对山东测绘工作的一些思考

测绘是我国进行现代化建设的先行性工作，测绘成果是国家重要的基础性、战略性资源，事关国家安全和民族利益，地理空间信息资源已成为经济社会信息化的公共基础平台。近年来，山东的测绘事业有了很大的发展，但与省委、省政府的要求相比，与国家测绘局领导同志的期望相比，与山东其他行业飞速发展的形势相比，山东的测绘工作任重道远，需要以新的精神状态、新的观念和新的工作方式，加倍工作，努力为山东的经济社会发展提供优质服务和强有力的测绘保证。     

Characteristics of horizontal crustal move-ment in Weihe basin and adjacent zones by GPS observation

Introduction GPS observation results provide high-accuracy and large-range crustal movement data with real time, which makes it possible to obtain the velocity field of current crustal movement in Chi-nese mainland within a short time and check the previous tectonic deformation model. Geoscien-tists at home and abroad have made a great number of researches on the crustal movement in Chi-nese mainland and have obtained many results in this field (JIANG, et al, 2001; WANG, et al, 2001; ZHA…     

腾冲火山区的形变特征

利用现有的腾冲火山区水平及垂直形变资料进行分析研究,结果表明,水平形变网覆盖的２０００ｋｍ＾２区域内,大部表现为面收缩的趋势。马鞍山、来凤山、腾冲县城一带,地表基本保持平稳,并以此为界,其北面大部上升,而南部下降。由此谱明火山区内地下岩浆仍在运动。     

西秦岭北缘断裂带东段断层泥的粒度分布和显微构造特征

根据采集的天然断层泥样品，对西秦岭北缘活动断裂带东段的断层泥首次进行了粒度分布和显微构造特征的实验研究。研究结果表明，该断裂带以粘滑运动为主，兼有蠕滑活动，并具张性扭动特征。     

利用SAR图像监测海上石油污染的实验分析

本文讨论了利用ＳＡＲ 图像监测海上石油污染的理论依据和环境条件,并根据ＲＡＤＡＲＳＡＴ 卫星装载的合成孔径雷达（ＳＡＲ）图像对渤海ＣＢ－６Ａ 井组发生的原油（气）泄漏事件进行了初步的研究和分析。     

对台湾强震的预警时间研究

The paper collects the records by the Fujian Digital Seismic Network of 40 shallow earthquakes in Taiwan with M_S≥5.0 from 1999 to 2013,analyzes the seismic phase(Pn,Sn phase)characteristics and travel-time rules,determines travel-time models and develops a seismic phase travel-time equation based on the two-step fitting algorithm.With the deduction of processing time and network delay time,this method can provide an accurate estimation of early warning time of Taiwan earthquakes for the Fujian region,and has been officially employed in the earthquake early warning system of Fujian Province.     

松辽盆地徐家围子断陷安达次洼火山岩气藏的主要特征

徐家围子断陷是由徐西、徐中和徐东3条断裂控制的复式箕状断陷,安达次洼位于该断陷北部,火山岩岩性复杂,储层发育受控于多种因素.综合地震、地质、钻井、测井、岩心、测试及岩屑、气-水的物理化学资料,对该区营城组火山岩气藏的构造、储层和成藏特征进行了系统的研究.火山岩气藏的流体分布总体上遵循重力分异原则,以上气下水为主,说明构造位置对含气性具有一定的控制作用.火山岩相带展布、各井的试气成果及测井资料表明：本区营城组气藏没有统一的气-水界面,区内预测火山岩地层连续分布,储层错叠分布,横向连通性差,含气范围覆盖全区,气藏主要受岩性和岩相控制,为构造-岩性气藏.     

树木年轮资料的可靠性分析——以陕西华山松为例

依据陕西华山的华山松树木年轮宽度、最大密度与最小密度年表，以及对树木生长模拟结果，本文分析了树木径向生长对气候因子（气温和降水）的响应状况。结果表明树木年轮生长的多种指标均能相互印证，并具有生理学意义，从而证实了它们作为气候变化的代用资料是可靠的。这不仅强调了树木年轮多途径分析的必要性，而且为重建过去气候变化提供了依据。     

Doppler Radar Data Assimilation with a Local SVD-En3DVar Method

An observation localization scheme is introduced into an ensemble-based three-dimensional variational (3DVar) assimilation method based on the singular value decomposition technique (SVD-En3DVar) to improve assimilation skill. A point-by-point analysis technique is adopted in which the weight of each observation decreases with increasing distance between the analysis point and the observation point. A set of numerical experiments, in which simulated Doppler radar data are assimilated into the Weather Research and Forecasting (WRF) model, is designed to test the scheme. The results are compared with those obtained using the original global and local patch schemes in SVD-En3DVar, neither of which includes this type of observation localization. The observation localization scheme not only eliminates spurious analysis increments in areas of missing data, but also avoids the discontinuous analysis fields that arise from the local patch scheme. The new scheme provides better analysis fields and a more reasonable short-range rainfall forecast than the original schemes. Additional forecast experiments that assimilate real data from 10 radars indicate that the short-term precipitation forecast skill can be improved by assimilating radar data and the observation localization scheme provides a better forecast than the other two schemes.
