摘要
根据云南省33个气象站点近60年的气象及近10年农业种植结构等资料,计算了参考作物需水量,分析了云南省参考作物需水量区域分布特征,利用曼-肯德尔(Mann-Kendall)趋势检验法检验,揭示了云南省气候变化及参考作物需水量变化趋势,研究了云南省农业种植结构、节水灌溉面积和农业用水特征。
60 years’meteorological data of 33 weather stations and 10 years’agricultural planting data in Yunnan province were collected to calculate reference crop evapotranspiration(ETo),and explore the regional distribution characteristic of ETo.The changing trends of ETo were analyzed using Mann-Kendall method.We also investigated the characteristic of agricultural planting structure,water-saving irrigation area and agricultural water consumption.
