【摘要】：贺兰山岩画在世界岩画中占有重要的地位,由于自然环境因素的长期作用,贺兰山岩画遭受到了严重的破坏,若不尽快采取有效措施,这些珍贵的历史文物将不复存在。但是,截至目前关于贺兰山岩画风化机理的研究甚少,从而严重制约了对其风化机理准确地、有效地科学认识。为此,以贺兰口岩画为研究对象,在风化现状调查的基础上,对其保存环境的温度、湿度、大风及沙尘天气等数据进行统计分析,利用X射线衍射仪、扫描电子显微镜等测试手段,并结合冻融实验和风洞试验进行风化病害机理研究。研究发现,贺兰口岩画以长石杂砂岩为主,引起其风化的因素有温度、湿度、风沙等。其中,温度变化和风沙剥蚀为主要病害因素。该研究有望为全面了解岩画风化机理以及其后续保护工作的实施提供理论基础。
[Abstract]:Rock paintings of Helan Mountain play an important role in the world rock paintings. Due to the long-term effect of natural environment, rock paintings of Helan Mountain have been seriously damaged. If effective measures are not taken as soon as possible, these precious historical relics will no longer exist.However, up to now, there are few researches on weathering mechanism of rock paintings in Helan Mountain, which seriously restricts the scientific understanding of weathering mechanism accurately and effectively.Therefore, taking Helankou rock painting as the research object, based on the investigation of weathering status, the data of temperature, humidity, gale and dust weather of its preservation environment were analyzed statistically, and the X-ray diffractometer was used.The mechanism of weathering disease was studied by scanning electron microscope (SEM) combined with freeze-thaw test and wind tunnel test.It is found that feldspar complex sandstone is the main rock painting in Helankou, and the weathering factors are temperature, humidity, sand and so on.Among them, temperature change and wind erosion are the main disease factors.This study is expected to provide a theoretical basis for the comprehensive understanding of weathering mechanism of rock painting and the implementation of its subsequent protection work.
