Improved Water Ecology in Shandong

山东是人口大省、经济大省，也是一个水资源严重短缺的省份。全省多年平均降水量为679．5毫米，多年平均水资源总量仅有303亿立方米，人均334立方米，不到全国人均的1／6，仅为全球人均的1／25。 小清河变清了 2010年初，山东省省长姜大明在政府工作报告中提出以“恢复鱼类生长”作为当年省控59条重点污染河流治理目标。同年12月底，山东59条重污染河流化学需氧量和氨氮平均浓度分别为每升水23．7毫克和每升水1．4毫克，比上年同期分别下降40．4％和61．7％。按常见鱼类能够稳定生存的技术指标衡量，这59条重污染河流已经全部稳定恢复鱼类生长，标志着山东水生态环境得到根本改善。

In early 2010, in the government work report, Shandong Provincial Governor Jiang Daming put forward regarding ＂restoring the fish growth＂ asthe goal of reducing the pollution of 59 key rivers under provincial control. At the end of December of the same year, the chemical oxygen demand and ammonia average concentration of the 59 heavily polluted rivers hit 23.7 milligrams per liter of water and 1.4 milligrams per liter of water, a decrease of 40,4% and 61.7% respectively over the same period of the previous year. Evaluating by the indexes under which the common fish can survive, the 59 heavily polluted rivers had all restored the environment for the growth of fish, which symbolized that the water ecological environment of Shandong had been fundamentally improved,
