摘要:
为查明四川省甘孜藏族自治州地质灾害的发育特征及成灾机理，中国地质调查局成都地质调查中心于2010年在四川省甘孜州雅江县开展了以县域为单元的1：5万地质灾害详细调查项目。项目以遥感、地面调查、测绘、勘查为主要工作手段，查明了该区域内地质灾害及其隐患的发育特征、分布规律及形成的地质环境条件。为了更好地利用这些数据，采用了规范的数据处理方法和质量控制体系，对调查的地质灾害数据进行整理和质量控制，该调查数据集提供了2010年雅江县行政范围内的327组地质灾害数据，调查精度达到1：5万级别，有效地反映了区内地质灾害的发育特征与分布规律，可为该区域内工程地质研究、减灾防灾和制定区域防灾规划提供基础地质灾害依据。
Abstract:A detailed survey of geological disasters at the scales of 1:50000 in Yajiang city was conducted by Chengdu Center of China Geological Survey in 2010, with the intention of finding out the development characteristics and mechanisms of geological disasters in the Tibetan Autonomous Prefecture of Garze. The characteristics, distribution and geological conditions of the geological disasters in the region were identified by remote sensing, survey, engineering mapping and exploration. In order to further utilise these data, we processed them with standard data processing methods and a quality control system. The survey dataset could provide a geological basis for engineering geological research, disaster prevention and disaster reduction, as well as the development of regional disaster prevention planning.
