So uh… my fort at the moment has around 106 dwarves/petitioned entertainers and 20 visitors. The problem is (and this occurred suddenly) is that the FPS has been reduced to ~4 FPS. This is unplayable for me. Is there any way I can restore the FPS back to at least 20?
Ny way I can avoid death by FPS in Dwarf Fortress

The wiki has a great guide to exploratory mining.
Otherwise, the map is generated at random, so the only way is to try.
So from what I gather is that you want to create a specific map or decrease the temperature on an already created map. I don't know the latter but I can help with the former:
- Open up DF
- On the main screen select Design New World With Parameters
- Select one of the presets and press the e key
- Scroll down till you see the following (should be the second page):
- Change the Maximum Temperature and Minimum Volcanism values
- good values for Temperature are ~45
- good values for Volcanism are >50
- Finally, to ensure a good Taiga you'll want to play with the Rainfall parameter.

Most of this advice comes from the wiki page on improving framerate. Some of it unfortunately requires pre-action, before your current point.
A number of things can impact framerate. Flowing water for example takes a lot of CPU power. Item count can affect it, though number of squares with items in them affects it more. Pathfinding can cause trouble.
I find that creature count is my biggest offender, but I don't generally have large amounts of flowing liquid in my forts.
However changing the structure of your fort with framerates that low is going to be a pain and a half. There are some things you can turn off in configuration files that may help. The important file here is df/data/init/d_init.txt. In this file you can adjust things like the population cap which would let you avoid having too many dwarves in the first place. You can also turn off temperature calculations which can speed up the game some.
Not knowing a huge amount about your setup, I would recommend turning off temperature, at least temporarily, to get enough speed to work with. Be sure to also reduce your population cap. Otherwise your population will just keep growing and slow you back down again.
I would also confine all your animals to walled off pastures or cages and close off unneeded areas to reduce pathfinding slowdowns. If you have any waterfalls or pumped areas, turning them off could also help.
Some people don't like to use what feels like a bug, but quantum stockpiles can help. Geting all the random junk consolidated is supposed to help framerate.
If some of the random items are things you will never want, like XXPig tail sockXX, You can use a Dwarven Atom Smasher to remove them from the game and no longer spend any CPU cycles at all tracking them. This however is going to be a minor improvement at best, unless you have tens of thousands of worn out socks.
Look at the framerate wiki page and see if any of its other ideas apply in your situation.
