| 摘 要： | 趋于咸化是淡水湖泊退化的重要标志之一。自2003年以来,官厅水库库区矿化度明显增加,咸化趋势明显。通过对官厅水库水化学特征演化规律的研究,发现官厅水库水体由中等矿化度水逐步向较高矿化度水转变,由软水逐步演化到硬水,水化学类型从重碳酸盐类转变为氯化物类,分析水库上游来水、水库蓄水量等因素对水化学特征带来的影响,提出了保持水库水化学稳定的合理建议。

| Abstract: | Salinization is an important sign of degradation for freshwater lakes.The content of salinity has been increasing obviously and salinization is clear for the Guanting reservoir since 2003.This paper discusses the evolution of hydro-chemical characteristics and the result shows that the hydro-chemical characteristics of Guanting Reservoir has changed from moderate emineralization to higher emineralization,from soft water to hard water,and hydro-chemical types from HCO3-to Cl-.It is explored that the inflow to Guanting reservoir and storage capacity have an effect on hydro-chemical characteristics.Reasonable advice is suggested to keep hydro-chemical characteristics stable. |
