Data availability in china on physical supply and use tables

Supply table

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.

Use table

  • 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.


Data availability in china on physical supply and use tables

Use table (sources-based)

Sources-based water use means the gross water including the losses during its transportation supplied to users by various water sources engineering.

Storing

diversion

Surface water

lifting

transferring

Shallow

groundwater

confined

Light salty

Treated water

Other sources

Rainfall collection

Sea water


Data availability in china on physical supply and use tables

Use table (user-based)

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.

Water uses for nation-owned and scale-above industries

Water uses for nation-owned and scale-bellow industries

Industrial water use

Water use for thermal (nuclear) power generation

Issues faced

  • Conflicts of classification with ISIC or more combined classification not meets ISIC

  • Lack of information from monitoring, metering and investigation, of which some figures have to be estimated

  • Hard jobs of coordination among various agencies for various information related
