A dataset of lake-catchment characteristics for the Tibetan Plateau (v1.0)

Lakes collect runoff, sediment and nutrients from upstream watersheds and are an important "destination" of material migration at the watershed scale. Therefore, the attributes of lake water and sediment are affected by catchment attributes (e.g. climate, terrain and vegetation conditions) to a large degree. This dataset delineates the watershed boundaries of 1525 Lakes (with an area from 0.2 to 4503 square kilometers) on the Tibetan Plateau, and calculates 721 catchment-scale attributes on the aspects of lake body, terrain, climate, vegetation, soil/geology and anthropogenic activities. This is the first dataset of lake-catchment characteristics on the Tibetan Plateau, which can provide foundamental data for the study of lakes in the Tibetan Plateau. <br> <br>

湖泊会汇集上游流域的径流、沉积物与营养物质，是流域尺度物质迁移的关键汇点。因此，湖泊水体与沉积物的属性在很大程度上受集水区（Catchment）属性（如气候、地形与植被条件）的影响。

本数据集绘制了青藏高原1525个面积介于0.2至4503平方千米的湖泊的流域（Watershed）边界，并从湖泊本体、地形、气候、植被、土壤/地质以及人类活动等维度计算了721项集水区尺度的属性特征。本数据集是首个针对青藏高原湖泊-集水区特征的数据集，可为青藏高原湖泊相关研究提供基础数据支撑。
