博斯腾湖水体矿化度变化趋势及调控研究

Study on variety trend and control about mineralization degree of Bositeng Lake

博斯腾湖水体矿化度自从20世纪70年代以来基本在1 0g/L以上,80年代矿化度曾经高出1 8g/L,目前还维持在1 3g/L左右。以实测数据为基础,阐述博斯腾湖水体矿化度的变化趋势;并以建立的水量 水质 生态系统模型为基础,探讨博斯腾湖水体矿化度变化的影响因素,从本质上分析控制博斯腾湖水体矿化度变化的主要因子,改变了从表象上认识的缺陷,提出了水体矿化度调控的对策。

Nowadays, Bositeng Lake is the biggest inland fresh water lake in China. However, the mineralization degree of the lake had preponderated over 1.0?g/L since 1970's, 1.8?g/L in 1980's, and now about 1.3?g/L. Based on the observation data, the variable trend of mineralization degree of the lake is discussed in this paper. The main and key factors that influence the mineralization degree of the lake are analyzed and decided by the water quantity-quality-ecology system model. Finally, countermeasures about mineralization control are put foreword.
