新疆内陆干旱区河流日径流模拟比较分析

Comparitive Analysis of Simulated Daily Runoff for the Rivers of Inland Arid Area in Xinjiang

本文选用水箱模型、萨克拉门托模型和自适应修正预报模型,对新疆部分河流的日径流过程进行了模拟,并对其模型的适用条件和特点作了比较分析。根据新疆内陆干旱区河流的特点和产流特性,对融雪、蒸散发计算和模型结构作了改进。用改进后的模型,在乌鲁木齐河、头屯河、哈什河、布尔津河以及昆马力克河的日径流过程模拟中,取得了较满意的结果。

By using Tank model, Sacramento model and forecasting model of self-adapting amendment, the paper simulates daily runoff processes for some rivers in Xinjiang and compares suitable conditions and characteristics of these models. The calculation of snowmelt, evaporation and transpiration as well as model structure are improved according to the characteristics of the rivers and discharge properties in inland arid area of Xinjiang. The simulation results are rather satisfactory for Urumqi river, Toutun river, Hashi river, Buljing river and Kunmalik river in Xinjiang Region.
