摘　　要：以中科院栾城农业生态试验站的田间灌溉试验为基础,以荷兰Wageningen农业大学等单位开发的土壤-水分-大气-作物系统模拟软件SWAP软件为工具,应用试验站的土壤、水分试验资料对模型的参数进行了率定和验证.在此基础上设计了该地区不同降水水平年、不同灌溉定额下的多种灌溉方案,并应用SWAP软件模拟了各种方案的农田水分平衡情况,提出了在当地平水年份下冬小麦灌水5次,夏玉米灌水1次的灌溉指导方案,其研究结果对该地区的农田水分利用具有一定的借鉴意义.Based on field experiments of the water irrigation which have been conducted in the Luancheng Agriculture Experimental Station of CAS,SWAP（Soil-Water-Atmosphere-Plant）model developed by Wageningen Agricultural College was used as an analysis tool. The parameters in the model were calibrated with the data of irrigation experiment. Some kinds of irrigation schedules in different flow years and certain irrigation quotas in this region were developed. The different irrigation quotas based on different irrigation schedules were simulated with SWAP model. The guidance irrigation schedule was put forward as 5 irrigation times in winter-wheat field and 1 irrigation time in the summer-maize field in median flow year. The optimal irrigation schedule would be useful for reference of water use of farmland in .this region.
