无锡、常州郊区发生地裂缝

无锡、常州郊区发生地裂缝近年来，无锡石塘湾西蔡一秦村～带、常州横林分别出现了地裂缝，其中以钱桥毛村园最为严重，该处地裂缝于１９９１年夏初步形成，随后不断扩大，目前已具一定规模，长约７００ｍ，总体宽约６０ｍ，呈近东西向分布，并造成附近数十间楼房产生大量...

中国南方海相含油气保存单元的层次划分与综合评价

以最近十年中国南方的海相新区油气勘探评价成果为依托 ,以油气成藏和整体封闭保存体系评价为核心 ,在渝东—湘鄂西、中下扬子和滇黔桂三大区域划分出 9个有利区块 5 1个含油气保存单元 ,并将其归纳为四个层次。综合评价认为 ,方西和石柱保存单元具有较好的整体封存体系 ,属持续性含油气保存单元 ,为首选勘探目标 ;江汉盆地南部、句容—海安区块、南鄱阳坳陷、楚雄盆地东北部具备或基本具备整体封存条件 ,属于沉积重建型含油气保存单元 ,通过精细勘探可望获得商业性油气流 ;楚雄盆地西北部、南盘江坳陷、十万大山盆地和渝东—湘鄂西地区利川复向斜由于晚期强烈构造改造而仅存在部分封存体系 ,需要攻关探索 ;思茅、渝东—湘鄂西地区的花果坪和桑植—石门地区已失去整体封闭保存条件 ,仅局部存在封存体系 ,地质条件高度复杂 ,勘探风险甚高。     

Simulation Experiments of Land Surface Physical Processes and Ecological Effect over Different Underlying Surface

Based on the existing Land Surface Physical Process Models(Deardorff, Dickinson, LIU, Noilhan, Seller, ZHAO), a Comprehensive Land Surface Physical Process Model (CLSPPM) is developed by considering the different physical processes of the earth‘s surface-vegetation-atmosphere system more completely. Compared with SiB and BATS, which are famous for their detailed parameterizations of physical variables, this simplified model is more convenient and saves much more computation time. Though simple, the feas...     

基于GIS的攀西地区铂族元素成矿地质条件初步分析

攀西地区以良好的铂族元素(PGE)成矿地质背景，而成为我国铂族元素找矿热点地区之一。本文在建立攀西地区铂族元素矿床地质概念模型的基础上，用地理信息系统(GIS)分析了该地区的铂族元素成矿地质条件，包括地质构造、峨眉山玄武岩、基性一超基性岩和铂族元素地球化学异常特征。指出研究区的深大断裂对铂族元素的富集表现出很好的控制作用，峨眉山玄武岩为铂族元素的矿源层之一，岩浆岩为铂族元素的富集提供了成矿物质及成矿能量。     

The GIS and analysis of earthquake damage distribution of the 1303 Hongtong M=8 earthquake

The geography information system of the 1303 Hongton M=8 earthquake has been established. Using the spatial analysis function of GIS, the spatial distribution characteristics of damage and isoseismal of the earthquake are studies. By comparing with the standard earthquake intensity attenuation relationship, the abnormal damage distribution of the earthquake is found, so the relationship of the abnormal distribution with tectonics, site condition and basin are analyzed. In this paper, the influence on the ground motion generated by earthquake source and the underground structures near source also are studied. The influence on seismic zonation, anti-earthquake design, earthquake prediction and earthquake emergency responding produced by the abnormal density distribution are discussed. Foundation item: National important fundamental research “The Basic Research of Important Project in Damage Environment” and The important project “The Seismic Hazard Assessment Research and Anti-earthquake Structure Research” from China Earthquake Administration during the 10th Five-year Plan.

农业地质信息在农业地质研究与区划中的应用

农业地质是以地质理论为基础与大农业专业理论相结合以解决农业相关问题，服务于农业，以在农业生产实践中获取最大的社会和经济效益。虽然我国正在广泛开展农业地质调查获取了较多的农业地质信息，但信息利用程度低，发挥的经济效益不够理想。分析了在我国开展农业地质研究的意义及其存在的问题，并就农业地质信息在农业区划中的应用进行了探讨。     

A time-space based approach for mapping rainfall-induced shallow landslide hazard

A rainfall-induced shallow landslide is a major hazard in mountainous terrain, but a time-space based approach is still an unsettled issue for mapping rainfall-induced shallow landslide hazards. Rain induces a rise of the groundwater level and an increase in pore water pressure that results in slope failures. In this study, an integrated infinite slope analysis model has been developed to evaluate the influence of infiltration on surficial stability of slopes by the limit equilibrium method. Based on this new integrated infinite slope analysis model, a time-space based approach has been implemented to map the distributed landslide hazard in a GIS (Geographic Information Systems) and to evaluate the shallow slope failure induced by a particular rainfall event that accounts for the rainfall intensity and duration. The case study results in a comprehensive time-space landslide hazard map that illustrates the change of the safety factor and the depth of the wetting front over time.
