青藏高原地质构造数据库

本数据包含国内青藏高原范围内的1:400万精度的断裂数据，属性表字段包括断裂名称、断裂长度、走向、倾向、断层性质、古地震等。该数据来源于地震局，后来通过大量查阅断裂相关的文献，又在原始数据的基础上添加了断裂的活动年代这一属性。原始数据资料精度可靠，并有专人负责质量审查；经多人复查审核，其数据完整性、位置精度、属性精度均符合有关技术规定和标准的要求，质量优良可靠。该断裂数据可为青藏高原区域的一些断裂相关的研究工作提供基础数据支撑。

This dataset contains 1:4,000,000-scale fault data within the Qinghai-Tibet Plateau of China. The attribute table includes fields such as fault name, fault length, strike, dip, fault nature, paleoearthquake, and others. This dataset was originally sourced from the Seismological Bureau, and subsequently, the attribute of fault activity age was added to the original data based on extensive reviews of literature related to faults. The original raw data had reliable accuracy, with dedicated personnel responsible for quality review. Following multiple rounds of rechecking and verification, the data's completeness, positional accuracy, and attribute accuracy all meet the requirements of relevant technical regulations and standards, with excellent and reliable overall quality. This fault dataset can provide fundamental data support for various fault-related research studies in the Qinghai-Tibet Plateau region.
