| Geological disasters are one of the natural disasters that have a huge impact on human beings on a global scale.China is one of the countries with the largest and deepest impact of geological disasters in the world,with the characteristics of wide coverage,complex disaster mechanism,large destructive power,deep impact and frequent occurrence.Zhushan County is located in the northwest of Hubei Province,at the intersection of the Yangtze Huai Terrace and the Qinling Fold System,with frequent stratigraphic activity.A large number of geological disasters occur every year,mainly landslides,mudslides and collapses,which seriously threaten the lives and property of local residents.At the same time,the blind and disorderly development of mountain villages and towns in recent years not only endangers the natural environment,but also increases the potential hidden dangers of geological disasters,bringing huge risks and adverse consequences to local residents.Therefore,based on the results of geological disaster risk assessment,guiding the spatial planning and construction of villages and towns to ensure their safe and orderly development is a key measure to promote the healthy and sustainable development of mountain villages and towns.This paper takes Zhushan County,Shiyan City,Hubei Province as the research area,and aims to explore the spatial layout of the construction of mountainous villages and towns in the county based on geological hazard risk evaluation.Firstly,the author provides a solid policy and information basis for the study from the policy background and geohazard-related studies.Secondly,through a preliminary understanding of the natural and human geographic environment of Zhushan County,a large amount of basic information was collected by combining the characteristics of past geological disaster occurrences.A variety of qualitative and quantitative methods were used to evaluate and compare the vulnerability of geological hazards in Zhushan County and to compare the optimal solutions.Also,the fuzzy comprehensive evaluation method was used to evaluate and study the vulnerability of geological hazards.Then,based on the results of susceptibility and vulnerability evaluation,the risk evaluation results and zoning of geological hazards in Zhushan County are synthesized.Finally,based on the risk evaluation results,strategies related to the spatial layout of village and town construction in Zhushan County are proposed.The aim is to reduce the threat of geological hazards to the people and promote the smooth development of the new round of territorial spatial planning in Zhushan County villages and towns,so as to guarantee the safe,orderly and healthy development of its village construction space. |
