项国土资源部“金土工程”正式立

由国土资源部向国家申报的“金土工程”一期建设项目建议书，于5月31日得到国家发改委正式批准。“金土工程”成为2002年确定的国家“十二金”电子政务重点工程之外第一个正式批准立项的电子政务工程项目。按照国家发改委对项目建议书的批复，“金土工程”一期建设包括：制定相关国土资源信息化标准；在国土资源部、31个省（市、区)和32个城市，建立相关土地基础数据库和耕地保护业务管理应用系统：建立重要矿产的矿产资源基础数据库和管理应用系统；     

谈矿产资源储量核查检测在矿政管理工作中的作用

国务院要求国土资源部作为宏观经济管理部门要把工作重点深化到矿产资源战略研究和总体布署上来，要放到为国家提供资源保障上，放到对矿产资源开发实行严格的监督管理上，坚持两个方针，坚持对土地和矿产资源实行最严格的管理制度。中国的国民经济在实现第二战略目标时用了20年，国民经济翻了两番，资源储量翻一番，就是说通过资源供应保证我国经济发展翻两番这一成果。从另一角度来说，国民经济产值所消耗的资源在世界上站前列，这种粗放式利用资源来增加国民生产总值代价是非常高的。资源不可再生，如何利用和保护好资源成为摆在矿政管理者面前的重要课题。     

Sequences in the Hardness Ratio-Peak Energy Plane of Gamma-Ray Bursts

The narrowness of the distribution of the peak energy of the vFv spectrum of gamma-ray bursts (GRBs) and the unification of GRB populations are great puzzles yet to be solved. We investigate the two puzzles based on the global spectral behaviors of different GRB populations, the long GRBs, the short GRBs, and the X-ray flashes (XRFs), in the HR - Ep plane (HR the spectral hardness ratio) with BATSE and HETE-2 observations. It is found that the long GRBs and the XRFs observed by HETE-2 seem to follow the same sequence in the HR-Ep plane, with the XRFs at the low end of this sequence. We fit the sequence by a universal Band function, and find that this sequence is mainly defined by the low energy index α, and is insensitive to the high energy index,β. With fixed β=-5, a best fit is given by α=-1.00 with X^2min/dof=2.2. The long and short GRBs observed by BATSE follow significantly different sequences in the HR-Ep plane, with most of the short GRBs having a larger hardness ratio than the long GRBs at a given Ep. For the long GRBs a best-fit yields α=-0.30 and β=-2.05. For the short GRBs, a best fit gives α=-0.60 with x^2min=1.1 (withβfixed at-2.0 because it is numerically unstable). The α value for the short GRBs is significantly greater than that for the long GRBs. These results indicate that the global spectral behaviors of the long GRB sample and the XRF sample are similar, while that of the short GRBs is different. The short GRBs seem to be a unique subclass of GRBs, and they are not the higher energy extension of the long GRBs.     

浚县矿产资源补偿费征收提前超半

今年以来，浚县国土资源局创新矿产资源补偿费征管措施，取得明显成效。至4月底，矿产资源补偿费征收额同比去年增长17．5％，提前两个月完成全年任务的51％，创历史新高。     

广西河池地区矿产资源勘查成果展销会情况介绍

１９９５年７月１１日—１２日，广西地矿厅和河池地区行署首次联合举办矿产资源勘查成果展销会，会址设在河池市，与会代表１３０余人。展销会提交大会展销的矿产资源勘查成果３８项，引资勘查项目３８项。经买卖双方三天的洽谈，涉及到的项目２５项，会议期间签订矿产资源勘查成果合同协议４项，愈千万元，取得较好的社会经济效益。为地勘资金多渠道来源开辟了新路子，对促进地勘单位地质找矿工作及勘查成果有偿使用发挥了重要作用
