| 中文摘要: |
| 通过对甘肃河东地区当前作物旱情指标的分析,选取了依据农田水量平衡原理而建立的作物水分供需比作为作物旱情指标,利用田间试验资料,建立了旱作小麦农田干旱监测预警指标模型,并确定出小麦旱情分级标准。以此为基础,编制了甘肃河东旱作小麦农田干旱监测预警系统软件,简要介绍了该系统的结构、功能及操作环境,并对预测精度问题进行了说明。 |
| 英文摘要: |
| In accordance to the water supply-requirement ratio based on the principle of farmland water equilibrium, the index model of drought monitoring and prediction for spring wheat in dry farmland in east part of Gansu province was established using the field experimental data, and the grade criterion of crop drought was determined. Furthermore, the software of service system of drought monitoring and prediction for spring wheat in dry farmland has been compiled. Finally, the frame and function of the system was briefly introduced, and the prediction precision of the system was explained as well. |
