Yield represtents the amount of Food, Hammers and Commerce the terrain type gives when worked unimproved. For Terrain Features the number given is the bonus / malus to the normal value. Health indicates any Health bonus/malus the terrain gives to nearby cities. Move means the (extra) movement cost for this terrain, while defense is the extra defense. Please note that these bonusses stack. So a hills with a forest has +2 move and +75% defense. And while a Floodplains is given as +3 food, you will always see them as 3 / 0 / 1 because they are always next to a river.
The improvements listed are exhaustive. Improvements not listed can not be build. For the base terrain types, the resources listed are the ones that can be build without any terrain features. Special resources are not counted here. The specific improvement for a resource can always be built, no matter what the terrain type or terrain features.
The occurances for terrain features are what you normally see in the game. Using the world editor it is possible to make other arrangements, such as floodplains on top of grassland-hills. The bonusses / malusses given in this table should still be correct, you should just add them for each terrain feature. You will never see such arrangements in normal games though.
