Discussion on the Urgency and Ways of High-Efficient and Water Saving Agricultural Construction in the Yellow River Basin
|
Abstract:
The Yellow River Basin is located in the arid and semi-arid region in the north of China, where less river runoff and precipitation is the basic source of water resources. The basin is with seriously scarce water resources in China, even less in the world. Because of water resource shortage, the imbalance between supply and demand is sharp day by day in the Yellow River Basin. On the basis of analyzing the general utilization of water resources and the urgency of high-efficient and water-saving agricultural construction in the Yellow River Basin, the potential of high-efficient and water-saving agricultural construction is estimated in this paper. Then, the ways of high-efficient and water-saving agricultural construction is discussed based on the characteristics of water resources and the agricultural situation in the region upwards, middle and catchment area of Yellow River Basin. As a result, it is a necessary choice to transform from traditional irrigated agriculture and rain fed fanning to high-efficient and watersaving agricultural construction irrigation and modem dry farming in order to realize the sustainable utilization of water resource. The analytical results and conclusions of this paper will provide scientific basis for sustainable agricultural development in the Yellow River Basin.
