The total water resource volume in our country is 8% of the world,but it must keep 21.5%
Human activities of the world population.The distibution of the population,the piough land and
The water resource in our coutry are unbalanced except for the lack of the average per water resource.The agriculturala area in the north of the Yangtze Rever is 63.5% of the main agricultural area among the total plough land ,but the water resource volume is only 19%.Moreover,the distribution of the water resource and the fossil energy is revese and the major coal mineral and the oilfied are lacated in the area which are short of water.From the point of time,our country precipitation is unbalance,more than 60% rainfall volume concentrates from June to September,it is not only difficult to utilize,but also easy to from the flood prone disaster.
  At present ,the water consumption volume in our country is abuut 5.7*10*11 cubic meter of the year,but ground water in the north has been over produced seriously,the run off flow usage rate of the main rivers in the north are all beyond the internation general standard,the discharge amount of the sewage increases but the harnessing of sewage  isn't enough.On the construction of the water consumption,agricultural water consumption is large,but its production value is low,and it leads a very serious for our country waterresource.So the whole society should pay much attention to the waqter resource from points of the politics and law ,we must use the economical method to manage the water resource and emphasize on the education and action for saving water in the whoie society.
