Habitability

 宜居性（Habitability） is the measure of how comfortably a species can live on a planet. Most species have a climate preference for one of the primary habitable planet types, although more exotic preferences are possible. A planet's habitability for a given species is determined by how closely its climate matches that species' preference. The 9 regular habitable world types are divided into 3 climate categories: dry, frozen, and wet.  环形世界（Ring World）s,  盖亚星球（Gaia World）s, and  都市星球（Ecumenopolis）es have maximum habitability for all species, while  死寂星球（Tomb World）s,  机械星球（Machine World）s, and  蜂巢星球（Hive World）s (except for  蜂巢思维（Hive-Minded） species) normally have   0% 宜居性（Habitability） for biological species.

Tier	Base
Gaia World, Ecumenopolis, and Ring World	100%
Hive World for  蜂巢思维（Hive-Minded） species	100%
Exact match	80%
Habitat	70%
Climate category match	60%
Climate category mismatch	20%
Tomb World, Machine World, and Hive World	0%

• Every 1% reduction of habitability below 100% increases pops'  （） and  amenity usage by +1% and reduces their job output and species growth by -0.5%. It floors at 0% Habitability, giving +100% pop upkeep and amenities usage, and -50% job output and pop growth.
• Homeworlds have +30% habitability for the species originating from them.
• Robot pops have 200% habitability for each planet type, but empires that aren't  机械智能（Machine Intelligence）s require the  智能人（Droids）nology to build colony ships using robots.
• Low Habitability can trigger various events.

Visual cues

Systems containing habitable worlds will have one or more planet icons that are either green, yellow, orange, red, or blue – depending on the habitability percentage and/or status of the planet(s) in question. Planets with the  环境改造候选（Terraforming Candidate） modifier don't create planet icons unless they are being  环境改造（Terraforming）ed.

Icon color	宜居性（Habitability）
Green	The world is ≥ 70% habitable for at least one species in the player's empire.
Yellow	The world is 40–69% habitable for at least one species in the player's empire.
Red	The world is < 40% habitable for all species in the player's empire.
Orange	The world is habitable but not surveyed.
Blue	The world is currently being terraformed.

Planets with an anomaly or a pre-FTL species cannot be colonized.

Habitability strategies

As only about ⅓ of planets will match the primary species preferred climate category, to fully and efficiently utilize all habitable planets in their own systems, an empire may want to populate its worlds with alien species, genetically-engineered subspecies, or even robots.

It is also possible to  环境改造（Terraforming） habitable worlds, though this is a costly and time-consuming process and requires the  地表塑造（Terrestrial Sculpting） technology to be researched. Only habitable planets and barren worlds with the  环境改造候选（Terraforming Candidate） modifier can be terraformed.

Genetic Modification

Using genetic modification, it is possible to create a subspecies of the empire's primary species with a different climate preference. However, as genetic modification targets all pops of the same subspecies on a planet, this needs either a first-in approach, requiring suffering through low habitability until the project is completed, or modifiying the pops on an existing colony, preferably one with increased habitability regardless of current climate preference (Ringworld, Habitat, Homeworld, beneficial modifiers). In either case, the cost of modifying pops will delay researching  社会学研究（Society Research） technologies.

Changing a habitability trait costs the equivalent of adding a trait worth 3 trait-points and requires the  腺体适应（Glandular Acclimation） technology.

Xenos

With all the possible climate preferences, it is likely that some alien species can live comfortably on planets which are unsuitable to the empire's primary species. The main disadvantage is that xeno pops might not have favorable traits. There may also be unwanted  亲外主义（Xenophile） attraction or faction interactions from this path.

Xeno pops can be added to an empire to use as colonists via conquest, migration treaties, or – with the  寰宇企业（Megacorp） DLC – the slave market. Empires can colonize with any species that has migration access to the empire, even if no pops of that species live on the empire's worlds.

Uplifting, Enlightening, or Infiltrating a pre-sapient or pre-FTL species is another way to acquire xeno pops. With the first, it's possible to get a rare climate preference trait like  死寂星球偏好（Tomb World Preference）. Species native to  死寂星球（Tomb World）s are extremely adaptive and can thrive on any planet – they have 60% habitability on every normal planet class. The usual way to obtain pops of these species is uplifting pre-sapients found on Tomb Worlds. The Horizon Signal event chain can also create a subspecies of the empire's main species with this trait. Alternatively, pops of the main species on Tomb Worlds may Self-Modify via the A New Species event and develop into their own species native to Tomb Worlds.

It is also possible to purchase pops with the  死寂星球偏好（Tomb World Preference） trait from  Racket Industrial Enterprise caravaneers.

Improving habitability

Aside from changing climate preference, there are also various other methods for improving habitability:

Colony ships

Colony ships allow an empire to settle habitable planets or megastructures in owned systems. When ordering the construction of a colony ship, the player is given the option of choosing the species or sub-species of the  人口（Pop）(s) that will be sent to the new colony. Species require the Colonization Allowed species rights to be selected for new colony ships. Pops are neither consumed nor transported in this process. Once constructed, the colony ship may be sent to any habitable world within an owned system to start a colony. Colony ships take one year to build and their upkeep cost is maintained throughout the whole colonization process. Colony ships can also be built through the interface of the planet to be colonized, which automatically queues the colonization order as long as the path is not blocked.

The cost of a colony ship depends mainly on the empire's primary species class and governing authority.

Primary species
Biological	200 合金（Alloys）  200 食物（Food）  200 消费品（Consumer Goods）	200 合金（Alloys）  500 食物（Food）	50 合金（Alloys）  1000 食物（Food）

Robot	400 合金（Alloys）

The  开拓精神（Frontier Spirit） ruler trait reduces the cost of colony ships by -35%.

Alternate colony ships

Meteorite Colony Ship

In addition to regular colony ships, empires with the  企业国度（Corporate Dominion） or  民营勘探者（Private Prospectors） civics can also construct Private Colony Ships, which cost  500 能量币（Energy Credits） instead. However, the starting pops on a new colony founded by a private colony ship will have random ethics, rather than one of the empire's governing ethics.

Similarly, empires with the  降世灾星（Calamitous Birth） origin can also construct Lithoid Meteorites, which cost  500 矿物（Minerals） instead, have no upkeep cost, and take only 150 days to build. Lithoid Meteorites also have a much faster sublight speed than regular colony ships. A planet colonized by a lithoid meteorite gains and two Buried Lithoids blockers and the  Lithoid Crater modifier, which adds   -50% 宜居性（Habitability）.

Colony development

When a Colony Ship lands on a planet, it will be converted into a tier 1 capital building, which can be upgraded further as the population grows. After landing, a period of initial development will occur. The period lasts about 2 years and 10 months at 0 pops, and grows with increasing number of pops. It can also be reduced by the following:

殖民地发展速度（Colony Development Speed） Source	Modifier
轨道居住站（Orbital Habitat）	+200%
Evacuation Protocols edict	+100%
人工智能殖民船（AI-Controlled Colony Ships） technology	+50%
自我意识殖民船（Self-Aware Colony Ships） technology	+50%
瓷金基础设施（Ceramo-Metal Infrastructure） technology	+25%
耐钢基础设施（Durasteel Infrastructure） technology	+25%
Adopting the 扩张（Expansion） tradition tree	+25%
开拓精神（Frontier Spirit） ruler trait	+25%
扩张主义（Expansionist）	+15%

While the colony is being established, it is extremely vulnerable: just a few days of orbital bombardment will wipe it out completely. During this period, the new colony does not produce anything and consumes  8 能量币（Energy Credits）. It is possible to remove  地块障碍（Tile Blocker）s while the colony is developing, however their clearance cannot be cancelled or reordered until the colony is fully established. Once the colony has been successfully established, a single pop of the species selected for the colony ship will appear on the planet. It is then possible to develop the planet by constructing  区划（District）s and  建筑（Building）s.

The  Colonization Fever tradition and the  尤特冷冻核心（Yuht Cryo Core） relic each increase the number of initial pops on a new colony by +1.  机械智能（Machine Intelligence） empires' colonies also start with +1 initial pop.
