摘　　要：为了提高农田水分管理降低渍害对农作物的影响,开发了基于田间积水及作物根区水分信息监测的农田渍害智能化预警系统.该系统由水分信息传感器、数据采集及无线传输模块、数据处理模块、农田渍害预测以及灾情结果发布模块6部分组成,可实现农田积水及土壤水分状况的连续监测,并通过无线传输系统将农田实时水分信息传输至数据处理终端,根据该系统预测部分的决策支持系统对农田渍害进行评估和预测.在田间试验的基础上,确定了该系统预测模块数学模型中的相关参数,提出了适用于农田渍害评估和预报方法.实地应用结果表明,实时监测结果及预警精度均能达到农田水分管理的需求,而且该系统监测部分小巧轻便,预警终端部分界面友好,操作简单,实用价值较高.对提高当地排涝管理水平、减小农田渍害对农业生产的影响具有显著效果.In order to improve the water management in the farmland and reduce the influence of waterlogging damage on crops,the intelligent warning system for farmland waterlogging was designed based on the real time monitoring of water information in crop root areas.The system is composed of 6 parts： water information sensor,data acquisition and wireless transmission module,data processing module,farmland damage prediction and disaster release module,which can continuously monitor farmland water accumulation and soil moisture status,and transfer the data through the wireless transmission system,then evaluate and forecast the waterlogging.Based on the field experiments,the parameters in the mathematical model are determined,and a method for evaluating and predicting farmland waterlogging damage is proposed.The results of application indicate that the real time monitoringresults and warning accuracy can meet the demand of farmland water management,moreover the monitoring module of this system is small and portable,and the software module has friendly interfaces and simple operations.Applicating this system has the striking effect on improving the drainage management level and reducing the damage of farmland waterlogging.
