Ecosystem services (ESs) are the largest benefits that humans derive directly or indirectly from ecosystems. Inland river basins in arid zones have a variety of key ecosystem functions. At present, inland river basins are experiencing a decline in ESs, such as shrinking lakes, land degradation, and rapid biodiversity loss.

High concentrations of heavy metals (HMs) in urban surface dust (USD) can be extremely hazardous to urban ecology and human health. Oasis cities are located at the edge of deserts and are more exposed to salt/sandstorms, and they face a significantly higher accumulation of USD than wet or semi-humid areas. However, systematic studies on the pollution and risk assessment of HMs in USD in oasis cities have rarely been conducted.
