鄂尔多斯盆地苏里格庙气田上古生界盒8段地质与地球物理响应特征

苏里格庙气田主要产气层为上古生界石盒子组盒8段，属于三角洲平原分流河道沉积。复合砂体近南北向展布；单砂体的厚度变化大，非均质性明显，储渗变化大。盒8段含气砂岩在AVO资料上有明显反映；在综合测井资料上，盒8段表现出自然伽玛测井值、密度测井值、补偿中子测井值都偏低，电阻率、声波时差测井值较高，出现了大幅度的自然电位异常。利用核磁共振测井技术测得苏里格庙区某井盒8段3555．9m～3559．6m为气层，3560．6m～3572m为气水层，与生产实践吻合得很好。     

基于共反射点叠加的观测参数选择

在地震勘探数据处理中，通常采用的共中心点(CMP)叠加技术对于复杂的地质构造难以取得好的效果。若通过从道间距、覆盖次数等观测参数与目标层地层倾角、共反射点离散度的关系出发，并结合模型正演，对复杂构造地层的观测参数选取进行优化，使之能对目标层尤其是逆断层下降盘的阴影层段进行较充分的“照明”，即可得到共反射点叠加剖面，这对共反射点叠加是一项有益的研究。     

宁夏中北部地区沙尘暴天气发生过程中的不稳定条件分析

从沙尘暴的形成条件入手，对宁夏中北部地区近30a来沙尘暴天气发生过程中的不稳定条件进行了较为详尽的分析。结果表明：沙尘暴发生三前，大气的不稳定性明显增强；沙尘暴天气发生时不稳定性主要发生在700hPa以下，最为突出的是850hPa以下；沙尘暴发生过程中不稳定性达到最强。     

海岸带临港工业、海运物流与全球化大生产的探讨

海岸带是世界人口密集、经济发达的地带，在全球经济一体化和全球化大生产中具有重要的地位。近半个世纪以来，海岸带临港工业迅速崛起并持续高速发展，依托海港建设、大型船舶运输发展起来的临港工业和海运物流，在跨国公司的运作下形成了现代意义上的全球化大生产。这种生产方式使资源贫乏的日本快速发展成发达国家；深圳赤湾临港工业区成为中国高效益工业的典范。本文着重讨论了海岸带经济建设中大力发展临港工业对地区、国家和全球经济的影响，指出中国21世纪应大力开发利用海岸带港湾资源、重点建设全球化大生产的大进大出的基地，建立若干个具有国际竞争力的海岸带产业中心，推动国民经济持续、快速发展。

A precise monitoring of snow surface height in the region of Lambert Glacier basin-Amery Ice Shelf,East Antarctica

The net surface snow accumulation on the Antarctic ice sheet is determined by a combination of precipitation, sublimation and wind redistribution. We present a one-year record of hourly snow-height measurements at LGB69 (70°50'S, 77°04'E, 1850 m a.s.l.). east side of Lambert Glacier basin (LGB), and 4 year record at G3 (70°53'S, 69°52'E, 84 m a.s.l.), Amery Ice Shelf (AIS). The measurements were made with ultrasonic sensors mounted on automatic weather stations installed at two sites. The snow accumulation at LGB69 is approximately 70 cm. Throughout the winter, between April and September, there was little change in surface snow height (SSH) at the two sites. The negative SSH change is due to densification at LGB69, and is due to both ablation and densification at G3. The strongest accumulation at two sites occurred during the period between October and March (accounting for 101.6% at LGB69), with four episodic increasing events occurring during 2002 for LGB69, and eight events during 1999-2002 for G     

Changes in the spatial scale of Beijing UHI and urban development

The seasonal and interannual variations of Beijing urban heat island (UHI) are investigated in this paper using the temperature data from 1960 to 2000 at 20 meteorological stations in the Beijing region, and then the relationship between the intensity and spatial scale of UHI and Beijing urbanization indices is analyzed and discussed. Main conclusions are the followings. First, Beijing UHI shows obvious seasonal variations, and it is strongest in winter, next in spring and autumn, and least in summer. The seasonal variation of the UHI mainly occurs in the urban area. The UHI intensity at the center of Beijing is more than 0.8℃ in winter, and only 0.5℃ in summer. Second, the intensity of Beijing HUI exhibits a clear interannual warming trend with its mean growth rate (MGR) being 0.3088℃/10 a. The MGR of HUI is largest in winter, next in spring and autumn, and least in summer, and the urban temperature increase makes a major contribution to the growth of HUI intensity. Third, since the Reform and Opening, the urbanization indices have grown several ten times or even one hundred times, the intensity of HUI has increased dramatically, and its spatial scale also expanded distinctively along with the expansion of urban architectural complexes. Fourth, the interannual variation of urbanization indices is very similar with that of HUI intensity, and their linear correlation coefficients are significant at a more than 0.001 confidence level.
