水资源问题应引起关注

我国水资源量占世界水资源总量的8%，但要维持占世界人口总数21.5%的人类活动。除人均水资源少外，我国人口、耕地和水资源分布不均衡，长江以北耕地面积占全国耕地面积63.5%的重要农耕地区，仅有水资源的19%。此外，水资源与化石能源呈逆向分布，主要的煤炭、石油产区都在缺水区域。我国的降水在时间上不均衡，降雨量的60%以上集中在6~9月，易形成洪水，不仅无法利用，而且易形成洪涝灾害。 我国目前年用水量约5700亿m3，但北方地下水已严重超采，北方各主要河流的泾流利用率都超过国际上的通行标准，污水排放量增加而污水治理欠帐过多。用水结构中，产值低的农业耗水过大，使我国水资源形势十分严峻。据此，全社会应从政治、法律上重视水资源问题，用经济手段管理水资源，并在全社会重视节约用水的教育和措施。

WATER RESOURCE SHOULD BE EMPHASIZED

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.
