中亚迁飞区青藏高原路线与范围图（2023-2024）

《中亚迁飞区青藏高原路线栖息地分布图》基于青藏高原及周边地区的多物种野外跟踪监测数据，通过对黑颈鹤、蓑羽鹤、斑头雁以及棕头鸥佩戴卫星追踪器后获取的逐小时定位点，采用核密度估计（Kernel Density Estimation, KDE）方法构建而成。黑颈鹤贯穿青藏高原南北，核心栖息于藏北湖盆与雅鲁藏布江河谷；蓑羽鹤跨国迁徙至蒙古高原/印度，依赖青藏高原腹部湿地停歇；雁鸭类集中于高寒湿地；鸥类则喜好高原湖泊。栖息地按密度划分为核心区（繁殖/越冬）、次级区（停歇补给）及广域潜在生境。研究明确了鹤类与雁鸭类偏好湿地，并刻画了跨越中、印、蒙等国的生态廊道，为跨国保护协定、栖息地管理及减少人类干扰提供了科学依据。

Habitat Distribution Map of the Qinghai-Tibet Plateau Route in the Central Asia Migratory Flyway. This dataset is developed using multi-species field tracking and monitoring data collected across the Qinghai-Tibet Plateau and its adjacent areas. Hourly positioning points were acquired via satellite trackers attached to black-necked cranes, demoiselle cranes, bar-headed geese, and brown-headed gulls, with the Kernel Density Estimation (KDE) method employed for construction. Black-necked cranes migrate across the north-south expanse of the Qinghai-Tibet Plateau, with their core habitats concentrated in the northern Tibetan lake basins and the Yarlung Zangbo River Valley. Demoiselle cranes undertake cross-border migrations to the Mongolian Plateau and India, relying on wetlands in the central Qinghai-Tibet Plateau for stopover and refueling. Anatidae (geese and ducks) primarily gather in alpine wetlands, while gulls favor plateau lakes. Habitats are categorized into three tiers based on density: core areas (for breeding and overwintering), secondary areas (for stopover and supplementary feeding), and broad-scale potential habitats. This research clarifies the wetland habitat preferences of cranes and Anatidae, and delineates transnational ecological corridors spanning China, India, Mongolia and other countries, providing scientific underpinnings for transnational conservation agreements, habitat management, and mitigation of human disturbances.

背景概述

该数据集基于黑颈鹤、蓑羽鹤、斑头雁和棕头鸥的卫星追踪数据，采用核密度估计方法绘制了2023-2024年青藏高原及周边地区的物种栖息地分布图。它揭示了不同物种的分布偏好（如鹤类依赖湿地、雁鸭类集中于高寒湿地），并将栖息地划分为核心区、次级区和潜在生境，为跨国生态保护与栖息地管理提供了科学依据。
