供给表

• In china, there is no corresponding statistics for supply table while discharges from each industrial sector and domestic water uses can be regarded as the supply to environment in SEEAW. It can occasionally be found that some sectors, say ISIC 36, supplies to other sectors only at prefecture or lower level. These can not meet the supply table in SEEAW.

Supply table

• Water consumption in supply table is estimated

from typical investigation in China, is not

obtained from the difference between supply

and use tables

• Consumption means the evapo-traspiration,

soil absorbing, product taking-off, drinking etc.

during water transition and using which can

not return to any water body in nature.

• Both sources-based water abstraction and user-based water supply in Chinese statistics can be located in use table of SEEAW and only the total value without breakdown values can be filled in.

User-based water use means the gross water including the losses

during its transportation distributed to each user. Therefore both

user-based and sources-based water are equal.

The users are quite different from ISIC.

Four main categories for water users are:

- Agriculture

- Industry

- Living

- Ecology

Industrial water use

It indicates the water used in manufacturing, processing, cooling, air conditioning, decontaminating, washing etc. in producing of industrial and mining enterprises. It is calculated only for fresh water abstraction and does not include reused water in the industrial internals.
