摘要
利用气温、降水等常规气象资料 ,建立了以旬为时间单位的农田土壤水分动态估算模式。并通过对昌图、庄河及朝阳三地作物生长季农田土壤水分估算的实例分析 ,验证了该模型的准确性。该模型的建立对干旱发生的预测、预警和合理安排农事活动具有实际意义。
Using temperature and precipitation meteorology data, dynamic estimate model of farmland soil moisture of every ten days was built. By estimating farmland soil moisture of crop growth season in Changtu, Zhuanghe and Chaoyang, the model reliability was verified. This model had practice significance for forecasting drought event and rationally arranging farming activity.
