I made a dirty update to the DF2014:World_generation wikipage with some tables.

Someone with more experience in advanced world gen parameters may translate the Natural Savagery info below into a more understandable format and add it to the wiki.
Here is a short summary.

World Size
limits maximum number of forgotten beasts, civilizations, sites and beasts.

each world size has a fixed number of forgotten beasts at the beginning of year one. ( 12 / 27 / 75 / 243 / 867 )

Number of Civilizations
in combination with world size sets the civilization cap

i.e. a pocket world with very high number of civilizations setting can contain up to 10 civilizations, but they are not distributed equal so you may end up with:
Dwarf:3 Elf:0 Human:2 Kobold:2 Goblin:3

a large world with very high civilizations may contain:
Dwarf:7 Elf:29 Human:57 Kobold:56 Goblin:10

medium worlds with very high civilizations will fail world gen 99% of the time as there is not enough room for 160 civs.

Maximum Number of Sites
in combination with world size sets the sites cap

Less sites mean existing civilisations can not expand to many new settlements over the years passing. Very low site numbers result in only the civilizations home settlements exist after year one with a high probability of getting eradicated by some event.

High site numbers increase the duration of history generation by a huge amount.

Site number examples:

Small world size - 125 years history - 10 civilizations - various site caps - same seeds per test
CIVS: Dwarves: 1, Humans: 2, Elves: 2, Kobolds: 2, Goblins: 3

Sites

Total Sites 165 267 333with 10 sites cap all good sites were destroyed by year 125

Total Population

Human 67 1562 2766
Elf 74 668 1162
Kobold 255 336 394
Goblin 1475 1805 2084
Number of Beasts
in combination with world size sets the beast cap

pocket and smaller worlds with very low / low number of beasts may only contain a single semi-megabeast and no megabeasts / titans.

Natural Savagery
defines the amount of benign, neutral and savage surroundings

influences the following world gen parameters

[SAVAGERY_FREQUENCY:X:X:X:X:X:X]

3:5:4:3:2:1 - very low
3:3:2:2:1:1 - low

3:1:1:2:2:3 - high
3:1:2:3:4:5 - very high

SIZE: pocket: 17*17-1 ,smaller: 33*33-1 ,small: 65*65-1 ,medium: 129*129-1 ,large: 257*257-1

very low  - (25% * SIZE)    : (12,5% * SIZE)  : 0

Neat!

Can't you generate a world with the parameters you want, then go to legends and export the generation info? That should tell you everything you want to know and then some.

That's what i did... and adding the values to the df wiki.
