摘要
以漳河水库灌区1966-2005年水稻产量和灌溉供水量实际数据为依据，对水稻产量变化和水资源利用效率进行了分析，对水稻产量和灌溉水分生产率增长的主要因素进行了探讨。在水稻种植面积和灌溉用水量减少较多的情况下，水稻单产量稳步增长，水稻总产量变化不大，灌溉水分生产率的大幅度提高，提升了灌区内水资源的承载能力。
The changes in the rice production and water resources utilization efficiency were analyzed according to the actual data of rice production and irrigation water volume in the ZhangheReservoir Irrigation District during 1966--2005. The principal influence factors for the increase of rice production and irrigation water productivity were discussed. Under the condition of decrease of rice-growing areas and irrigation water volumes, the total output of rice remained stable due to the steady growth of rice yield. Therefore, the irrigation water productivity was enhanced with large range and the carrying capacity of water resources in the irrigation district was also upgraded.
