医学地质遗迹概念和评价体系的建立

在分析和研究医学地质学和地质遗迹发展现状的基础上,首次提出了医学地质遗迹的概念,并对其进行了厘定.我国医学地质遗迹主要分布在"东北地区-太行山-黄土高原-武陵山-四川盆地-云贵高原"一线,地形特征复杂,大型断裂构造带集中.依据致病元素将医学地质遗迹分为5类:硒缺乏(克山病、大骨节病)医学地质遗迹、硒中毒医学地质遗迹、碘缺乏(地方性甲状腺肿)医学地质遗迹、氟中毒医学地质遗迹和地球化学元素致癌医学地质遗迹.以自然地质属性和科研价值为主要评价因子,建立了医学地质遗迹评价体系,并以湖北恩施硒中毒地质遗迹为实例进行评价,结果表明该评价体系具有实用性和可操作性.

The establishment of the concept and assessment system of medical geoheritage

Based on an analysis and study of the development of medical geology and geoheritage, the authors put forward for the first time the concept of medical geoheritage. Medical geoheritages in China are mainly distributed along the zone from Northeast China through Taihang Mountain, Loess plateau, Wuling Mountain and Sichuan basin to Yunnan-Guizhou plateau, with complex topographic characteristics and fault tectonic belts. Medical geoheritages can be classified into five types on the basis of pathogenic elements, namely, selenium deficiency (Keshan disease, Kaschin-beck disease), selenosis, iodine deficiency disorders (endemic goiter), endemic fluorosis and carcinogenic geochemical elements. With natural geological attributes and scientific values as the main evaluation factors, the authors built the assessment system of medical geoheritage. The assessment of the selenosis medical geoheritage in Enshi indicates that this assessment system is practicable and operable.
