Oasis agriculture is a unique agricultural practice that thrives in the middle of arid (干旱) and semi-arid regions where water is a limited resource. These areas, often found where underground water sources meet the Earth's surface, create rich soil in the desert, supporting a variety of cro...

The observed co-variation of grain size, soil nutrients and geochemical ratios of the surface samples shows that our approach can be used to determine the trends of past oasis-desert evolution. The reconstruction suggests that oasis formation largely depended on the development of a fluviolacustrine...
Desert travel and living would be nearly impossible if it wasn't for the existence of a unique landform: the oasis. In this lesson, you'll learn what elements are needed to create an oasis, where they are found, and what plants grow there. What Is an Oasis? Imagine it's the year ...

Scenario analysis of ecosystem services (ES) can provide a scientific basis for ecosystem management. The objective of this study was to reveal the effects of future land use scenarios on ES in a mountain-oasis-desert system (MODS). We first simulated la
