宗教文化旅游对游客的影响研究 ——以武当山道教文化旅游为例

以武当山为研究案例地,通过游客问卷与访谈调查,采用SPSS18.0统计软件定量分析武当山旅游体验对游客认知、思想、行为意愿等的影响。研究结果表明,① 武当山游客的旅游动机有宗教朝圣、文化体验、娱乐放松及感情交流4类;② 宗教文化旅游影响游客对目的地的形象感知及对道教文化的认知、态度及践行意愿;③ 宗教文化旅游对游客的影响强弱因动机而不同,自强至弱依次为宗教朝圣、文化体验、感情交流及娱乐放松。

永登系列爆破甘宁青地区地震台网的观测解释与地壳结构

1982—1983年在甘肃永登地区进行了系列人工大爆破,本文分析研究了甘宁青地震台网的观测记录,求得各种波的平均速度为:V_(?)=6.00公里/秒,V_(?)=3.56公里/秒,V_(pn)=8.16公里/秒,V_(?)=4.54公里/秒。表层直达纵波速度V_o=4.82公里/秒。莫霍界面上的反射波P_M在140—180公里范围比P_g波强10—7倍。並获得该地区的地壳厚度为:(1)甘肃北山的河西堡—高台一带为48.3公里。古浪—张掖—嘉峪关的河西走廊一带为50.2公里。祁连山南麓为53.6公里。(2)青海中南部为54.4公里。(3)甘肃东部的礼县—武都地压为48.7公里。定西—岷县—通谓地区为50.5公里。(4)宁夏六盘山区为51.6公里。六盘山西侧的甘肃静宁为48.6公里,东侧的平凉为47.5公里,东南端的陕西宝鸡为46.1公里。以上的地壳厚度分布显示了青藏高原地壳在东北边缘的递减,以及甘肃东部地区地壳的某些起伏。     

临涣矿区水化学特征及在矿井水源判别中的意义

通过分析、比较临涣矿区三个地下水子系统的水文地球化学特征得出，这三个子系统在水溶标型发及少、微量元素的含量上无明显差别，表明各子系统间存在水力联系，而环境同位素氘和＾１８Ｏ分析则是解决矿井水来源判别的有效方法。     

地震数据采集器中△-∑AD转换器512kHz数据流的仿真

根据△-∑AD转换器原理，通过编程将给定的输入信号转换为1位串行△-∑数据流。用此数据流可以仿真地震数据采集器中的滤波抽样过程，检验设计构造的各级滤波参数能否满足地震观测的需要。为了证明该仿真程序的正确性，本文介绍了利用CS5376A公布的数字滤波参数对数据流进行滤波验证。     

Heavy metal pollution in sediments of a typical mariculture zone in South China

The heavy metal inventory and the ecological risk of the estuarine sediments in Hailing Bay, an important maricultural zone along the southern coast of China, were investigated. Results show that the surface sediments were mainly polluted by As (2.17-20.34 mg/kg), Ni (1.37-42.50mg/kg), Cu (1.21-58.84 mg/kg) and Zn (11.69-219.22 mg/kg). Furthermore, the aquafarming zone was significantly more polluted than the non-aquafarming zone, and cluster analysis suggested additional sources of heavy metal input in the aquafarming zone. As, Cr, Cu, Ni, Pb and Zn were mainly present in the non-bioavailable residual form in the surface sediments, whereas Cd was predominantly in the highly mobile acid soluble and reducible fractions. The ecological risk of the polluted sediments stemmed mainly from Cd, and from As, Cu and Pb to less degrees. The highest potential risks occurred near the aquaculture base, indicating the need to control heavy metal inputs from aquafarming activities.     

闽江河口地区河道演变及其影响因素分析

比之传统的调查方法,利用遥惑技术进行岸线解译具有范围大、多时段、省时、省力以及快速等优点。根据多时相TM遥惑数据,对闽江河口地区岸线进行解译,结合20世纪60年代地形图和2001年海图,分析了河口地区河道演变情况．对河流岸线和浅滩变化进行对比分析,发现闽江口南部水道多呈淤积状态,北边水道则为弱侵蚀型岸线;南部水下浅滩有新发育,原有的浅滩面积有很大的扩展,北边水道变化较小;文章最后对河道演变的影响因素进行了初步的探讨。     

BRINGING FORWARD OF THE CONCEPT OF COGIS AND ITS ARCHITECUTRE RESEARCH

Based on the analysis of the development of GIS technology and application,this paper brought forward the concept of GoGIS,namely Cooperative GIS ,CoGIS is GIS facing group-users and supporting human-human interaction,which makes it differ from the former GISs,Then,the characteristics of general Computer Spport Cooperative Work (CSCW)applications and the complexity of Geographic Information Science were analyzed,and the conclusion the CoGIS was not a simple GIS layer on CSCW was reached,Further,this paper gaver the hierarchical architecture of CoGIS,and analyzed the coperative platform in detail from the following:1)basic elements;2) collaboration patterns;3) cooperation control mechanism;4) synchronization mechanism;5) security and 6) group communication and so on.With those,the problems about GIS applications are discussed,such as 1)distributed multi-source GIS information and knowledge sharing platform;2)the fusion and visualization of GIS information;3)virtual reality cooperative modeling;4) dymamic simulation;5)expert system and 6) decision-making.Finally,this paper analyzed CoGIS application mode in brief.     

鄂尔多斯盆地东胜富氦气田成藏特征及其大地构造背景*

近年来,在鄂尔多斯盆地北缘东胜气田上古生界天然气中发现伴生的氦气,含量分布在0.045%~0.487%范围内,具有工业价值,其三级储量约为8.3亿立方米,为一特大型含氦—富氦天然气田。东胜气田氦气属于典型的壳源氦,来源于基底的太古界—元古界变质岩—花岗岩系,富集与燕山期以来的岩浆侵入、断裂活动有关。东胜气田具备有利的氦气成藏地质条件,伴生氦气与烃类气具有异源同储成藏特征,剖析其成藏主控因素为: 基底富U、Th岩石发育是基础,断裂活动是核心,储盖圈保条件是必备,时空配置是关键,其中早白垩世是最重要的一期构造—岩浆热事件,深源岩浆活动导致的深部物质和热能的大规模上涌是中生代流体成藏(矿)的有利地球动力学背景,控制了鄂尔多斯盆地石炭系—二叠系煤系烃源岩大规模生气。断裂活动和圈闭形成与上古生界天然气、氦气聚集成藏具有良好的时空配置关系,与华北克拉通破坏过程耦合。鄂尔多斯地块在早白垩世至中新世深部热流体对盆地发生的多期岩浆活动、基底断裂活化及浅部断裂活动具有明显的控制作用,同时也对石炭系—二叠系煤系烃源岩成烃成藏具有重要的控制作用。
