摘要

[目的] 分析内蒙古乌梁素海水体透明度的时空变化及其影响因子，为乌梁素海的沉水植物恢复及湖泊管理治理提供理论依据和技术支撑。[方法] 根据2014年4月至2015年1月乌梁素海常规监测数据及试验数据，并采用Excel和SPSS软件进行分析，探讨乌梁素海水体透明度的影响因子。[结果] 2014年4月至2015年1月乌梁素海水体透明度范围为0.17～2.74 m，平均值为0.82 m，透明度分布的总体格局是：南部湖区>北部湖区。透明度的季节变化表现为全湖平均透明度春季（1.12 m） > 秋季（0.81 m） > 夏季（0.73 m） > 冬季（0.61 m）。[结论] 叶绿素a是影响水体透明度的最主要因子，随着叶绿素a浓度的增加，透明度呈下降的趋势。而悬浮物的浓度并不是影响水体透明度的主要因素，pH值对水体透明度的影响是间接的。

Abstract

[Objective] The objective of the study is to analyze the spatial-temporal changes of water transparency and related influencing factors in Wuliangsu Lake

Inner Mongolia and to provide theoretical basis and technical support for submerged plants recovery and lake management of Wuliangsu Lake.[Methods] According to the routine monitoring data and experimental data in Wuliangsu Lake from April 2014 to January 2015

this paper used Excel and SPSS to analyze the factors influencing water transparency of Wuliangsu Lake.[Results] During the April 2014 to January 2015

water transparency of Wuliangsu Lake ranged from 0.17 to 2.74 m with an average value of 0.82 m. The water transparency was higher in south area than in north area. The seasonal variation of the transparency was spring(1.12 m) > autumn(0.81 m) > summer(0.73 m) > winter(0.61 m).[Conclusion] Chlorophyll a is the most important factor affecting the spatial distribution of water transparency which decreases with its increases. The suspended solids is not the important factor on water transparency

pH value is an indirect factors influencing water transparency.
