Human Settlements Risk Assessment From The Perspective Of Geology Geochemistry Environment In Kangding County

Human living environment is the space closely associated with human living activities, which is not only the basis for human in nature but also the main room for human beings to make use of nature and remake nature. Urban geological geochemical environment is the important space for human living and the important basis for city development, thus an important content in human Settlements Risk Assessment study.This thesis builds the risk evaluation system in both theories and methods for city's human Settlements from the perspective of urban geology geochemistry, thus making a useful probe in the harmony between urban geological environment and human Settlements.Urban human Settlements risk studies focus on the uncertain damaging factors of city geological environment on human beings from the perspective of city geochemistry, which is actually the study of the correlation between the social nature and the natural nature of city geological environment. The higher the correlation is, the higher the appropriateness, and the less the risks.The risk assessment system for urban human living environment put forward in this thesis plays a model role for other cities, which consists of three ratings of evaluation reports. The first rating report contains the divisional risk factors evaluation result, which mainly serves the city government. The second rating report contains the geological background, the geological hazards' risks, and the geochemical frangibility, which mainly serves the city's planning-making agencies. The third rating report contains the essential evaluation factors about the divisional risk evaluation for the urban environmental geology, which mainly serves the city administration and construction departments.Urban human Settlements risks include three parts, namely the geological background, the geological hazards' risks, and the geochemical frangibility. Kangding County has complicated geological conditions and thus relatively more geological hazards, and the risk evaluation theory has its function here.The geological background evaluation in Kangding County is the foundation of the human Settlements risk evaluation system, which focuses on not only the evaluation theory system, but...
