末次冰期千年气候事件5-7的瞬变气候模拟

该数据集是利用气候模型COSMOS运行的，37.5-32kaBP轨道变化瞬变试验TRN40ka，来自Zhang et al（2021, Nature Geoscience，https://www.nature.com/articles/s41561-021-00846-6）。具体的试验设计请参考原文献。 COSMOS（ECHAM5-JSBACH-MPI-OM）是德国马普所研发的海洋大气植被耦合气候模型。大气-陆面模块ECHAM5-JSBACH的空间分辨率为T31(∼3.75°)，垂直19层；海洋模块MPI-OM是不规则网格，水平分辨率为 (3°×1.8°) ，垂直40层。

Fungal spores data and (Ce+Fa/Po+Fa) ratio data from Gonghai Lake over the past ~2000 years

The data sets contains the content of fungal spores and (Ce+Fa/Po+Fa) ratio data from Gonghai Lake (38°54′N, 112°14′E, altitude 1860 m) in northern China over the past ~2000 years. We calculated pollen (Ce+Fa/Po+Fa) ratio of 321 samples and we identified the fungal spores of 216 sedimentary samples to reconstruct changes in cultivation and grazing intensity over the past ~2,000 years in northern China. Time-series analysis reveals that the arable farming phases had a longer periodicity than the grazing phases, possibly because of the greater resilience of the former to climate change and the attachment of agriculturalists to their land. Our findings potentially help improve our understanding of the impact of land use on soil degradation. The data is stored in Excel format.

乱海子湖泊岩芯粒度数据集（0-859 cm）

乱海子钻孔（LHZ18）于2018年8月兰州大学黄小忠课题组获得，本数据为祁连山乱海子湖泊岩芯0-859 cm的粒度数据。0-4 m按照一个样进行粒度分析，4-8.6 m隔一个样进行粒度分析，共获得390个数据；实验在兰州大学西部环境教育部重点实验室完成，利用Mastersizer 2000仪器进行了粒度分析；该数据反应了该湖泊沉积物的粒径变化，对青藏高原长时间序列风沙活动的研究具有十分重要的作用。
