This data is the disturbance disaster data of 1:250000 major projects in the Qinghai Tibet Plateau. For the scope of disaster interpretation, line engineering (national highway, high-speed, railway and Power Grid Engineering) and hydropower engineering are bounded by the first watershed on both sides of the project; Mine, oilfield and port projects are bounded by 1km away from the project. Engineering disturbance disasters can be divided into two categories: ① landslide, collapse and debris flow disasters induced by engineering construction; ② For natural disasters that may affect the project, it is stipulated that all natural disasters within the above interpretation scope belong to category ② engineering disturbance disasters. The data includes the location, length, width, height difference, distribution elevation, genetic type, inducing factors, occurrence time, lithology and other elements of landslide, disaster related projects and project construction years. Based on Google Earth image and 1:500000 geological diagram, 6176 disaster points were interpreted; Google Earth is mainly used for disturbance disaster interpretation, and combined with field investigation to verify the interpretation results, ArcGIS is used to generate disaster distribution map; The data comes from Google Earth high-resolution images, with high accuracy of original data. In the process of generating disaster files, the interpretation specifications are strictly followed, and special personnel are assigned to review, so the data quality is reliable; Based on the collected data, the disaster risk analysis of the study area can be carried out to provide theoretical guidance for the smooth operation of the built projects and the construction of the line projects not built / under construction.

File naming and required software

Disaster naming:
Disaster types: h for landslide, B for collapse, l for debris flow, t for ground collapse, f for ground fissure, C for land subsidence, etc.
Projects: hydropower, highway, railway, mine, port, etc.
1、 Hydropower project: sd-js-bht-hx2011001
SD stands for hydropower project, JS stands for Jinsha River, BHT stands for the initial capital of hydropower station reservoir area, HX stands for new landslide (HL stands for old landslide, if the old landslide is resurrected, it is represented by HX), 2011 is represented by the age of landslide, 001 is the first disaster point of the project, sorted by serial number, regardless of year.
2、 Highway Engineering: GL - g318-hx2011001
GL stands for highway engineering, G318 is the name of the highway, and HX stands for new landslide (HL stands for old landslide, for example, the resurrection of old landslide is represented by HX).
3、 Railway Engineering: tl-cz-hx2011001
TL represents Railway Engineering, CZ represents Sichuan Tibet railway, and HX represents new landslide (HL represents old landslide, for example, the resurrection of old landslide is represented by HX).
4、 Mine engineering: ks-jc-hx2011001
KS represents mine engineering, JC represents Jinchuan nickel mine, and HX represents new landslide (HL represents old landslide, for example, the resurrection of old landslide is represented by HX).
5、 Port project: ka-zm-hx2011001
Ka refers to the port project, ZM refers to Zhangmu port, and HX represents the new landslide (HL represents the old landslide, for example, the resurrection of the old landslide is represented by HX).
6、 Power Grid Engineering: dw-zz-hx2011001
DW represents the power grid project, ZZ represents the Tibet China networking, HX represents the new landslide (HL represents the old landslide, for example, the resurrection of the old landslide is represented by HX). Data reading method: all shp files in the dataset can be opened with ArcGIS software, and the layer contains attribute information such as naming and related projects.
