沙漠生态系统是生态系统多样性的典型代表。 

在富庶的关中平原，自古就有一片袖珍、狭长的沙漠——大荔沙漠。 

从学术的角度，沙漠是无人定居、缺水干燥的沙石地带，然而这片沙漠却水草丰美、物产丰富。所以面对这片特殊的沙漠，我们产生了很多疑问：大荔沙漠何时形成？怎样形成？大荔沙漠是真正的沙漠吗？ 

通过采访、实地考察、查阅资料、制作模型以及实验对比，我们知道了这片沙漠的来源，也澄清了这片沙漠并不是真正意义上的沙漠。

Desert ecosystems are typical of ecosystem diversity. 

In the rich Guanzhong Plain, there is a pocket, narrow desert — the Dali Desert! Information shows that this desert has been here since ancient times. 

From an academic point of view, the desert is a lifeless, dry sand and stone area. However, this desert is rich in water and grass. It is rich in property. When we faced this particular desert, we had a lot of questions: When was the Dali Desert formed? How did it form? Is this area a real desert? 

Through interviews, field trips, searching the information, modelling, and experimental comparisons, we answer our questions and clarify that the Dali Desert is not a real desert.
