中文摘要	2000年5月中旬至7月中旬向塔里木河下游断流河段应急输水，历时60天，输水2亿m~3。其后对进水河段分5个断面考察了沿岸植被的生长发育、恢复状况、草本植物地表生物量，根系的分布与数量、植被的分布特点、土壤状况及地下水分布等，通过比较分析，初步结论如下：1、断流河道应急输水对沿岸植被恢复作用显著，其中草本植物效果明显，灌木次之，乔木较差；2、非风积土壤效果更佳；3、应急输水加人工保护与更新则效果更好。
英文摘要	The water consumption for the agricultural production an the natural vegetation can not be ensured downstream from Daxihaizi Reservoir at the lower reaches of Tarim River owing to the reduction of the feeding water, and the accumulated time of stream cut-off here has bee as long as 10 ～ 20 years. Because of shortage of water, the desertification is sped up, wind erosion becomes violent, the ecological environment is degenerated, and the desert forests along the banks of Tarim River downstream from Daxihaizi Reservoir will disappear if the situation is not changed. Therefore, a stream water volume of 2.0 * 10~8 m~3 was fed to the stream cut-off river section at the lower reaches of Tarim River in an emergency during the period from mid-May to mid-July. Later 5 sections are investigated, which include the regenerating and stowing situation of the plants, biomass of the grasses, distribution and quantity of the roots, distribution characteristics of the natural vegetation, soil status, distribution of groundwater, etc., along the river banks. The results show that the effects of the emergency stream water feeding to the stream cut-off river section to the regeneration of the natural vegetation along the river banks are obvious, especially to the grasses, then to the shrubs and trees.
