Increased water-dependent development and utilization have led to significant environmental and hydrological degradation of the Tarim River in western China and its dependent ecosystems. Between the 1950s and 1970s, 350 km of the lower reaches were drained and between 1960 and 1980 the water-table fell from between -2 and -3 m to between -8 and -10 m. Subsequently, riparian ecosystems were seriously degraded. In 2000, the Chinese government launched a program to restore the lower reaches of the river. Four environmental flows of 1034 x 10(6) m(3) were released from 2000 to 2002. This paper interprets and discusses the ecological significance of changes following the releases and identifies the relationship between water-table dynamics and vegetation responses. Short-term objectives for river restoration are proposed with possible monitoring parameters suggested.
对水的依赖不断增加的开发和利用，已导致中国西部塔里木河及其相关生态系统出现严重的环境和水文退化。在20世纪50年代至70年代期间，下游350公里的河道干涸，1960年至1980年间，地下水位从-2至-3米降至-8至-10米。随后，河岸生态系统严重退化。2000年，中国政府启动了一项恢复塔里木河下游的计划。在2000年至2002年期间，排放了4次环境流量，每次流量为1034×10⁶立方米。本文解读并讨论了放水后变化的生态意义，并确定了地下水位动态与植被响应之间的关系。文中还提出了河流恢复的短期目标，并给出了可能的监测参数。
