藏东南帕隆藏布流域冲积扇地貌形态数据集
A dataset of alluvial fan morphometry in the Parlung Tsangpo Basin,southeast Tibet
摘要
Abstract
Alluvial fans are prevalent sedimentary formations located at the outlets of mountain rivers or gullies.The analysis of their morphometric characteristics is essential for understanding the spatial heterogeneity and developmental factors influencing these landforms.As a typical humid alpine region,the Parlung Tsangpo Basin in southeast Tibet hosts a diverse array of alluvial fans at gully mouths.This dataset includes morphometric measurements and fan types for 133 alluvial fans and their contributing catchments across various sub-regions in the Parlung Tsangpo Basin,including the main stream of Parlung Tsangpo and its three major tributaries:Quzong Tsangpo,Bodui Tsangpo,and Yigong Tsangpo.Data collection spanned from 2022 to 2025 using Google Earth Pro,remote sensing imagery,field surveys,and statistical analysis.The collection and processing procedures adhered strictly to rigorous quality control standards and standardized protocols.This dataset provides a robust foundation for investigating the morphometric characteristics and variations of alluvial fans under different environmental conditions and spatial scales.关键词
