“5.12”震后区域地质灾害危险性评价研究——以青川、平武县为例
|
摘要
四川省"5.12"地震影响区,诱发了大量滑坡、崩塌、泥石流等地质灾害,给人民生命财产造成了重大损失。震后要相当长的余震期,加之降雨大,地质灾害还有进一步恶化的趋势。运用地面调查方法很难满足要求,尤其是很难满足时效性,结合研究区地质背景特征和多源遥感数据解译结果,确定地质灾害评价的指标体系,综合运用数学方法、GIS技术,对平武、青川县进行了地质灾害分布规律分析及危险性评价,提高了数据处理的时效性。其研究成果对灾区风险评估、灾后重建,尤其是高山峡谷地震多发区的防灾减灾研究具有借鉴意义。
A large number of landslides,collapse,mudslides and other geological disasters were induced in the "5.12" earthquake affected zone in Sichuan province,which make people′s lives and property cause the heavy losses.After the earthquake,there is a long period of aftershocks,combined with a large rainfall,so geological disasters will further deteriorate.With ground survey method it is difficult to meet the requirements,especially difficult to meet timeliness.With combined results of multiple source of remote sensing data interpretation,and determining the geological hazard assessment index system and distribution analysis and geological hazards assessment on Qingchuan and Pingwu county by mathematical method and GIS technology,it is possible to improve the timeliness of data processing.The research on disaster risk assessments and post-disaster reconstruction,especially in mountain valleys in earthquake-prone areas of disaster prevention and mitigation,possesses the reference.
