GIS支持下青海湖地区草地蝗虫发生的地形分析

草地蝗虫发生的地形分析是建立草地蝗虫发生预报模型的基础，以青海湖地区为实验区，在Arc/Info和ArcView地理信息系统的支持下，进行草地蝗虫发生与各地形变量（包括海拔高度、坡度与坡向）的叠置分析，提取草地蝗虫发生的地形信息数据库，然后，分别采用T－检验（对连续变量－海拔高度和坡度）和卡方（Chisquare)检验（对类变量－坡向类型）进行各地形变量对草地蝗虫发生的差异显著性检验，结果表明，海拔高度和坡度对草地蝗虫发生的影响极为显著（显著性水平p=0.000)，而坡向地草地蝗虫发生的影响不是特别明显（显著性水平p=0.039)。

底质不连续面类型、成因及遗迹学特征

底质不连续面是沉积作用中断时所形成的一种地层界面。根据底质的粘结程度可将底质不连续面划分为两大类：固底不连续面和硬底不连续面。固底不连续面中的简单停积面依靠沉积序列的变化来识别，界面上、下的生物地层带是连续的；而复成停积面上、下的生物地层带不连续。在硬底不连续面中，硬底的上、下地层属于同一个沉积体系，而继承性岩底的上、下地层则属于不同的沉积体系，其间发生过重大的沉积间断。根据底质控制的Glossifungites遗迹相和Trypanites遗迹相可以有效地识别各类不连续面并解释其成因。三种类型的不连续面具有层序地层学意义：①侵蚀性不连续面，包括低水位侵蚀面（LSE）和海进侵蚀面（TSE）；②无沉积间断面；③沉积性不连续面（凝缩段）。     

Dinosaur tracks from the Cretaceous of South Korea: Distribution, occurrences and paleobiological significance

Abstract   Abundant dinosaur fossils including dinosaur footprints, eggs and nests, teeth and bones have been found from the Cretaceous non-marine deposits of Korea. Among them, dinosaur tracks are the most distinctive, and some track sites are among the most famous in the world. Until now, 27 dinosaur track localities have been discovered from the Cretaceous strata in the Gyeongsang Basin and several small basins. Ornithopod tracks are most abundant at most Korean track sites, and most of them are identified as Caririchnium ; that is, large ornithopod footprints with wide hoof impressions. Most theropod tracks are found in Neungju Basin and they consist of various types of small or medium-sized bird-like footprints, and other large footprints. Sauropod tracks are also abundant in the Gyeongsang Basin. The sauropod tracks vary in size, shape, and pattern of trackway, and suggest that diverse sauropods existed in this area. These diverse tracks in South Korea suggest that various dinosaurs flourished at the margins of lakes distributed in the southern part of the Korean Peninsula during the Cretaceous.

Is Prediction of Future Landslides Possible with a GIS?

This contribution explores a strategy for landslide hazard zonation inwhich layers of spatial data are used to represent typical settings inwhich given dynamic types of landslides are likely to occur. Theconcepts of assessment and prediction are defined to focus on therepresentation of future hazardous events and in particular on themyths that often provide obstacles in the application of quantitativemethods. The prediction rate curves for different applications describethe support provided by the different data layers in experiments inwhich the typical setting of hazardous events is approximated bystatistically integrating the spatial information.

龙王嘴边坡系坡高达70 m、坡角达70 °的高陡岩质边坡。分析了宜-秭公路石峡段龙王嘴高边坡变形的地质条件,在定量评价龙王嘴高边坡稳定性的基础上,进行了该高边坡的施工图加固设计。根据其特点将350 m长的坡段分为A,B,C三个区,分别采取预应力锚索与锚杆加固、挂网喷射混凝土支护和喷射混凝土支护等措施,实践证明,工程治理效果良好。     

Validation of Landslide Susceptibility Maps; Examples and Applications from a Case Study in Northern Spain

A procedure for validating landslide susceptibility maps wasapplied in a study area in northern Spain and the results obtained compared. Validationwas used to carry out sensitivity analysis for individual variables and combinationsof variables. The validity of different map-making methods was tested, as well as theutility of different types of Favourability Functions. The results obtained show thatvalidation is essential to determine the predictive value of susceptibility maps. Italso helps to better select the most suitable function and significant variables, thus improving the efficiency of the mapping process. Validation based on a temporal strategy makes it possible to derive hazard maps from susceptibility maps.
