西部省会城市新型城镇化水平综合测度研究

新型城镇化是中国经济社会健康、稳定、可持续发展的根本途径，也是消除中国城乡社会经 济“二元结构”的根本出路。根据新型城镇化的内涵，从人口、经济发展、生活质量、基础设施、资源 环境、城乡统筹 6 个方面，构建了包含 24 项指标的新型城镇化水平综合测度指标体系，运用熵值 法，对西部 11 个省会城市 2005—2015 年的城镇化发展水平进行综合测度。研究表明：西部省会城 市的新型城镇化发展水平存在显著差异，总体上可分为“高等水平”、“中等水平”、“低等水平”3 个 级别，基础设施建设是造成差异的主要驱动力。各城市不同年间的城镇化单项水平影响因素呈现 多元化，在今后的发展中应有所侧重，同时兼顾城镇化质量，推动城乡协调发展。     

济宁市嘉祥县石灰岩矿山地质环境评价与治理

在对嘉祥县石灰岩矿进行地质灾害危险性评估、矿山环境地质问题评价的基础上,建立了一套评价体系,其中地质灾害危险性评估分为2个评价指标,矿山环境地质问题评价分为2种要素3个指标,同时将矿山恢复治理难易程度也作为一个评价因子。评价过程中对各指标危害性大、中、小程度均单独赋值,然后将各指标的分值进行叠加,确定出矿山环境地质问题的等级,将概划出的13个评价单元分为极差、差、一般3个区。提出了强化矿山管理、植树造林、科学避让、修建拦水坝等保护与治理措施及建议。

全球Ms≥7￣3／4级地震的定向迁移

对全球尺度的６条大地震带内１９００～１９９０年中１８４次Ｍｓ≥７３／４级地震进行了沿地震带方向定向迁移的分析，获得了全球统一的地震定向迁移规律，总体是由西向东，迁移速度由７００ｋｍ／ａ变为１５０ｋｍ／ａ，此现象可以作多种暂态地球动力作用过程的推论，如以大西洋脊间歇式张裂引起上地幔软流物质自西向东运动，呈现纵波式的振荡传播；也可解释为非洲板块、阿拉伯板块和印度板块自西南向东北对欧亚地震带依次的推压引起向东的应变波的传播；太平洋脊两侧洋底板块向西北和东北两侧的斜向推压，可能是造成两侧地震带地震向北迁移的触发源     

Interpretation of transient electromagnetic soundings over three-dimensional structures for the central-loop configuration

Summary. An assessment is made of the bias of fitting constrained layered-earth models to transient electromagnetic data obtained over 3-D structures. In this assessment we use the central-loop configuration and show that accurate estimates of the depth of burial of 3-D structures can be obtained with layered-earth model fitting. However, layered-earth interpretations are not reliable for estimating depth extents and resistivities of 3-D structures. When layered earths are used for interpretation, it is advantageous in some cases to use data based on the magnetic field instead of the voltage. A magnetic-field definition of apparent resistivity, in contrast to a definition based on the voltage, eliminates apparent-resistivity overshoots and undershoots in the data. A resistivity undershoot in the data can produce an extraneous and misleading layer in an interpretation of a 3-D resistive structure. Due to 3-D effects, apparent-resistivity soundings (magnetic field and voltage) may rise so steeply at late times that it may not be possible to fit a sounding to a reasonable layered-earth model. Truncating such a sounding, over a buried conductor, allows for a reasonable layered-earth fit and an accurate estimate of the depth to the conductor. However, the resistivity of the conductor is overestimated.
Measurements of the horizontal field in the central-loop configuration can map 3-D structures, provided the sensor is located accurately at the centre of the transmitting loop. Horizontal-field calculations show that the transients peak on the flanks of a 3-D structure, but are depressed over the structure's centre. Weak transient responses flanked by two large transient responses, which are opposite in sign, locate the structure. The sign reversal is caused by a corresponding reversal in the currents that are channelled through or deflected away from conductive or resistive structures, respectively.     

FUZZY COMPREHENSIVE EVALUATION OF CONTAINER TRANSPORTATION MODES ALONG THE CHANGJIANG RIVER MAIN LINE AND ITS DELTA AREA

The Changjiang River (Yangtze) is one of the fastest growth areas of container transportation in Chi-na. Rail, road and water transportation have competed against each other for container transportation in the Chang-jiang River main line and its delta area. It is of significance to assess these different transportation modes scientifi-cally in order to organize container transportation efficiently in this area and make decision for integral plan and construction of transportation system in this area. This paper outlines application of fuzzy comprehensive evaluation to appraise different modes of typical direction of containers. Twelve assessment indexes were decided. Membership functions were formulated. Evaluation results indicated that road transportation was optimal mode in the Changjiang River delta area, however water transportation was the primary way in the Changjiang River main line.     

伊通盆地梁家地区奢岭组混源扇三角洲内幕结构

伊通盆地梁家地区(二号断层上盘)钻井揭示奢岭组是该区主要的油气富集层,目前研究结果认为奢岭组储集层是由两个方向的扇三角洲混合沉积形成,但由于资料有限,应用常规方法无法清楚地认识两个不同方向的物源混合沉积的扇三角洲的内幕特征以及这两个物源如何动态地控制着砂体的分布,影响了对该区油气储集层的深入认识.应用地震和地质资料,在波阻抗反演结果二次解释的基础,解析了这两个混合物源扇三角洲的内幕特征和演化特征,得出3个结论:(1)伊通盆地梁家地区奢岭组至少有4期扇三角洲沉积,每期扇三角洲的沉积范围由下向上逐渐扩大,反映了基准面逐渐下降的过程;(2)奢岭组的4期扇三角洲是由两个物源混合沉积形成,这4期扇三角洲逐渐由受从二号断层来的物源控制为主,变为由受从北东方向来的物源控制为主;(3)基于波阻抗体进行的砂层组解释和分析,能够清楚地分析扇三角洲沉积体的内幕结构,是应用波阻抗进行高分辨率地震分析和应用的一种新的分析方法.     

贵州修文小山坝铝土矿中镓等伴生元素分布规律研究

通过ICP-MS等分析方法对贵州小山坝铝土矿中伴生元素的研究,发现该矿床TiO2、Ga、Ge、Sc、Nb、Li和REE等有用伴生元素在铝土矿矿体中均有较高富集,其含量大多接近或超过了工业综合利用标准,具有较大的经济价值,特别是矿区富铁铝土矿石中Ga和Sc等含量异常高.贵州铝土矿资源丰富,其伴生元素在铝土矿冶炼过程中所产生的赤泥中更为富集,因此,贵州铝土矿综合利用前景十分巨大,这些元素潜在的经济价值,在某种程度上,甚至会超过主导产品氧化铝的价值.开展铝土矿中镓等伴生有用元素的分布及赋存状态的研究,对于镓等稀散元素在特殊地质地球化学环境中超常富集机制、矿产资源综合价值的重新认识评估和矿产资源的综合利用将十分重要,不仅可为铝工业注入新的活力,增加新的经济增长点,而且还可以解决大量赤泥堆放和利用问题,同时获得较大的社会效益与环境效益.
