金藻及黄藻类在煤矿塌陷区水域难生长的原因探讨

利用对比分析的方法,在同一城市选择煤矿塌陷湖和不受煤矿开采影响的湖泊两种水域,通过一年四季的取样、监测,研究金藻及黄藻类生长的环境条件,找出了煤矿塌陷湖水中金藻及黄藻类难生长的原因是:排入塌陷湖中的矿井水透明度低、矿化度高、亚铁和硫化物含量较高,以及生活污水有机质、氨氮等含量高所导致。从而为煤矿塌陷区生态环境的生物学评价提供了参考。 

Discussion on the reasons for Chrysophyta and Xanthophyta seldom growing in the water of mining subsidence area

The authors choose two types of waters of which one is mining subsidence lake and another is a general lake which are not affected by mining,to study the environment conditions of Chrysophyta and Xanthophyta growing with comparative analysis method.The reasons for Chrysophyta and Xanthophyta seldom growing in the water of mining subsidence area are low transparence and high degree of mineralization,and much more content of Fe2 and sulphide in the mine drainage,much more content of organic and ammonia-nitrogen in the domestic sewage drained to mining subsidence area by monitoring during the four seasons of a year.The study achievements have provided a reference for us using biological method to appraise the ecological condition of mining subsidence area.
