建设中老缅泰国际合作开发区营造景洪市立体开放口岸系统

本文论述了中老缅泰国际合作开发区建设是澜沧江—湄公河流域开发的优先启动区，是南南合作的新模式，对推动中南半岛次区域合作发挥着先导功能。景洪作为中国西南边境城市，在未来次区域合作中将升格为枢纽城市之一，因此，其开放度要不断扩大，在已具有的国家一类水运口岸基础上，要继续营造国家一类航空口岸、公路口岸，并在跨世纪建造昆明—曼谷铁路时，设置国家一类铁路口岸，同时在中缅２４０界桩两侧开辟新型的边境贸易旅游区，构筑景洪市全方位立体型开放系统。

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。     

Structural features and petroleum geology of the fold-thrust belt in the southern Tarim basin, China

The west Kunlun fold-thrust belt (WKFTB) and the Altun fold-thrust belt (AFTB) are respectively located in the southern margin of the Tarim basin, NW China. The analyses of typical structures and regional dynamics of the fold-thrust belts reveal their different structural and petroleum features and mechanisms. WKFTB differs from AFTB by abundant fault-related folds and triangles zones, and was formed by northward extrusion of the west Kunlun orogen. AFTB was affected synchronously by northward extrusion of the Altun orogen and the sinistral strike-slipping of the Altun Fault, so it is characterized by the minor scale and the monotonous structural styles. The Aqike anticline and the Aqike fault, of which the strikes are orthogonal to the strike of the fold-thrust belts, are regarded as the adjustive structures between both of the fold-thrust belts. The oil-gas pools of WKFTB develop mainly in the faulted-related anticline traps, but the oil-gas pools of AFTB develop mainly in the low fault-block and anticlines traps related with the paleo-uplifts. There are different exploration countermeasures for both of the fold-thrust belts.     

Karst database development in Minnesota: design and data assembly

The Karst Feature Database (KFD) of Minnesota is a relational GIS-based Database Management System (DBMS). Previous karst feature datasets used inconsistent attributes to describe karst features in different areas of Minnesota. Existing metadata were modified and standardized to represent a comprehensive metadata for all the karst features in Minnesota. Microsoft Access 2000 and ArcView 3.2 were used to develop this working database. Existing county and sub-county karst feature datasets have been assembled into the KFD, which is capable of visualizing and analyzing the entire data set. By November 17 2002, 11,682 karst features were stored in the KFD of Minnesota. Data tables are stored in a Microsoft Access 2000 DBMS and linked to corresponding ArcView applications. The current KFD of Minnesota has been moved from a Windows NT server to a Windows 2000 Citrix server accessible to researchers and planners through networked interfaces.     

1996-2022年黄河三角洲行水河口岸线稳定性研究

黄河清八汊现行河口自改汊以来发生了巨大变化,监测其岸线变化,探讨其稳定程度对海岸带可持续发展以及海岸带韧性评估具有重要意义。本研究利用GPS、GIS、RS技术从1996—2022年黄河三角洲行水河口的220幅遥感影像中推断出年平均海岸线位置,同时根据行水河口摆动次数划分为5个阶段,并以此为基础对海岸线变迁及其稳定性进行定量分析。结果表明：行水河口岸线长期处于动态变化过程中,整体呈淤进状态,各岸段岸线时空变化特征不同,最大侵蚀（-73.89m/a）区出现在两丁坝之间,最大淤积（393.20m/a）区出现在河口区附近。研究区90%的岸线表现为较强淤积至严重淤积,稳定性指数由两丁坝之间（0.135）、2007年出汊前旧河口（0.068）、2007年出汊后新生河口（0.006）依次降低。入海水沙量、河口位置变迁以及沿岸输沙是影响岸线稳定性出现时空差异的主要原因。
