| 摘 要： | 根据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; 分析入库径流量变化趋势，并在对陆浑地区降水、气温、蒸发特征分析的基础上，讨论降水、气温、蒸发与径流的关系问题，以及影响陆浑水库来水的主要因素。结果表明：降水是影响陆浑水库入库水量的主要因素，气温对其影响没有降水显著；入库径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。 |
| 关 键 词： | 小流域；径流量；降水；气温；陆浑水库 |

| Abstract： | This paper adopts Mann-Kendall trend analysis method, Spearman rank related test and slide t detected method to apply significance test to the inflow runoff of two reservoirs basing on the actually measured monthly average runoff, the air temperature, and precipitation data; analyzes the inflow runoff variation trend; and discusses the relationship of the precipitation, air temperature, evaporation and the runoff, and the main factors influencing the Luhun reservoir inflow runoff basing on analysis of the precipitation, air temperature and evaporation characteristics of Luhun area. The results show that: precipitation is a main factor affecting the Luhun reservoir inflow runoff, which is more significant than air temperature; the inflow runoff has the same change trend with that of the precipitation, and the opposite one to that the air temperature, namely, the inflow runoff increases with the precipitation increase and decreases with the air temperature increase. |
| Key words： | the little basin; runoff; precipitation; air temperature; Luhun reservoir |
