利用平均温度法预报树木物候期是一种新的预报方法。此方法是通过绘制树木物候曲线和当地的热量资源网来进行的。用此种方法预报树木物候期精度高而使用方便。本文利用北京地区1951～1985年气象资料和树木物候资料以及1990年树木开花期资料进行树木始花期预报,得到比较满意的结果。
Prediction of tree phenophase using the average temperature method is a new prediction method. This method is done by plotting the tree phenology curve and local thermal resource network. In this way, the prediction of tree phenology with high precision and easy to use. In this paper, we use the meteorological data and tree phenological data from 1951 to 1985 in Beijing area and the flowering date of trees in 1990 to forecast the flowering period of trees, and get the satisfactory results.
