2. 2 Outline Use Table General Supply Table Issues

3. 3 China Institute of Water Resources and Hydropower Research General North China Water Resource Bulletins from 1994 to 1996 China Water Resource Bulletins from 1997 to 2005 Water statistics related with PSUT in China Water statistics from MWR Industrial water use statistics from bureaus of statistics Integrated water resources planning Water resources utilization Annual Typical year

4. 4 China Institute of Water Resources and Hydropower Research Counties Provincial Nation Profectures River basins Administrative checkup Statistics Process General

5. 5 China Institute of Water Resources and Hydropower Research Supply Usage Consumption Discharge Classification Checkup Balancing checkup Statistics Process General

6. 6 China Institute of Water Resources and Hydropower Research Statistics units River basins Administrative regions Overlapped areas Administrative regions River basins General

7. 7 China Institute of Water Resources and Hydropower Research 10 hydrological regions at 1st class 31 provinial regions 750 statistics units overlapping prefectures and hydrological regions at 2rd class

8. 8 China Institute of Water Resources and Hydropower Research 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

9. 9 China Institute of Water Resources and Hydropower Research 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. Supply table

10. 10 China Institute of Water Resources and Hydropower Research 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. Use table

11. 11 China Institute of Water Resources and Hydropower Research Surface water groundwater Other sources Sources-based water use means the gross water including the losses during its transportation supplied to users by various water sources engineering. Shallow confined Light salty Treated water Rainfall collection Sea water Use table (sources-based) Storing diversion lifting transferring

12. 12 China Institute of Water Resources and Hydropower Research 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 Use table (user-based)

13. 13 China Institute of Water Resources and Hydropower Research Irrigation use Forest, animal husbandary and fishery Paddy field Irrigated field Vegetables field Orchard & forest Grassland Fish pond Agriculture use Agricultural water use Fruit Nersery Eonomic forest Artificial Feedingstuff

14. 14 China Institute of Water Resources and Hydropower Research 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 use for thermal (nuclear) power generation Industrial water use Water uses for nation- owned and scale- bellow industries

15. 15 China Institute of Water Resources and Hydropower Research Domestic water uses Dom estic Urban Rural Public household livestock Service (3rd industry) Construction

16. 16 China Institute of Water Resources and Hydropower Research Ecological water uses ecology Urban env. suppleme ntary Artificial water distribution excluding precipitation and runoff lakes virescence cleaning lakes swamps

17. 17 China Institute of Water Resources and Hydropower Research available for users not ISIC sectores available Some from WRM and NBS respectively Only total discharge from industrial and domestic uses available

18. 18 China Institute of Water Resources and Hydropower Research 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 Issues faced
