青藏高原1:25万重大工程类型及分布（1900-2021）

青藏高原重大工程类型及分布数据集主要包括重大水电工程、重大道路工程、重大矿山工程、重大口岸工程及油田工程，其中道路工程包括国道、高速、铁路及电网工程，水电工程主要为水电站坝址工程点文件。通过收集资料及遥感影像解译的方式进行数据获取，工程数据的主要属性为工程命名（命名方式为工程类型--工程名称--工程建设年份，其中水电工程命名方式为工程类型--流域名称--工程名称--工程蓄水年份）、工程建设年份、相关工程及其他特征。数据经过多次检查修改，质量可靠。Dataset of Major Engineering Types and Distribution on the Qinghai-Tibet Plateau mainly covers major hydropower projects, major road engineering, major mining engineering, major port projects and oilfield engineering. Among them, road engineering includes national highways, expressways, railways and power grid engineering, while hydropower projects mainly refer to the engineering point files of hydropower station dam sites. Data was acquired through data collection and remote sensing image interpretation. The main attributes of the engineering data include engineering naming (the naming rule is engineering type--engineering name--construction year; for hydropower projects, the naming rule is engineering type--basin name--engineering name--water storage year), construction year, related projects and other characteristics. The data has undergone multiple inspections and revisions, ensuring reliable quality.
