天津水源严重不足迫在眉睫1980年华北地区大旱,海河上游没有来水,供天津城市用水的海河干流、独流减河、北大港水库、团泊洼水库及于桥水库等都没有蓄上水。1980年1至7月由密云水库供天津市水7.1亿立米。8月至1981年6月底,从密云水库供天津市的水量降到4.85亿立米,相当上年同期天津市实际用水14亿立米的三分之一。1981年人汛以来。华北地区持续干旱,到8月中旬海河流域各水系都没有产生洪水,上游各大水库均未蓄上水。气象部门分析,海河流域当年汛期降雨“盛期”已过,大面积降暴雨已不可能。
Serious shortage of Tianjin water shortage imminent In 1980, the drought in North China, the upper reaches of the Haihe River without water for the city of Tianjin, the mainstream of the Haihe River, Autonomous River, the Beidagang Reservoir, Mission Park reservoir and the Yuqiao Reservoir, etc. are not stored in the water. From January to July 1980, Miyun Reservoir was used to supply 710 million cubic meters of water in Tianjin. From August to the end of June 1981, the amount of water supplied from Miyun Reservoir to Tianjin dropped to 485 million cubic meters, equivalent to one-third of the actual consumption of 1.4 billion cubic meters of water in Tianjin in the same period of last year. Since the flood in 1981. Drought continued in North China. By the middle of August, there was no flood in all river systems in the Haihe River Basin, and none of the major reservoirs in the upper reaches accumulated water. Meteorological department analysis, the Haihe River Basin rainfall in the flood season “peak” has passed, a large area downfall has been impossible.
