【摘要】 运用数理统计方法,对广西澄碧河水库上游流域气候变化特征进行分析,结果表明:水库降水量的变化以减少为主,春季、秋季和主汛期降水量的减幅均较大;平均气温均呈显著增高趋势,其中冬季增幅最大;蒸散量的变化均呈减少趋势。并探讨了气候变化对澄碧河水库上游流域的影响,总体来看,弊大于利;提出了水库应对气候变化的若干措施和建议。更多还原

【Abstract】 Using mathematical statistic method,the climatic characteristics of Chengbihe Reservoir upper basin were analyzed.The results show that the precipitation of reservoir is mainly reducing trend especially in spring,autumn and the main flood season.The mean temperature shows an significant increasing trend especially in winter To the contrary,the evapotranspiration shows a decreasing trend.Then the climatic impacts on the reservoir upper basin was also dicussed.更多还原
