(一) 张家口地区的水库建设,自1956年开始,到1984年底共建成生效的有各类水库124座,总库容7.15亿米~3,加上其他水利设施,全区水浇地面积己发展到216.6万亩,粮食总产达10.48亿公斤,比建库前的50年代增多29％,农业总产值达8.53亿元,比50年代增加了4倍多。但是,由于大部分水库是在“大跃进”年代和“文革”期间兴建的,遗留问题很多;据不完全统计,全区先后兴建的192座中小型水库中,有各种安全问题的119座,占水库总数的62％,其中工程标准低、质量差、安全渡汛存在严重问题的危险水库63座;带病运行的水
(1) Reservoir construction in Zhangjiakou area Since 1956, by the end of 1984, a total of 124 reservoirs of various types have been put into effect, with a total storage capacity of 715 million m 3. Coupled with other water conservancy facilities, the irrigated area has been developed To 2,166,000 mu, total grain output reached 1,048 million kilograms, an increase of 29% over the pre-establishment 1950s. Total agricultural output reached 853 million yuan, an increase of more than four times that of the 1950s. However, since most of the reservoirs were built during the “Great Leap Forward” and during the “Cultural Revolution”, there are still many remaining problems. According to incomplete statistics, there are 119 safety and security problems in 192 small and medium-sized reservoirs built in succession , Accounting for 62% of the total number of reservoirs, including 63 dangerous reservoirs with low engineering standards, poor quality and serious flood-safety problems; ill-running water
