云南省渔洞水库山区流域降雨径流过程模拟
Simulation of Rainfall Runoff Process in Mountainous Areas of Yudong Reservoir Yunnan Province
摘要
Abstract
Precise estimation on precipitation and evapotranspiration in mountain areas is essential for understanding rainfall-runoff processes and at the same time also a difficult problem in runoff simulation and prediction. This paper studied the influence of three potential evapotranspiration schemes and three precipitation correction schemes compared with the Yudong Reservoir mountainous areas in the basin of Yunnan Province. The results showed that the accuracy of the simulation was higher than that of the unadjusted ones by using different precipitation correction schemes and evaporation elevation correction schemes separately, besides, the combination of any precipitation correction schemes and the evaporation elevation correction schemes could achieve better runoff simulation results;it demonstrated that the P-M and Allen schemes had some adaptability to the mountainous watersheds, however, the P-M and Allen schemes simulation results were still lower than the 20 cm observation scheme which demonstrated the importance of observational evaporation data;the observed precipitation data were lower than the modified rainfall which indicated that the adoption of precipitation correction had a certain effect on the actual composition of each component in the runoff process.关键词
