| Main problem for sustainable utilization of agricultural water resources in China is the coexistence of both shortage and waste of water resources in the irrigation areas in China.It is difficult to form effective water-saving mechanism under the present system and policy.With irrigation projects getting old,facilities weak and water resources unreasonably used,the ecological environment is worsening.The influence of price-making policy to sustainable utilization of agricultural water resources in irrigation areas is elaborated,and ideas to reform the price system to promote water-saving agriculture are proposed.The present situation and the existing problems in water-saving agriculture are discussed,such as lack of technology popularization,deviation on theoretic knowledge,lack of integrated technology,low level of technical innovation and insufficient investment.It is pointed out that the improvement of sustainable utilization of agricultural water resources in irrigation areas relies on setting up the sustainable utilization idea,developing vigorously water-saving agriculture,reforming existing management system,establishing highly effective water resources management pattern,water-saving mechanism and democratic management mechanism to promote united utilization of surface water,ground water and precipitation. |
