  ①问题出在30多年。塔里木河两岸人口激增,水的需求也跟着增加。扩大后的耕地要用水,开采矿藏需要水,水从哪里来?人们拼命向塔里木河要水。几十年间塔里木河流域修筑水库130多座,任意掘堤修引水口138处,建抽水泵站400多处,有的泵站一天就要抽水1万多立方米。     

  ②盲目增加耕地用水、盲目修建水库截水、盲目掘堤引水、盲目建泵站抽水,“四盲”像个巨大的吸水鬼,终于将塔里木河抽干了,使塔里木河的长度由60年代的1321公里急剧萎缩到现在的不足1000公里,320公里的河道干涸,以致沿岸5 万多亩耕地受到威胁。断了水的罗布泊成了一个死湖、干湖。罗布泊干涸后,周边生态环境马上发生变化,草本植物全部枯死,防沙卫士胡杨林成片死亡,沙漠以每年3 米至5 米的速度向湖中推进。罗布泊很快与广阔无垠的塔克拉玛干大沙漠浑然一体。

The twin towns of LAUFEN/OBERNDORF

Laufen owes its former economical and cultural significance to the river Salzach,which forms a peninsula with its sharp curves(弯) there.

Laufen’s economic boom began with the salt trade and the shipping on the river.The salt—mainly coming from Hallein and Bad Reichenhall—was loaded onto bigger ships downstream,which made Laufen one of the most important ports of shipment for salt in Salzburg and Bavaria.

The archbishop(大教主) of Salzburg had given special privileges to the people who were involved in the shipping of salt on the river Salzach.

The Napoleonic Wars brought occupation and serious disturbances.They brought the sudden end to the independent state of the Duke—Archbishop of Salzburg.The end of the 18th century brought a decrease in shipping because of the general economic situation.On the 1st May 1816 Salzburg definitively became a part of Austria (Munich agreement) that’s why the Salzach became the border between Bavaria and Austria.Laufen’s suburbs Oberndorf and Altach were divided up.The number of inhabitants fell from 1392 to 809.Even the re-unification of the two towns’shipsmen’s guilds(行会) and the reorganization of 1928 could not prevent the decline of shipping which finally came to an end in the late 19th century.
