1 时势造就高科技产品,廉价高效极具推广应用价值水资源短缺,已成为全球性问题。我国是世界上主要贫水国之一,人均水资源不足世界人均水平的1/4,且随着改革开放的不断发展,工农业生产的突飞猛进,人民生活水平的日益提高,对水的需求量呈几何增长,水资源供需矛盾日益突出。特别是对于人口第一的河南省来说,用水形势更加严峻:人均水资源只有460m~3,约为全国人均水量的1/5,居全国第22位,每公顷平均水资源量不足400m~3,居全国第24位,属联合国指定的贫水区。河南作为一个农业大省,发展节水型农业不仅是
1 times to create high-tech products, cheap and highly useful value Promote water shortage, has become a global problem. China is one of the major water-poor countries in the world, with per capita water resources less than 1/4 of the world average. With the continuous development of reform and opening up, the production of agriculture and industry has been advancing by leaps and bounds, and the living standard of the people has been increasing day by day. The demand for water Geometric growth, the contradiction between water supply and demand has become increasingly prominent. Especially for the first population of Henan Province, the water situation is more serious: the per capita water resources is only 460m ~ 3, about 1/5 of the national average per capita water, ranking No. 22 in the country, the average water resources per hectare less than 400m ~ 3, ranking 24th in the country, belonging to the United Nations designated water area. As an agricultural province in Henan, it is not only the development of water-saving agriculture
