Abstract: In order to understand the sustainability of the influence and harm, plant community was investigated 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 important 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.

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(15.01 cm)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。
