摘要
根据鲇鱼山水库和陆浑水库实测的月平均流量、气温、降水量资料,采用Mann-Kendall趋势分析法、Spearman秩次相关检验、滑动t检验法对两座水库的入库流量进行显著性检验;建立了有关径流—降水—气温的数学模型,并对其敏感性进行了分析。研究结果表明:陆浑水库和鲇鱼山水库的入库流量对降水变化的响应比对气温变化的响应更为显著。入库流量与降水变化趋势一致,与气温变化趋势相反,即随降雨量的增加而增加,随气温的升高而减少。
This study has adopted the nonparametric Mann-kendall test, Spearman correlation test and running t test to test inflow runoff significantly for the two reservoirs in terms of the data of Nianyush- an reservoir and Luhun reservoir on monthly mean runoff, temperature and precipitation. Build up runoff-precipitation-temperature model with sensitivity analysis. The results show that inflow runoff has made a greater response to precipitation than on temperature change between Nianyushan reservoir and Luhun reservoir. The inflow runoff keeps the same trend with precipitation but against with temperature, which means that the inflow runoff increases as the precipitation increases and decreases as the temperature decreases.
