Research on water-saving reform modes on the paddy irrigation district in Northeast China

Northeast China is the traditional old industrial bases and one of the main marketable grain bases, in which the paddy planting area occupied 72.0% of that in the north of China. And the agricultural water-use amounts to 70% of the total water consumption in Northeast region, among which about 95% was utilized for paddy field irrigation. In this study, we investigate the actual problems and difficulties in the Northeast rice irrigation districts in the recent years, such as the reducing irrigation water supply, waste of agricultural irrigation water-using, low water price, low efficiency of water management, old and unmatched water conservancy facilities, and so on. According to the serious situation, some concrete Water saving reform modes were put forward to promote the sustainable development of Northeast China irrigation districts.
