资源勘查图件计算机辅助编绘系统的结构分析与开发策略研究   总被引：7，自引：1，他引：7  

刘刚  汪新庆等 《地质与勘探》2002,38(4):60-63

如何站在信息系统的高度来进行资源图件计算机辅助编绘系统的快速开发，是资源信息系统领域计算机应用的一个重要研究课题。在结构分析的基础上，将资源图件计算机辅助编绘系统划分为图形数据库，应用图形系统和基础图形系统3个基本部分。对于复杂资源图件的计算机辅助编绘，需要地矿点源信息系统的支持。在基础图形系统上进行专业编绘程序的二次开发是高效建立图件编绘系统的最佳途径，并需注意GIS集成应用，三维可视化，人工智能和参数化设计等方法的运用，而系统平台开发是复杂应用的高级阶段。该思想可应用于煤及油气勘探，工程开发，矿区管理及区域地质等诸多领域的软件开发中。  相似文献   

Study on effects of damping in laminated rubber bearings on seismic responses for a ⅛ scale isolated test structure     

Bong Yoo  Yang‐Hann Kim 《地震工程与结构动力学》2002,31(10):1777-1792

The effects of damping in various laminated rubber bearings (LRB) on the seismic response of a ?‐scale isolated test structure are investigated by shaking table tests and seismic response analyses. A series of shaking table tests of the structure were performed for a fixed base design and for a base isolation design. Two different types of LRB were used: natural rubber bearings (NRB) and lead rubber bearings (LLRB). Three different designs for the LLRB were tested; each design had a different diameter of lead plug, and thus, different damping values. Artificial time histories of peak ground acceleration 0.4g were used in both the tests and the analyses. In both shaking table tests and analyses, as expected, the acceleration responses of the seismically isolated test structure were considerably reduced. However, the shear displacement at the isolators was increased. To reduce the shear displacement in the isolators, the diameter of the lead plug in the LLRB had to be enlarged to increase isolator damping by more than 24%. This caused the isolator stiffness to increase, and resulted in amplifying the floor acceleration response spectra of the isolated test structure in the higher frequency ranges with a monotonic reduction of isolator shear displacement.

Implications of the relationship between catchment vegetation type and the variability of annual runoff   总被引：1，自引：0，他引：1  

Murray C. Peel  Thomas A. McMahon  Brian L. Finlayson  Fred G. R. Watson 《水文研究》2002,16(15):2995-3002

The impact of changing catchment vegetation type on mean annual runoff has been known for some time, however, the impact on the variability of annual runoff has been established only recently. Differences in annual actual evapotranspiration between vegetation types and the potential effect of changing vegetation type on mean annual runoff and the variability of annual runoff are briefly reviewed. The magnitude of any change in the variability of annual runoff owing to a change in catchment vegetation type is related to the pre‐ and post‐change vegetation types and the seasonality of precipitation, assuming that the variability of annual precipitation remains constant throughout. Significant implications of the relationship between vegetation type and the variability of annual runoff are presented and discussed for water resource management, stream ecology and fluvial geomorphology.

Agricultural land use in the coastal area of the Alexander von Humboldt National Park, Cuba and its implication for conservation and sustainability     

A. Wezel  S. Bender 《GeoJournal》2002,57(4):241-249

In the Alexander von Humboldt National Park in eastern Cuba many endemic animals and plants are found in various different natural habitats, which are considered to be the most important ones for in-situ conservation in the entire Insular Caribbean. In some areas of the National Park agriculture is practised. Thus, the objective of this study was to document and analyse the different land use activities and their consequences for local resource management and conservation of biodiversity in two village areas. A particular question was: what has changed since the foundation of the National Park in 1996? As time series data for land use and aerial photographs were not available for this part of Cuba, a qualitative evaluation was carried out. For this, six different land use units were mapped in 2001 and additional information gathered for areas with special interest related to sustainable land use and resource conservation. Although most parts of the study area are influenced to various degrees by human impact, the different types of land use seem presently not to have a crucial or detrimental impact on the land resources of the Alexander von Humboldt National Park. However, exploitation of the natural resources in certain areas could be improved with different management options to reach sustainability as well as to meet the conservation objectives of the National Park. This includes reduced or abandoned agricultural use of steep slopes to reduce erosion risk as well as a facilitated regeneration of natural vegetation in many parts of the study area to be able to conserve the high valuable biodiversity of the Park. Environmental education seems to have played an important and successful role since the foundation of the Park in 1996. Since then, cropping on steep slopes as well as illegal logging and poaching could be reduced.  相似文献

鲁中南岩溶区是中国北方半干旱温带岩溶区中具有代表性的地区之一。该区岩水资源分布具有明显的不均匀性和大面积分散补给而局部富集等特征。岩溶形态以溶蚀裂隙洞穴为主，地下水类型多为裂隙溶洞型。在对该区岩溶水补给，富集，径流及排泄特征的研究基础上，初步将本区地表水和地下水资源划分为两大类型，即地下岩溶水径带变化带水资源类型和排泄带水资源及地下岩溶水资源类型。对该地区地表水和地下水的合理调蓄问题进行了系统的分析和总结，并提出了相关的对策。  相似文献
