1.Characteristic parameters and data of field investigation on the impact of disaster chain on major line engineering structures

On the basis of field scientific research, this parameter set integrates the parameters of debris flow disaster chain and landslide disaster chain observed along important roads in Himalayan and Hengduan Mountains. The regional scope covers Nyingchi, Shannan, Bomi, Basu, Shigatse, Ali and other regions of the Tibet Autonomous Region, as well as the East Asia rift valley of the China India channel. The source and mode of data production are processed according to the original data obtained from field scientific investigation. This parameter set is mainly based on the field investigation to determine the location and type of disaster and disaster chain, the damage of major highway projects and other information, and then sorted into tables and shp files. It is hoped that this data can provide help for disaster prevention and reduction of road projects in the Qinghai Tibet Plateau.

2.Types and distribution of 1:250000 major projects in Qinghai Tibet Plateau (1900-2021)

The types and distribution data sets of major projects in the Qinghai Tibet Plateau mainly include major hydropower projects, major road projects, major mining projects, major port projects and oil field projects. Among them, road projects include national highway, high-speed, railway and power grid projects, and hydropower projects are mainly the project point documents of hydropower station dam site. The data is obtained through data collection and remote sensing image interpretation. The main attributes of the project data are project naming (naming method is project type - project name - project construction year, in which the naming method of hydropower project is project type - watershed name - project name - Project storage year), project construction year, related projects and other characteristics. The data has been checked and modified for many times, and the quality is reliable.
