Agricultural Restructuring Based on the Water Resources Carrying Capacity in Shandong Province, China

Abstract

The agricultural production in Shandong province is top the list in our country. Available irrigation water has become shorter because quantity of agriculture water use is larger in a part of Shandong, water environment being worse. The contradictory relations between agricultural water and available water resource as well as water environment are analyzed in typical areas, such as groundwater overdraft area, seawater intrusion area and agricultural production areas along the polluted river. The results showed that water resource cannot support the existing mode of agricultural production in these areas. It is suggested to promote agricultural restructuring based on the quantity and quality of the local water resource. Vegetable production bases are moved from Shouguang (in Weifang city of Shandong province, China) to the areas along the Yellow River. The export of vegetables will be reduced. To improve the guarantee degree of water supply, the crop production along the polluted river will be replaced by fast-growing plantation or the surface water irrigation will be changed into exploitation of groundwater. It is suggested to generalize water-saving irrigation system, reduce the amount of agricultural water and improve the utilization efficiency of water resources.
