齐鲁文化中山东古代书院与文化名人时空特征研究

齐鲁文化是培育新时期山东精神的丰富文化资源,也是新时期山东精神的深厚文化基础.齐鲁书院曾经是一个重要的教育机构.齐鲁书院与文化名人生平轨迹体现了古代文化、学术变迁的轨迹和趋势,大大促进了当今齐鲁文化的传承和发扬.如今已有的少量对书院和文化名人的研究多为人文研究,对齐鲁地区书院与人文的时空分布研究同样较少.本文通过收集历史人文数据和自然地理数据,利用分布中心分析、缓冲区分析、空间统计分析、栅格运算分析和空间插值分析等GIS方法对齐鲁古代书院和文化名人的时空特征进行了深入探究,结果表明,书院建设受当时自然、政治、经济的影响较大;孔子、孟子等文化名人在各大书院的活动更是为当时齐鲁文化的发展做出了重要贡献;书院不仅是人才的集中地,更是当时的人才培养基地,其空间分布也为当时人才选拔奠定了基础.本文中的时空分析对于了解古代齐鲁书院的发展、教育史,汲取良好教化资源和发扬地域文化,协同推近中国梦的实现具有重要的现实意义.     

Seasonal variations in sulfur isotopic composition of dissolved SO<Subscript>4</Subscript><Superscript>2−</Superscript> in the Aha Lake,Guiyang and their implications

The Aha Lake is a seasonal anoxic water system in the southwest of Guiyang City, Guizhou Province, China. Seasonal variations in SO42- concentrations and their isotopic compositions in lake water as well as in the tributaries were investigated in this study. The results showed that sulfate concentrations in river water range from 0.94 to 6.52 mmol/L and their δ34S values range from -14.9‰ and 0.9‰, while lake water has sulfate concentrations ranging from 1.91 to 2.79 mmol/L, and δ34S values from -9.8‰ to -5.9‰. It is suggested that coal mining drainage is the major source of SO42- in the Aha Lake. Rainfall, sewage discharge, sulfide oxidation and gypsum dissolution have made only limited contributions. Different depth-dependent distributions of dissolved SO42- and δ34S were de-veloped for both DB and LJK in summer and winter. Due to water overturn, δ34S values display homogenous vertical distributions in winter and spring. While in summer and autumn, significant positive shifts of δ34S were clearly ob-served in epilimnion and bottom strata as a result of water stratification. High δ34S values in epilimnion may result from the retention of rainwater during water stratification. Dissimilatory sulfate reduction by bacteria was thought to be responsible for the increase of δ34S value in hypolimnion.

Civilian monitoring video records for earthquake intensity: a potentially unbiased online information source of macro-seismology

We collected and analyzed 68 civilian monitoring videos recording the scenes of the May 12, 2008, Wenchuan earthquake. These video recordings are shared online by volunteers after the earthquake. Intensity was estimated by visual inspection of the playback video recordings. Comparing to traditional media accounts, these video records have the distinctive unbiased feature in obtaining local intensity due to their dynamic and repeatable nature. We argue that with proper guidance for providing the necessary information of the location and time when sharing these data online, civilian monitoring videos are potentially more and more useful in the citizen-powered macro-seismology.     

Interactive generalization on large-scale topographical map supported by a database platform

This paper makes a study on the interactive digital generalization, where map generalization can be divided into intellective reasoning procedure and operational procedure, which are done by human and computer, respectively. And an interactive map generalization environment for large scale topographic map is then designed and realized. This research focuses on: ¹ the significance of researching an interactive map generalization environment, ² the features of large scale topographic map and interactive map generalization, ³ the construction of map generalization-oriented database platform.
