Abstract


At present, China will shift to the west entral focus of economic development. China strives to build a beautiful grand northwest. However, endemic diseases are still a serious threat to the local population to health. The endemic disease is a restriction of the economic and social development of negative factors. For example, the Kashin-Beck disease manifestations are foot and squat, mobility and other anomalies. Sichuan plateau area is a serious area of Kashin-Beck disease, how to effectively address the endemic, is now one of the issues to be resolved. The subject of study for rich endemic areas of research, solve practical problems, have important theoretical research and practical significance.The Rouergai country areas is now one of Kashin-Beck disease affected areas, the paper features the region’s geological environment in topography, lithology, soil, drinking water and diet and other factors were analyzed. The typical ward and light conducted a geological survey of non-endemic area and sampling, etc. The paper study has measured rock, soil, drinking water, food, human hair and other element composition in samples, and based on the research, geological Characteristics from topography, lithology, soil, drinking water and diet, and the F content of trace elements such as life and the relationship between the distribution of Kashin-Beck disease, and for the plateau area of prevention and treatment of Kashin-Beck disease and provide scientific basis for geological. The study has the main conclusions of this paper proceeds as follows:1. The research situation of landform and have corresponding relation, live in topography deep cut area residents living in the gentle than the high prealence of residents.2.The lithological weathering intensity and rigidity of diseased conditions have certain effect, rock weathering degree of weak area than weathering rates low.3. In the Ruoergai area drinking water the fluorine content majority of villages are lower than national the average level (1mg/L), in Ruoergai Kaschin-Beck disease in serious illness area drinking water the F content is in low or the extremely low level (F≤0.25mg/L), has the comparison significance difference with the non-minor illness area.4. The study on water element in the components of the comprehensive analysis shows that the results show that:the incidence and research are F is remarkable linear relationship.5.The light of the soil, human hair ward, food samples of most serious content component elements in the area in elements.6.Match reasonably along with living standards’ enhancement and the local resident diet structure’s diversification and food, no matter in minor illness area or serious illness area, is sick the situation to have the obvious declining trend.
