Reference crop evapotranspiration (ET0) and new wetness index were both calculated and analyzed according to Penman-Monteith scheme recommended by FAO with routine meteorological data from 616 weather stations in China from 1975 to 2004. In terms of grades of wetness index from Chinese Climate Classification Criterion, China is classified into severe arid, arid, semi-arid, semi-humid and humid zones, respectively, which are compared with the demarcations from rainfall-based indices in order to reveal the similarity and difference in association with the two schemes under current global climate warming. Besides, the spatio-temporal analysis of climate wetness over the country in the past thirty years was performed.

依据中国616个地面气象台站1975年至2004年的日气象资料，利用联合国粮农组织推荐的参考蒸散计算方法，计算参考作物蒸散（ET0）和湿润指数，按照中国气候区划中的干湿指标把中国分为极干旱、干旱、半干旱、半湿润和湿润气候区，并与传统的降水量干湿指标进行对比，揭示在全球气候变化下两种干湿指标的异同，最后对中国近30 a干湿状况进行时空分析。
