摘　　要：针对内蒙古东乌珠穆沁旗造纸废水污染致使草地植被严重退化问题,于2011年采用样线-样方调查方法对该造纸厂废水迹地草地植被进行了调查,以了解废水污染对草地植被的影响程度及危害的持续性。结果表明:废水迹地植物数量少,仅有33种,多样性低;迹地中心群落高度(15.01cm)和盖度(14.31%)小。距离废水迹地中心越近,一年生植物越多,多年生植物越少。迹地中心主要为碱蓬(Suaeda glauca)-白刺(Nitraria tangutorum)-群落,重要值高(58.87),并存在成片裸地。废水迹地草地植被仍处于严重退化状态,远未有效恢复。In order to understand the sustainability of the influence and harm, plant community was investi- gated in 2011 using the method of line transect -sample plots for the grassland damaged seriously by the waste water of paper mill in East Ujimqin Banner. Results showed that the plant community had a few species （33 spp. ）, less diversity, lower community height （15.01 cm） and sparser coverage （14.31~）. There were more annual and fewer perennial plant species survival in the center of tested grassland. In the center area, Suaeda glauca -Nitraria tangutorum was a dominant community and community mean impor- tant value was 58.87. There were also large patches of bare ground. The vegetation was still in a severely degenerate state and not yet recovered effectively.
