects such as sustainable settlement projects and extractive reserves seeking to develop forest-based livelihood alternatives to limit deforestation. Sustainability goals require researchers and policy makers to address the still experimental status of these forest-based organizational units, the heterogeneity and dynamism of extractivist livelihoods, and the necessary importance of small-scale cattle ranching for insurance and income generation among many former and current extractivists.

安徽省煤炭资源

安徽煤炭资源主要分布在淮南煤田和淮北煤田,为华北型石炭、二叠纪含煤地层;其次分布在沿江江南一带的皖南煤田,为扬子型晚二叠世龙潭组、早二叠世梁山组及早侏罗世磨山组含煤地层.以安徽省最新矿产储量简表(能源矿产煤、石煤)和第三次煤炭资源预测资料为依据,对全省煤炭资源已发现的资源量、现保有资源量及远景预测资源量作了全面论述.在清理煤炭资源数量的同时,提出了我国现行的煤炭资源分类系统存在的问题,并针对存在的问题和煤炭工业今后发展提出了建议.     

Harnessing Crowdsourced Data and Prevalent Technologies for Atmospheric Research

The knowledge garnered in environmental science takes a crucial part in informing decision-making in various fields,including agriculture, transportation, energy, public health and safety, and more. Understanding the basic processes in each of these fields relies greatly on progress being made in conceptual, observational and technological approaches. However,existing instruments for environmental observations are often limited as a result of technical and practical constraints. Current technologies, including remote sensing systems and ground-level measuring means, may suffer from obstacles such as low spatial representativity or a lack of precision when measuring near ground-level. These constraints often limit the ability to carry out extensive meteorological observations and, as a result, the capacity to deepen the existing understanding of atmospheric phenomena and processes. Multi-system informatics and sensing technology have become increasingly distributed as they are embedded into our environment. As they become more widely deployed, these technologies create unprecedented data streams with extraordinary levels of coverage and immediacy, providing a growing opportunity to complement traditional observation techniques using the large volumes of data created. Commercial microwave links that comprise the data transfer infrastructure of cellular communication networks are an example of these types of systems. This viewpoint letter briefly reviews various works on the subject and presents aspects concerning the added value that may be obtained as a result of the integration of these new means, which are becoming available for the first time in this era, for studying and monitoring atmospheric phenomena.
