青岛市近50年来的旱涝分析

利用一旱涝指标来分析青岛市近50年来的旱涝情况。结果表明，青岛市近50年来，重旱年份为1994，1995年，重涝年份为1956，1964年，而春、夏、秋、冬四季为重旱或重涝的年份基本都不相同；青岛市近50年来，总的早涝趋势是越来越旱的，而总的来说1973年以前是涝的，1973年以后是旱的；近50年来，青岛市的春、夏、秋、冬四季的干旱增强趋势的程度是不同的，秋季的干旱增强趋势的程度是不同的，秋季的干旱增强趋势最明显，而夏季的干旱增强趋势最不明显。     

南沙西南地区新构造运动及其动力学机制

本文根据南沙西南地区的岩石圈动力学环境，把本区新构造运动类型划分为拉张型，挤压型，平移剪切型和旋动型，并对其构造演化阶段和动力学机制进行了初步分析。

浙西地区“扬子型”铅锌矿床的找矿潜力初探

“扬子型”铅锌矿床的地质特征 一、矿化集中的时空分布 “扬子型”铅锌矿床在准地台周边及其隆起的碳酸盐中分布很广,成矿时期从南华纪至早古生代,最重要的有南华系莲沱组（彭山式）,震旦系陡山沱组上部（董家河式）,震旦一寒武系麦地坪组（大渡河式）,下寒武系清虚洞组（花垣式）。除此,在奥陶系、石炭系和三叠系也有发现。这类矿床形成于晋宁造山后扬子地台伸展裂陷构造环境,是罗迪尼亚超大陆裂解事件的产物。空间上主要分布以下地区：

GIS在处置地下管线突发事件中的应用研究——以苏州市地下综合管网应急处置系统为例

随着经济社会的不断发展,城市建设步伐不断加快。近几年,各类地下管线突发事件频发。通过"苏州市地下综合管网应急处置系统"项目的开发和实践,本文试图从总体上论述地下综合管网突发事件的处置过程、应用原理及相关的技术实现,重点阐述了基于"12345"便民服务中心工作平台,在充分利用GIS的网络分析技术的基础上,实现城市地下管网突发事件应急处置的自动化和信息化。     

Guadalupian （Middle Permian） Conodont Faunas at Shangsi Section, Northeast Sichuan Province

This study recovered the Guadalupian conodont faunas from Shangsi (上寺) Section in Northeast Sichuan (四川). Four genera and nine species were identified, and three conodont zones were recognized and established; they include Jinogondolella nankingensis Zone, J. aserrata Zone, and J. postserrata Zone. The Roadian and Wordian boundary is set in the interval 5 m from the top of Bed 86 by the first appearance of the conodont J. aserrata. The Wordian and Capitanian boundary is set in the interval 2.3 m from the top of the Bed 95 by the first appearance of J. postserrata. Most of the specimens demonstrated low color alteration index (CAI) as 1.5-3, indicating that most part of the Maokou (茅口) Formation may have the suitable thermal conditions for the formation of oil source rocks.     

Mechanism of Secondary Pore Formation and Prediction of Favorable Reservoir of Paleogene in Jiyang Sag,Eastern China

Jiyang (济阳) sag is an oil rich basin,consisting of Huimin (惠民),Dongying (东营),Zhanhua (沾化),and Chezhen (车镇) depressions.The elastic rock of Paleogene has undergone early and middle diagenetic stages and now the main clastic reservoir is in the middle diagenetic stage.Primary and secondary pores are developed in Paleogene sandstone,the latter is generated from the dissolution of feldspar and calcite cement in rocks owing to the organic acid from the maturated source rock,but the materials dissolved are different in different depressions.The reservoir secondary pores of Dongying depression are generated from the dissolution of calcite cement,the ones of Zhanhua and Huimin depressions from the dissolution of feldspar,the secondary pores of Chezhen depression from the dissolution of feldspar in upper section,and the dissolution of calcite cement in the lower section of Paleogene,respectively.The secondary pores are developed in two depths and the depth goes down from west to east,from south to north in Jiyang sag.The major controlling factors for secondary pore development are maturity and location of source rock.Lastly,the favorable reservoirs are evaluated according to reservoir buried depth,sedimentation,and diagenesis.The reservoir with high quality is located in the northern and central parts in Dongying depression; there are some good reservoirs in Gndao (孤岛),Gudong (孤东),and Gunan (孤南) areas in Zhanhua depression,and the favorable reservoirs are located in the north steep slope and the south gentle slope of Chezhen depression and central uplift,south gentle slope of Huimin depression.
