摘要
采用1998年联合国粮农组织推荐的彭曼─蒙特斯公式计算了汉江流域参照作物腾发量,利用Mann─Kendall检验方法和空间插值方法,分析了1961─2000年汉江流域春、夏、秋、冬四季参照作物腾发量和小型蒸发皿蒸发量变化趋势的时空分布。分析结果有助于进一步研究气候变化对汉江流域水资源的影响。
The paper adopts the Penman-Montelth method which was redefined by the FAO in 1998 to calculate the reference evapotranspiration in Hanjiang River basin and the Mann-Kendall trend test and the spatial interpolation method to analyze the temporal and spatial trends of the reference evapotranspiration in the Hanjiang River basin in all the year during 1961-2000, The research results are helpful in further studying the impact of climate change to water resources in the Hanjiang River basin.
