摘要
分析了莲花水库上游流域近40 a的气候变化,结果表明年降水量呈略增加趋势,年平均气温呈非常显著的变暖趋势,年潜在蒸散量呈略减少趋势。建库前后对比分析表明,建库后比建库前有显著差异的是年平均气温升高,年平均风速减小,相对湿度、日照时数减少。
To analyze the climate change of Lianhua Reservoir upstream valley nearly 40 years,the annual precipitation shows a slight rising trend,the average temperature of the whole year shows a remarkable warming trend,and the annual potential evaporation shows a slight decreasing trend.Comparison of the construction before and after,the significant difference is that the average temperature of the whole year is warming,and annual average wind speed,relative humidity,sunshine-hour is reducing.
