A Study on Dust Storm Pollution and Source Identification in Northwestern China.

In April 2023, a major dust storm event in Lanzhou attracted widespread attention. This study provides a comprehensive analysis of the causes, progression, and dust sources of this event using multiple data sources and methods. Backward trajectory analysis using the HYSPLIT model was employed to trace the origins of the dust, while FY-2H satellite data provided high-resolution dust distribution patterns.

Research trends and areas of focus on water rights: a bibliometric analysis 1971-2020.

This study investigated the research trends, key areas, and directions of water rights (WRs) using bibliometric data based on the Science Citation Index Expanded (SCI-E) and Social Sciences Citation Index (SSCI). This paper presents a comprehensive review of annual output, research fields, cooperative networks, published journals, and hot spot evolution from 1971 to 2020. The results show that the number of published papers on WRs has an exponential upward trend.
