摘要
微气象学方法测定草地植被蒸散量具有方便简单,精度高的优点。还可用于预测预报,因此具有广泛的应用前景。本文主要介绍了目前国外广泛采用且精度较高的3种微气象学方法,即能量平衡法、彭曼法和蒙蒂斯—彭曼法,特别是各法中参数的确定方法。以期使该法能在我国草地生态系统的研究中得到应用和发展。
The micrometerological methods of measuring the evapotrans—pirations o grassland vegetations are easy to handle in field and have advantages in accuracy, reliability, and also can be used for forecastingthe evapotranspirations of vegetations based on climate information, so the methods will be widely used. Three micrometerological methods——energe balance method, Penman method. Monteith——Penman method that are now widely used in abroad and have great advantages in accuracy. especially the methods of establishing the parameters in the formulas of the three methods are outlined to make the methods be applied and developed in the studies of the grassland ecosystems of our country.
