Temporal and spatial changes of agricultural water requirements in the Lancang River Basin


, : Temporal and spatial changes of agricultural water requirements in the Lancang River Basin. Journal of Geographical Sciences 22(3): 441-450

Based on the data of eight meteorological stations from the 195s to 27, current cropping patterns, field water moisture management, we use the Mann-Kendall and the Rescaled Range Analysis methods to research the changes of humidity and crop irrigation water requirements in the Lancang River Basin. The results show that the annual and dry season average temperatures significantly increased, and the dry season rainfall increased while wet season rainfall decreased. Evaportranspiration (ET) increased during both dry and wet seasons at all stations except Dali, Jianchuan and Gengma, and the aridity-humidity index decreased at most of the stations. The turning points of weather factors, ET, the aridity-humidity index, paddy irrigation requirements and total agricultural water requirements occurred from the 196s to the 199s. The spatial changing tendency of paddy irrigation quota increased with the increase of altitude and latitude, and the correlation coefficients are .513 and .61, respectively. The maximum value is observed in Weixi, while the minimum in Mengla.
