| 摘 要： | 根据塔里木河下游不同断面、离河岸不同距离胡杨的现地调查数据，得出随着离河岸距离增加胡杨林密度降低、株间距加大的规律。以推断塔河下游断流30年问，地下水对胡杨的支撑极限和胡杨对干旱的耐受极限，为塔河下游生态治理以及应急输水方案的调整提供依据。

| Abstract: | Based on investigation in lower reaches of Tarim River the author found some rules as the follows: The population density of Populus Euphratica and the plant distance increase with the distance to the Tarim River increasing. The conclusion could provide evidence for ecology management and emergency output water in the lower reaches of Tarim River through analyzing the maximal Populus Euphratica living scope that the underground water could support and the doughtiest level that the Populus Euphratica could survive. |
