摘　　要：[Objective] The aim was to study the effects of water supply and consumption on water saving and drought resistance. [Method] Controlling field experiment was conducted to explore water balance between supply and demand in paddy fields in hilly regions in Sichuan Province. [Result] Rainfall in hilly areas was 3 611.10 m3/hm2; water for irrigation was 6 299.25 m3/hm2; evapotranspiration of rice was 6 424.95 m3/hm2; deep leakage was 2 459.55 m3/hm2; overflowing amount was 1 026.00 m3/hm2. In addition, water consumption totaled 8 884.50 m3/hm2 during rice production; water use was 0.99 kg/m3 and use efficiency of irrigated water was 1.40 kg/m3. [Conclusion] Water supply and consumption should be further organized to save water and fight against drought in hilly areas in Sichuan Province.[目的]研究稻田供水与耗水情况对水稻节水抗旱作用。[方法]该研究利用控制性田间试验,研究了四川丘陵地区水稻田间水分供需平衡关系。[结果]丘陵地区降水3611.10m3/hm2,灌溉用水6299.25m3/hm2;水稻腾发6424.95m3/hm2,深层渗漏2459.55m3/hm2,漫田溢出1026.00m3/hm2。水稻生产全程耗水8884.50m3/hm2,其中水分利用效率为0.99kg/m3,灌溉水利用效率为1.40kg/m3。[结论]在四川丘陵地区,应进一步协调稻田供水与耗水,从而实现抗旱节水有待进一步研究。
