三维建模在资源量估算中的应用——以安徽桐城枫香岭矿区建筑用片麻岩（机制砂）矿资源量估算为例

随着计算机信息技术与三维图形技术的快速发展,将三维地质建模技术及三维可视化技术运用于资源量估算,可以更加直观地反映矿体的空间形态。本文以安徽桐城枫香岭矿区建筑用片麻岩（机制砂）矿资源量估算为例,详细介绍了运用三维建模技术采用网格法对矿石资源量进行估算的步骤。此应用方法可以为今后三维建模技术运用于资源量估算提供借鉴。     

紧跟技术的时尚潮流——记广西测绘资料档案馆副馆长梅树红

想到档案馆,总想到堆得高高的档案,与历史有关,与灰尘有关. 得知要采访广西测绘资料档案馆副馆长梅树红的时候,脑子里大概勾勒了这样一个女性学者形象:戴着眼镜、和蔼且沉默少语,在堆积如山的资料中深埋着头.出乎意料的是,第一眼梅树红就颠覆了大家的想象:她年轻又时尚,有着一双美丽的大眼睛,很健谈,活跃而又逻辑性很强的思维让我们的采访很顺利地展开了.     

Methods Comparison for Microsatellite Marker Development： Different Isolation Methods, Different Yield Efficiency

Microsatellite markers have become one kind of the most important molecular tools used in various researches. A large number of microsatellite markers are required for the whole genome survey in the fields of molecular ecology, quantitative genetics and genomics. Therefore, it is extremely necessary to select several versatile, low-cost, efficient and time- and labor-saving methods to develop a large panel of microsatellite markers. In this study, we used Zhikong scallop (Chlamys farreri) as the target species to compare the efficiency of the five methods derived from three strategies for microsatellite marker development. The results showed that the strategy of constructing small insert genomic DNA library resulted in poor efficiency, while the microsatellite-enriched strategy highly improved the isolation efficiency. Although the mining public database strategy is time- and cost-saving, it is difficult to obtain a large number of microsatellite markers, mainly due to the limited sequence data of non-model species deposited in public databases. Based on the results in this study, we recommend two methods, microsatellite-enriched library construction method and FIASCO-colony hybridization method, for large-scale microsatellite marker development. Both methods were derived from the mi-crosatellite-enriched strategy. The experimental results obtained from Zhikong scallop also provide the reference for microsatellite marker development in other species with large genomes.     

Study of Panjin Wetlands Along Bohai Coast(Ⅱ):Ecological Water Requirement of Shuangtaizi Estuarine Wetland

Shuangtaizi estuarine wetland along the Bohai Sea coast,the biggest bulrush wetland in the world,has been listed in ‘The Record of Important International Wetland Conservation District’. Taking the year of 2 000 as an example,the minimum,the most suitable and the maximum ecological water requirement of Shuangtaizi estuarine wetland are calculated in this paper based on both ecological theory and Geological Information System technology. In addition,the remote sensing technique is adopted in the data acquisi...

Historical development in soil micromorphological imaging

The book ＂micropedolog＂ by Kubieana and a large number of publications has induced many people to practice soil micromorphology. Quantification of the soil fabric and its components was a major challenge. The use of the image analyses in soil science was a breakthrough. Attempts to make soil thin sections go back to the beginning of the 2oth century. Microscopic techniques and recently high resolution electron microscope and use of computer assisted imaging techniques enabled the in vitro study of soils in three dimensional levels. It is now possible to store and process massive amounts of data. Micro- morphological concepts and techniques are applied in paleopedological, ecological, and archaeological studies. The aim of this work was to examine soil micromorphological imaging in historical perspective.
