At the heart of the cultural approach in geography: Thinking space

The way that space is thought of is at the heart of the cultural approach in geography. The passing down of all the components of a culture depends upon the way data is aquired and processed, the results memorized or broadcast. Communication shapes the experience and the knowledge of space and time. It gives to everyone the idea that the real world is doubled by a beyond which plays a central role in social life, since it is upon such a beyond that normative thinking relies and that a significance is given to individual and social life. The spheres of lived-in and known space and time, as well as that of the beyond, vary according to available technologies.

High-Altitude CUSP: The Extremely Dynamic Region in Geospace

The high-altitude dayside cusps (both northern and southern) are extremely dynamic regions in geospace. Large diamagnetic cavities with significant fluctuations of the local magnetic field strength have been observed there. These cusp diamagnetic cavities are always there day after day and are as large as 6 R_E Associated with these cavities are charged particles with energies from 20 keV up to 10 MeV. The intensities of the cusp energetic ions have been observed to increase by as much as four orders of the magnitude when compared with regions adjacent to the cusp which includes the magnetosheath. Their seed populations are a mixture of ionospheric and solar wind particles. The measured energetic ion fluxes in the high-altitude cusp are higher than that in both the regions upstream and downstream from the bow shock. Turbulent electric fields with an amplitude of about 10 mV/m are also present in the cusp, and a cusp resonant acceleration mechanism is suggested. The observations indicate that the dayside high-altitude cusp is a key region for transferring the solar wind mass, momentum, and energy into the Earth’s magnetosphere.     

GIS中矢量与栅格数据模型比较

由于GIS软件的多样性，每种软件都有自己特定的数据模型，从数据结构上来说，矢量和栅格是地理信息系统中两种主要的空间数据结构。本文通过对栅格数据与矢量数据模型的应用比较．对于空间数据从需求分析，以满足对数据信息进行更改、更新、增加或者为了某种特定的需要。

基于遥感反演的山东半岛东北部海域悬浮体时空变化规律探讨

基于2003—2018年中分辨率成像光谱仪(moderate-resolution imaging spectroradiometer,MODIS)卫星遥感影像资料,结合2018年春季、夏季和冬季大面站悬浮体取样分析结果,构建了表层悬浮体浓度遥感反演模型;在此基础上,分析了山东半岛东北部海域年际和月份表层悬浮体浓度时空分布规律,探讨了表层悬浮体浓度变化的主控因素和水体结构季节变化及其对悬浮体分布输运的影响。结果表明:山东半岛东北部海域表层悬浮体总体呈近岸高远岸低的分布特征,东部成山头区域悬浮体浓度较高且向海扩散较远,西部威海湾及外侧海域悬浮体浓度较低且扩散范围小于东部。研究区悬浮体浓度季节性变化显著但对应季节年度变化较小,冬季悬浮体浓度达到最大,春秋季次之,夏季最低。研究区春季、秋季和冬季表层悬浮体浓度主要受控于北向风浪和潮流,而夏季悬浮体浓度主要受潮流控制。夏季,温跃层阻碍了悬浮体垂向扩散,导致表层悬浮体浓度极低;冬季,研究区东部成山头附近水平分布的弱温跃层虽然会在一定程度上抑制悬浮体的再悬浮,但再悬浮扩散仍是造成研究区高悬浮体浓度的主要因素。山东半岛东北部存在类似"夏储冬输"的特征...
