环境改造 is the act of changing the planet classification of a
行星 in order to make it more
habitable for the empire's species. The base technologies requires significant
社会学研究 research to unlock and each terraforming project requires significant investments of
能量币 and
.
The first time a planet is terraformed, there's a chance of triggering a terraforming event. Terraformed planets can't get colony events.
Terraforming requirements[编辑 | 编辑源代码]
Terraforming is started via a button in Planet Detail view. The world must be surveyed and within your borders. Only habitable worlds and
barren worlds that have the rare 
环境改造候选 modifier can be terraformed. The expansion planner screen can be used to find these rare candidates.
It is possible to terraform inhabited planets if the empires has the
生态适应 technology. Doing so inflicts a -20%
幸福度 penalty on the planet for the duration of the procedure.

都市星球 worlds are created via
决议s rather than terraforming. They must be inhabited but pops do not suffer a happiness penalty during the process.
The following 
行星修正s are always removed when terraforming a planet:

苍茫大地

Irradiated

变幻莫测的天气

闹事的动物

狂野之风

Second Home
If the planet is being terraformed into either a
Machine or
蜂巢星球 the following modifiers are also removed:

致幻大气

催情大气

郁郁葱葱

自然景观
If the planet is terraformed into a Machine World, the 
Paradise Made modifier is also removed. Additionally, if there are any
Pops on the planet without the
神经机械,
机械体, or
机械 traits, they're all killed and an
Organic Slurry deposit is added.
When and if terraforming a planet to Hive or Machine World, keep in mind that all planetary features, excluding a few rare ones that give access to rare resources, will always be removed.
