盐津5.1级地震现场调查与烈度分布

对盐津5．1级地震现场38个居民点、20所学校、8个卫生院（室）及计生站、21项生命线工程及水利工程结构、文化旅游设施和铁路等的震害调查资料进行了分析，得出了本次地震的等烈度分布及有关参数。分析了场地条件、断层、震害异常原因及各类房屋、生命线工程、水利设施等的震害特征和地质灾害特点，并提出了灾区恢复重建的减灾措施和建议。     

三维并行合成震源记录叠前深度偏移

提出了一种基于波动理论的三维合成震源记录叠前深度偏移方法，该方法不含任何物理假设，利用波动方程算子的3个性质，合成炮震源及炮震源记录，将面炮记录合成与相位编码合成两种方法在理论上和计算上合二为一，成为一个统一的合成理论. 通过双重叠加把三维叠前五维数据转换为三维数据，既保证了成像质量同炮记录偏移成像一样精确，又显著地提高了计算效率，且适于复杂地质构造成像. 针对不同情况，给出了几种不同的合成算子，使方法在实际应用中有较大的灵活性和选择性. 基于MPI并行算法的实现，进一步提高了计算效率. SEG＼EAGE盐丘C3_NA数据模型上的试算结果和新疆三维起伏地表实际地震资料的处理结果进一步说明了该方法的有效性和实用性.     

长江口岸带冲淤及后备土地资源的沉降效应——以上海崇明东滩为例

长江口入海泥沙的淤积是上海后备土地资源的重要来源，分析岸带冲淤的演变．有助于对岸带经济圈特别是围垦促淤地区因经济工程活动引发的地面沉降问题的剖析。本文以上海崇明东滩为例，分析30年来的冲淤变化及未来趋势，并据此对新近沉积土的地面沉降效应作简要阐述。     

云南地区房屋建筑的震害矩阵

自1992年4月23日云南孟连西中缅交界6.7、6.9级地震始,地震部门对云南地区的破坏性地震进行了现场灾害调查和经济损失评估。1992~2003年,云南地区共发生50次破坏性地震,积累了丰富的震害资料。本文根据云南地区的主要建筑结构,统计分析了50次地震不同烈度区的破坏比、损失比和震害指数,给出了房屋建筑的震害矩阵。     

渔洞水库地区地震活动性和构造应力场分析

统计了渔洞水库的水位变化规律,分析了水库蓄水前后库区及其附近地区的地震活动性和构造应力场特征。结果表明,水库蓄水前后研究区地震活动的图像、强度和频次都没有明显变化;水库蓄水和水位变化对研究区构造应力场没有明显的影响。     

云南省岩溶水地球物理探测实践

由于岩溶发育的不均匀性,决定了岩溶水的埋藏分布也具有不均匀的特征,含水层富水性的空间差异极大。岩溶水的不均匀性给岩溶水勘查和开发工作带来了很大的困难,以至于裸露型岩溶石山区的供水勘探孔成井率仍然很低。要有效地发挥岩溶水资源的优

Distribution patterns of chlorophyll <Emphasis Type="Italic">a</Emphasis> in spring and autumn in association with hydrological features in the southern Yellow Sea and northern East China Sea

Two field studies were conducted to measure pigments in the Southern Yellow Sea (SYS) and the northern East China Sea (NECS) in April (spring) and September (autumn) to evaluate the distribution pattern of phytoplankton stock (Chl a concentration) and the impact of hydrological features such as water mass, mixing and tidal front on these patterns. The results indicated that the Chl a concentration was 2.43±2.64 (Mean ± SD) mg m^?3 in April (range, 0.35 to 17.02 mg m^?3) and 1.75±3.10 mg m^?3 in September (from 0.07 to 36.54 mg m^?3) in 2003. Additionally, four areas with higher Chl a concentrations were observed in the surface water in April, while two were observed in September, and these areas were located within or near the point at which different water masses converged (temperature front area). The distribution pattern of Chl a was generally consistent between onshore and offshore stations at different depths in April and September. Specifically, higher Chl a concentrations were observed along the coastal line in September, which consisted of a mixing area and a tidal front area, although the distributional pattern of Chl a concentrations varied along transects in April. The maximum Chl a concentration at each station was observed in the surface and subsurface layer (0–10 m) for onshore stations and the thermocline layer (10–30 m) for offshore stations in September, while the greatest concentrations were generally observed in surface and subsurface water (0–10 m) in April. The formation of the Chl a distributional pattern in the SYS and NECS and its relationship with possible influencing factors is also discussed. Although physical forces had a close relationship with Chl a distribution, more data are required to clearly and comprehensively elucidate the spatial pattern dynamics of Chl a in the SYS and NECS.
