Dust storms (DSs) originating in East Asia impact ecosystems, climate, and public health China. Although DS frequencies have declined since the 1950s, extreme DSs spring 2021 had major effects on air quality over northern Based daily records during 1979–2021 K-means clustering, we define two types (T1 T2) China, accounting for 18.7% 81.3% of DSs, respectively. T1 mainly Gobi Desert, predominant...

Primary Production and Precipitation Knapp and Smith (1) suggested that interannual variability in aboveground net primary production (ANPP) is not related to fluctuations in precipitation, based on analysis of data from 11 Long-Term Ecological Research sites across North America. This finding, if applicable to other regions, is crucial to climate change research, because it may necessitate rev...

Identifying the provenance of aeolian deposits in semi-arid zones China is beneficial understanding Earth’s surface processes and helping to alleviate ecological stress. In this paper, we use grain-size, geochemical elements, heavy-minerals, quartz grain morphology data investigate potential source sands from Ordos Deserts (Mu Us Sandy Land Hobq Desert). Sedimentological, geomorphological resul...

The xerophytic desert shrub Haloxylon ammodendron (C. A. Mey.) Bunge. is distributed naturally in Asian and African deserts, and is widely used for vegetation restoration in the desert regions of Northern China. However, there are limited long-term chrono-sequence studies on the impact of changed soil properties and vegetation dynamics following establishment of this shrub on mobile sand dunes....

Rainfall events can be characterized as "pulses", which are discrete and variable episodes that can significantly influence the structure and function of desert ecosystems, including shifts in aboveground net primary productivity (ANPP). To determine the threshold and hierarchical response of rainfall event size on the Normalized Difference Vegetation Index (NDVI, a proxy for ANPP) and the diff...
