^ Well, the most simple explanation I can give you is that one kanji alone can have meaning of word. For example, while 地球, chikyū, can be translated as earth, it's referring to our planet Earth. 地 alone means earth, as well as couple of other kanji(土 and 壌)

Basically, to translate Doryūsō(土流槍), we must look meaning of each kanji.
 * 土(tsuchi/do), as established, means earth.
 * 流(nagare/ryū), has several meanings, like flow or style, so depending on context, 土流 can be translated as "earth flow" or "earth-style".
 * 槍(yari/sō) means "spear"

I apologize if my explanation wasn't what you were looking for. I'm not exactly good at explaining things.
