博斯腾湖矿化度影响因子的敏感度分析

Sensitivity analysis on influence factor of salinity in Bositeng Lake

水位,吞吐流,风场从不同机理不同程度影响着博斯腾湖的矿化度分布。本文在定性分析博斯腾湖矿化度分布的影响因子的基础上,建立水流-盐度数学模型,通过采用单因子影响的分析的方法,进行矿化度分布对各影响因子的敏感度分析。研究表明:风场对博湖矿化度分布的影响最为明显,水位和吞吐流对博湖矿化度分布的影响均不明显。该研究对博湖的水环境综合治理有一定的指导意义。

The water level,discharge and wind field affect the salinity distribution in Bositeng Lake from the different mechanisms and levels.Based on the qualitative analysis of the influence factor of salinity distribution in Bositeng Lake,the paper established water flow-salinity mathematical model,carried out the sensitivity analysis for each impact factor by using the single-factor method.The research indicated that the wind field has the most obvious influence on salinity distribution,but the influence of water level and the discharge on salinity distribution in Bositeng Lake is not obvious. This study have certain guiding sense to the water environment comprehensive improvement of Bositeng Lake.
