In the map, we can see the map of China Hunan hydrogeological map. The scale of the map is 1:1750000. The descriptive datas of the map are water bearing rock group and its water rich degree, representative water points,etc.

1.Aquiferous rock group and its water richness

(1) Loose rock-like interstitial water-bearing rock group

(2) Clastic rock voids and water-bearing rock group:

①Clastic rock pore fracture water-bearing rock group

②Clastic rock type carbonate rock type water rock group

(3) Carbonate rock fracture karst aquifer group:

①Carbonate-bearing aquifer

②Carbonate-like clastic rock-like aquifer

(4) Magmatic rock fractured water-bearing rock group:

①Intrusive rock aquifer

②Water-jet rock type

(5) Metamorphic rock fractured water-bearing rock group

2.Representative water points and others
