莆仙平原作物生长季和夏旱期降水量数学模拟与应用

Mathematics imitation for precipitation in Putian xianyou Plain in the crop growth season and summer dry period, as well as its application

以莆田县气象站作为莆仙平原的代表站 ,利用谐波分析方法对该站 196 1- 1997年共 37a中历年作物生长季 (3- 11月 )和夏旱期 (7- 9月 )的降水量进行数学模拟 ,得到了该站这两段时间的模拟式 。

Harmonic analysis was used to carry out mathematics imitation for precipitation in Putian Xianyou Plain in the crop growth season (from March to November) and summer dry period (from July to September) during 1961-1997 (a total of 37 years), based on the data from Putian Meteorological Station, and the two mathematical models were obtained. Meanwhile, the change of precipitation in this region in the crop growth season and summer dry period was analysed and the measures to prevent from drought were suggested.
