摘　　要：江西为农业大省,农田灌溉用水占全省用水总量比重较大,科学合理地预测未来农田灌溉的需水量,对水资源合理开发利用与管理尤为重要。在分析江西省水资源状况及农田灌溉用水现状的基础上,通过对全省农田灌溉面积的发展预测及灌溉净定额的分析计算和灌溉水利用系数的合理确定,采用定额法分别对全省2020,2030年不同保证率情况下的农田灌溉需水量进行了预测研究。预测结果满足江西省农业规划的需求,为研究制定全省水资源开发利用方案,加强水资源管理提供了决策参考依据。Jiangxi Province is a main agriculture one in China and its agriculture irrigation water amount is a large portion in the water consumption of Jiangxi Province. The scientific and reasonable prediction of irrigation ,sater demand in the future is extremely important to reasonable development and management of water resources. On the basis of the analysis on water resources and irrigation water condition at present, by prediction of the field irrigation area development, the calculation of irrigation quota and the reasonable determination of utilization coefficients of irrigation, the field irrigation water demands in 2020, 2030 under different assurance rates are predicted using rating method. The prediction result meets the demand of agriculture development plan in Jiangxi Province and provides reference for the water resources development plan and water resources management of Jiangxi Province.
