By analyzing and explaining the source ,meaing and usage of the word “Mound”,this article discussed the cultural relations between the word “Mound” and Chinese traditional settlement on the face of form origin ,Feng Shui idea,living patterns and symbolic meaning.
本文通过对“丘”字的字源、字义和用法的解释分析,探讨了丘字与中国传统聚落在形成渊源、风水观念、聚居方式及象征意义等方面的文化关联,说明汉字所表达的概念与其所表达的客观事实有着高度的一致性,这不仅是古人的智慧,也是我们解读中国传统建筑文化的有效方法。

在实地调查和多年定位研究的基础上,根据目前沙漠化过程研究的需要,介绍了沙地、沙丘、沙漠化土地等相关概念及其主要区别,阐述了沙地、沙丘、沙漠化土地类型的划分标准以及类型互换使用中应该注意的问题;通过分析影响沙漠化发展方向和过程的关键因素,建立了沙漠化正、逆发展过程的地面判别指标体系,并讨论了不同类型沙丘的主要来源、发展方向及转换过程的判别方法。

In seismic exploration, subsurface salt dome, as a high-velocity geologic body, brought about a series of problems to ordinary processing in time domain and interpretation, for example, false image of subsalt structure and abnormal stack velocity field.
在地震勘探中,地下盐丘作为一个高速地质体会给常规时间域处理和解释带来一系列的问题,如盐下构造的假象和叠加速度场异常等。
The Lower Permian of uplifts in east merging of littoral Caspian Sea basin is a set of giant thickness of salt beds and multiple salt domes with significant thickness developed locally, in which the thickness is from 200m to 3500m.
滨里海盆地东缘隆起带下二叠统是一套巨厚的膏盐层,局部发育多个巨厚盐丘,厚度从200～3500m不等。
There are massive salt domes of great thickness,which ranges from several dozen meters to 3,700 meters,in pre-salt Carboniferous carbonate reservoirs of the Pre-Caspian Basin.
由于盐丘和围岩间存在巨大的速度差异,因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变(如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象),消除盐层的影响是含盐油气盆地勘探的重要课题。
It is pointed out that upward pinchout sandstone bodies along valleys and hammocks close to faults are favorable f.
