Analysis of the relationship between food production, water resources and power consumption in North China

Abstract

The article selected the North China Plain, a concentration zone of the Huang-huai-Hai major grain production region, analyzed the relationship between grain production and the consumption of water and power through statistics data. The results show that the development of the irrigation agriculture greatly promoted the increasing of the grain production in the study area; and the groundwater is still dominant water resources in the farmland irrigation although there are the decreasing trend of the total water utilization amount and consumption structure of the increase of surface water consumption. And, the exponential relationships are obvious between groundwater consumption and the food output, as well as between groundwater consumption and power consumption in irrigation and drainage production process. The mutual relationship of the three has indicated that the exploitation of ground water within the region has greatly promoted food productivity and further increased power consumption.
