Available water resources and effective water resources available were analyzed by using water functional district as the computation cell.

Application of S-P generalized model to analysis of water environmental capacity in Linyi water function area;

Current water quality with the demand water quality of water function area is compared and evaluated by synthetic analysis.

According to the water quality target,designing rate of flow,and water of function,based on the investigation of water quality,adopted the corresponding calculation model to calculate the acceptable filth ability of Baoding City water function areas.

Based on monitoring data of key water functional zones in Jiangsu, analysis and assessment about water quality & standardized rate of key water functional zones in Jiangsu are made.

The integrated assessment method of available water amount according to target water quality of water functional zone is introduced.

Water quality protection measures of water function regions in the Qingpu and Songjiang districts of Shanghai;

This paper reviews briefly the course of development of water function regions division and present working situation.

Based on study of the river network in Taihu Basin and schematizing water function regions,a water quantity and quality model was established.
