Leeks are Allium ampeloprasum. Dacong are Allium Fistolum.
Leeks are more onion-y while dacong functions mostly as a large scallion. They're often the preferred to scallion in northern china where it is used in a similar way as the south uses scallion.
Here's a photo comparing (in order from left to right) dacong, leeks, and scallions.
Well, these names are highly variable in different parts of the world. Even within China. Some of my Chinese dictionaries give 'leek' as the translation of 大葱 (dà cōng); some don't. The supermarket I bought them in describes them as 韭葱 (jiǔ cōng) which also means 'leeks'.
