直通车里快乐多——2008年部委政策信息对话会侧记

2001年,四川省隆昌县东方宾馆会议室,以中国国土经济学会副理事长、全国中小城市生态环境建设实验区专家委员会主任、中国科学院院士、中科院原常务副院长孙鸿烈为团长。一行16人的实验区建设考察团为隆昌县举行生态环境建设座谈会。中国国土经济学会常务理事、实验区指导委员会委员、国家林业局退耕还林工程办公室副主任李青松发言时提出了这样一个观点：成为实验区就如同搭上了县到部委的“直通车”,在如今的信息时代,

山东省按照“禁采区关停、限采区收缩、开采区聚集”的原则,合理调整开采布局,严格控制矿山规模,全力推进矿产资源开发整合。目前,已有97个重点矿区完成资源开发整合任务。     

我国矿山地质环境恢复补偿制度建立与完善探讨

当前,我国经济建设对矿产资源勘查开发需求越来越强劲,因开采矿产资源所造成的越来越突出的矿山地质环境问题不仅威胁到人民生命安全,而且严重地制约了国民经济的发展。因此,迫切需要加强矿山地质环境保护和恢复治理,这也与国家环境政策的要求相适应,而建立矿山地质环境恢复补偿制度（或机制）则是一项十分有效的制度保障。     

利用光学图像与雷达图像提取地质构造信息的IHS融合方法研究

光学图像和雷达图像的IHS融合方法是提取构造信息的一种较好的信息增强方法,这种方法既可以保留波谱信息,又可以增加图像的立体效果。本文以鄂尔多斯盆地杭锦旗—东胜地区一带为研究区,选用光学TM图像和雷达JERS图像进行了IHS融合处理,重点研究了光学图像波段的选取以及雷达图像的预处理过程,并在融合过程中注意通过光学TM图像和雷达JERS图像之间的直方图匹配,以降低其融合后图像的变化差异度,从而使此种融合方法更适用于研究区的构造信息提取。     

矿产预测中成矿信息的提取和强化

成矿信息的提取是矿产预测的重要手段,其方法的有效性直接影响到预测成果的可靠性。在成矿规律研究的基础上,有意识地干预模型的构成,突出与成矿有关的信息;抑制某些成矿意义不明显和属干扰的信息,有目的地使模型向反映成矿信息的方向逼近,提高模型与矿床实际赋存地质环境的吻合程度,均是成矿信息提取和强化的内涵。本文从研究实践中总结了先验约束模型和非先验约束模型的强化方法,在新疆阿勒泰地区的地质－找矿工作中已取得

与危机矿山接替资源勘查有关的成矿找矿模式

简要叙述了与危机矿山接替资源勘查工作有关的一些成矿找矿模式，包括：绿岩带金矿新模式，斑岩铜矿模式，微细浸染型金矿深部找矿模式，铜镍硫化物深部找矿模式，金和铅锌矿共伴生模式等，以期为危机矿山深部和外围找矿勘查工作提供思路。     

全国主要固体矿产大中型矿山资源潜力调查资料初步汇总概述

中国主要固体矿产大中型矿山大多数分布于中东部地区，对第一批500余座矿山资源潜力调查资料初步评估汇总表明，占矿山总数的3/4矿山为资源型危机矿山，近200座约占1/3的调查矿山具有进一步寻找接替资源潜力；对危机矿山接替资源找矿勘查区的区域分布、主攻矿床类型、找矿预测方法及找矿勘查技术手段等资料数据开展综合汇总，结合相关数理统计分析和GIS空间分析，获得了一批数据图表，为编制“纲要”实施方案和危机矿山专项的工作部署提供了重要依据。     

The concentration and distribution of different mercury species in the water columns and sediment of Aha Lake

In order to find out whether Aha Lake was polluted by the acid mining waste water or not, the concentration and distribution of different mercuryspecies in the water columns and sediment profile collected from Aha Lake were investigated. It was found that discernible seasonal variation of different mercury species in water body were obtained in the Aha Reservoir. With regards to the whole sampling periods, the concentrations of HgP in the Aha Reservoir water body were evidently correlated to the concentrations of total mercury, showing that total mercury was mostly associated with particle mercury. The concentrations of methylmercury in water body were also evidently correlated to the concentrations of dissolved mercury. The dissolved mercury evidently affects the distribution and transportation of methylmercury. However, there is no correlation between methylmercury and total mercury. The dissolved mercury, reactive mercury, dissolved methylmercury levels in the water body of high flow period were much higher than those in low flow period. The distribution, speciation and levels of mercury within the Aha Reservoir water body were governed by several factors, such as the output of river, the release of sediment . Discernible seasonal variation of total mercury and methylmercury in porewater was described during the sampling periods, with the concentrations in high flow period generally higher than those in low flow period. The methylmercury in pore water column was evidently correlated to that of the sediment. The results indicated that highly elevated MeHgD concentrations in the porewater were produced at the depths from 2 to 5 cm in the sediment profile, and decreased sharply with depth. A positive correlation has been found between MeHgD formation and sulfate reducing bacterial activity. These highly elevated concentrations of MeHgD at the intersurface between waters and sediments suggest a favorable methylation condition. Moreover,
