I have a crawlspace in the basement that has a dirt floor right
now. I'd like to lay some sheets of 4x8 plywood (or other
material) on it to make a surface suitable for crawling on or
putting things on.

For crawling, a few planks of 1/2" plywood (exterior) would be
useful.
For storage, consider that you'd like ventilation around the stored
items; I'd try some old pallets, with optional 'wood preservative'
painted on (they won't weather, so stain or real paint are a waste).
I'm lazy, I just strap on some knee pads and a hard hat when it's
time to crawl.

Good ideas here. I have to admit that when i first posted, i wasn't
thinking about the termite angle. I like the idea of the concrete
but i have a feeling i'd make a mess of it as i don't know what i'm
doing. However, the paver idea sounds interesting. I priced it and
the pavers cost the same per square foot as 3/4" plywood and they
would last indefinitely. However, that's also something i've never
done. Do i just level the ground and lay the pavers on top letting
gravity keep them in place or is there something else i need to do to
secure them?

Use pressure treated ply and termite concerns go away.

Around here - central Florida - a sheet of PT 1/2" x 4' x 8' is about 25
bucks. That's about $0.78 sq/ft; pavers run from about $2.00 sq/ft up. An
exception is a 12" x 12" x 1 3/4" concrete "stepping stone"' that is $1.31.
