| 摘 要： | 利用西峰农业气象试验站１９８９－１９９０和１９９０－１９９１年度旱作麦田土壤水分观测资料，采用零通量面法计算农田蒸散。结果表明，在旱农地区存在稳定少变的零通量面位置；农田蒸散随时间的变化一般多呈双峰型，但其谷值均在８月８日。

| Abstract: | Using Observational data of soil moisture of dry wheat field in Xifeng agromete-orological station in 1989-1990 and 1990-1991,by means of the method of Zero flux sur-face that calculates farmland evapotranspiration. The resuLts show that positions of Zero fluxsurface tended to stabilize. Farmland evapotranspiration often appears by bimodal distribu-tion. But its valley value appears on August eighth. |
