黄旗海位于乌兰察布盟察右前旗境内,最大水面积曾达20万亩左右,盛产驰名全国的官村鲫鱼,最高年产量曾达1,200余吨。近年来,水位下降,水面积缩小,水质变坏,致使几种养殖鱼类于1970年开始逐步死亡,一年比一年严重,终于全部绝迹。据调查分析,此海水与鱼体的放射性都在正常范围内,鱼体的糜烂处也无致病,造成死亡的重要原因是水的化学性质的变化。从1964年到1973年 pH 值移向较高的碱性而
Huangqihai is located in the territory of Wulanchabu alliance right before the flag, the largest area of about 200,000 acres of water, rich in well-known national village carp, the highest annual output has reached 1,200 tons. In recent years, the water level has dropped, the water area has been reduced, and the water quality has deteriorated. As a result, several farmed fish began to gradually die in 1970, becoming grave each year and finally extinct. According to the survey and analysis, the radioactive seawater and fish are in the normal range, no erosion of the fish disease, the main cause of death is the change of the chemical properties of water. From 1964 to 1973 the pH shifted towards higher alkalinity
