发展矿业 重振地勘经济

进入市场经济,地勘单位要生存和发展,必须充分发挥地勘行业自身优势,走兴办矿业经济之路,应抓住当前的机遇,开发市场紧销矿产品,要用好矿权,采用多种模式,多渠道吸引社会资金,减少投资风险,争取最高效益,同时要十分重视整理和利用积累的地质资料,为兴办矿业提供必要的科学依据。     

Local responses to changed circumstances: Coalmining in the market economy in Upper Silesia, Poland

It is argued that the emphasis of much recent research into coalmining has been placed on international and national scale influences which affect coalfields as a whole; change at the intra-coalfield scale has received less attention. After providing a background to events in Poland during communism, attention focuses on developments since 1989, commencing with coalfield-wide influences. There follows an examination of the work of the state body Państwowa Agencja Węgla Kamiennego, which executes government policy at the local level, and whose membership is drawn from the coalfield region. This agency recommends the closure and amalgamation of mines, but otherwise rationalisation measures are left to the seven mining companies and the colliery managers. The restructuring which has been carried out is considered under five heads: organisational change within the collieries, employment, production and technical change, and ecological adjustment. While recognising the importance of the socioeconomic and political environment and geology, there is much evidence to suggest that intra-coalfield patterns are strongly determined by local decision-makers.

地震活动因子A值及其在华北地震中短期预报中的应用

综合考虑了地震活动时空强３ 个方面的震兆特征,定义了地震活动因子 Ａ值．使用１９７２ ～１９９６ 年华北地区地震资料进行空间扫描,研究中强以上地震前 Ａ 值的中短期异常变化特征．结果表明,在中短期阶段大多数地震前出现的 Ａ 值中期异常区面积明显缩小或消失,也有一些地震前１ ～３ 个月 Ａ 值异常区面积再次增大．还就用 Ａ 值进行地震中短期预报的有关问题进行了讨论     

商业建筑的昨天今天和明天

从人们交换农业、手工业产品的“市”到店铺林立的商业一条街,商业和商业建筑的发展与社会和经济的发展密不可分,现代商业建筑的发展更与人们生活和消费水平分不开。因此,必须研究人们的职业与消费习惯、消费心理、做好市场调查和预测,把握市场机遇,创造适合经济和社会发展各阶段的商业间环境,研究国外现代商业建筑的发展,借鉴其经验,使我国商业建筑沿着正确的道路发展。     

新疆皮山地区地震动衰减关系研究

利用2015年7月3日皮山M_S6.5地震序列的波形资料,采用微遗传算法反演得到震源区的5个介质参数,即应力降Δσ为75.95bars,品质因子Q_0为186.33,η值为0.26,几何衰减分段点R_1为72.18km,R_2为139.70km;并由此计算得到的傅氏谱再配合随机相位谱,进而得到地震动时程,建立了震源区地震动衰减关系。由于缺乏强震记录,本文还收集了2008年10月5日乌恰M_S6.9地震、2008年10月6日阿克陶M_S6.2地震、2012年3月9日洛浦M_S6.0地震的强震数据,将计算结果与经验性衰减关系以及3次强震记录进行比较后发现,皮山地震、洛浦地震的强震数据普遍高于经验性衰减关系,乌恰地震的强震数据与俞言祥等文中的衰减关系吻合较好,在远场低于本文的计算结果。     

Main active faults and seismic activity along the Yangtze River Economic Belt: Based on remote sensing geological survey

The Yangtze River Economic Belt (YREB) spans three terrain steps in China and features diverse topography that is characterized by significant differences in geological structure and present-day crustal deformation. Active faults and seismic activity are important geological factors for the planning and development of the YREB. In this paper, the spatial distribution and activity of 165 active faults that exist along the YREB have been compiled from previous findings, using both remote-sensing data and geological survey results. The crustal stability of seven particularly noteworthy typical active fault zones and their potential effects on the crustal stability of the urban agglomerations are analyzed. The main active fault zones in the western YREB, together with the neighboring regional active faults, make up an arc fault block region comprising primarily of Sichuan-Yunnan and a “Sichuan-Yunnan arc rotational-shear active tectonic system” strong deformation region that features rotation, shear and extensional deformation. The active faults in the central-eastern YREB, with seven NE-NNE and seven NW-NWW active faults (the “7-longitudinal, 7-horizontal” pattern), macroscopically make up a “chessboard tectonic system” medium-weak deformation region in the geomechanical tectonic system. They are also the main geological constraints for the crustal stability of the YREB.

Climatological Characteristics of the East Asian Winter Monsoon Simulated by CWRF Regional Climate Model

Based on the ERA-Interim atmospheric reanalysis data from the European Medium-Term Weather Forecast Center from 1979 to 2016 and the ERSSTv4 sea surface temperature data from the US National Oceanic and Atmospheric Administration, the regional climate model CWRF was used to simulate the climate characteristics in East Asia. The results show that the CWRF model can well reproduce the average characteristics of the East Asian winter monsoon circulation, including the location and intensity of the low-level continental cold high pressure and variation characteristics of wind field in high and low levels. The occurrence area and frequency of the north wind in the simulation and the reanalysis data were further calculated and compared. It is shown that they are basically consistent. The distribution of air temperature and precipitation over China are well represented by the model. The water vapor transport is also in good agreement with the reanalysis data. The water vapor from the Bay of Bengal plays a vital role in the precipitation over South China. The simulation results of apparent heat source and apparent moisture sink show that the model can well simulate the thermal difference between the East Asian continent and the adjacent sea area. The analysis results indicate that CWRF model has the ability to simulate the main characteristics of the East Asian winter monsoon.     

Geographical Conditions and National Strategies

This paper is a summary based on the relationship between national conditions and development strategies for decades of consulting research. Through cases, the paper outlined the basic meaning of national conditions and geographical conditions and their close relationship with national development strategies, and emphasized the importance of comprehensive thinking and scientific judgment in the process of carrying out the governments’ strategies and development policies, and making development policies. At last, suggestions were made that the points of China’s national conditions and the rules of connection with government decision-making should be written into geography textbooks as well as into textbooks for party schools of the Communist Party of China.
