Abstract:  Sub-entry indexes of water resources pressure and their computing methods were proposed from the population quantity pressure, water resources pressure, water environment pressure, water resources technical pressure, water resources economy pressure and water resources lack pressure. They are what is called comprehensive indexes of water resources pressure They were used for calculating water resources pressure indexes of different cities of Zhejiang Province in 2008. The results obtained from comprehensive indexes showed that the water resources pressure was greater in Jiaxing, Wenzhou, Zoushen etc., while less pressure was in Linshui, Hengzhou, Huzhou, Quzhou etc.. The sub-entry index results indicated that ∶ the population quantity pressure and water resources pressure were greater in Jiaxing and Zhoushan, water environment pressure was less in Shaoxing, water resources technical pressure was more greater in Wenzhou, Water resources economy pressure was more great in Quzhou. Region economic and social sustainable developments can be realized by adjusting water resources utilizing mode to relax water resources system pressure.
